South African Salvia species: a review of biological activities and phytochemistry

The genus Salvia (sage) belongs to the Lamiaceae and encompasses 900 species worldwide of which ca. 26 indigenous species are found in southern Africa. Salvia is the largest genus in this family and constitutes almost one quarter of the Lamiaceae. In South Africa, the majority of Salvia species are distributed predominantly in the Cape region. Salvia species are used in many parts of the world to treat various conditions. Many sages, if not all, form an integral part of traditional healing in South Africa particularly in regions where they occur in abundance. Several species are used to treat microbial infections, cancer, malaria, inflammation, loss of memory and to disinfect homes after sickness. Despite the extensive traditional use and the general interest in phytoconstituents of Salvia it remains ironic that research on the South African counterparts has until recently been neglected. The review aims to collate recent research results on the phytochemistry and pharmacological properties of indigenous species. Bio-active compounds with antiplasmodial and antibacterial activities have been isolated and structurally elucidated from Salvia chamelaegnea, Salvia radula and Salvia verbenaca. The essential oil composition of Salvia showed the dominance of monoterpene hydrocarbons, oxygen-containing monoterpenes and oxygen- containing sesquiterpenes. Salvia runcinata is identified as an alternative source of natural alpha-bisabolol. Many pharmacological activities are summarised (anti-oxidant, antimicrobial, antiplasmodial, analgesic, antipyretic, anticancer, anti-inflammatory and antinociceptive) as a first attempt to provide scientific support for past and present local traditional uses.     

Senecio scandens Buch.-Ham.: A review on its ethnopharmacology,phytochemistry, pharmacology,and toxicity

Ethnopharmacological relevance

The aerial parts of Senecio scandens Buch.-Ham. (family Asteraceae) have a long history in traditional Chinese medicine as a treatment for various ailments, such as bacterial diarrhea, enteritis, conjunctivitis, and respiratory tract infections.

Materials and methods

A bibliographic investigation of Senecio scandens was accomplished by analyzing secondary sources, including the Chinese Medicinal plantal Classics, the Internet (Google Scholar and Baidu Scholar), and scientific databases accepted worldwide (Pubmed, Scopus, Web of Science, SciFinder, and CNKI). These sources were scrutinized for available information about the uses of Senecio scandens in traditional Chinese medicine, phytochemistry, pharmacology, and toxicology.

Results

Senecio scandens is a medicinal plant with a climbing woody stem. Phytochemical studies have shown the presence of numerous valuable compounds, such as flavonoids, alkaloids, phenolic acids, terpenes, volatile oils, carotenoids, and trace elements. Among them, PAs are the characteristic constituents, adonifoline is one of the index ingredients of Senecio scandens. Studies in modern pharmacology have demonstrated that extracts and compounds isolated from Senecio scandens show a wide spectrum of pharmacological activities, including anti-inflammatory, antimicrobial, anti-leptospirosis, hepatoprotective, anti-infusorial, antioxidant, antiviral, antitumoral, analgesic, mutagenic, and toxicological activities.

Conclusions

Phytochemical and pharmacological studies have demonstrated that the extracts of the plant possess various pharmacological activities that can be attributed to the presence of various flavonoids, phenolic acids, and alkaloids. Newer technologies for qualitative and quantitative methods of PAs need to be developed to obtain better accuracy and sensitivity. Due to the toxicity of PAs present in this medicinal plant, the regulations on PAs of Senecio scandens were varied among different countries and regions. In China, the PAs toxicity of Senecio scandens ranking criteria is not well defined in the Chinese Pharmacopoeia 2010, and there is no strict uniform requirement on the PAs in western countries. We propose that the use of Senecio scandens should be reevaluated based on a set of criteria, which includes risk–benefit analysis and severity of the toxic effects, clinical and preclinical data to ensure safe use while continuing to satisfy the need for access to the medicinal plant.

Devil's Claw-a review of the ethnobotany, phytochemistry and biological activity of Harpagophytum procumbens

Ethnopharmacological relevance

Harpagophytum procumbens subps. procumbens (Burch.) DC. ex Meisn. (Pedaliaceae) is an important traditional medicine growing in the Kalahari region of southern Africa where it is consumed as a general health tonic and for treating diverse ailments including arthritis, pain, fever, ulcers and boils.

Aim of the review

To provide a comprehensive overview of the ethnobotany, phytochemistry and biological activity of H. procumbens and possibly make recommendations for further research.

Materials and methods

Peer-reviewed articles on H. procumbens were acquired on Scopus, ScienceDirect and SciFinder, there was no specific timeline set for the search. A focus group discussion was held with different communities in Botswana to further understand ethnobotanical uses of the plant.

Results

Harpogophytum procumbens is used for a wide variety of health conditions in the form of infusions, decoctions, tinctures, powders and extracts. In addition to the common local use for arthritis and pain, other ethnomedicinal uses include dyspepsia, fever, blood diseases, urinary tract infections, postpartum pain, sprains, sores, ulcers and boils. Scientific studies revealed that H. procumbens exhibits analgesic, anti-oxidant, anti-diabetic, anti-epileptic, antimicrobial and antimalarial activities amongst others. Iridoid glycosides and phenylpropanoid glycosides have been the focus of phytochemical investigations as the biological activity has been ascribed to the iridoid glycosides (such as harpagoside and harpagide), which are common in nature and are known to possess anti-inflammatory activity. In addition, it has been shown that the hydrolysed products of harpagoside and harpagide have more pronounced anti-inflammatory activity when compared to the unhydrolysed compounds. Harpagophytum zeyheri is a close taxonomic ally of H. procumbens but H. procumbens is the favoured species of commerce, and contains higher levels of the pharmacologically active constituents. The two are used interchangeably and H. procumbens raw material is often intentionally adulterated with H. zeyheri and this may impact on the efficacy of inadequately controlled health products. The main exporter of this highly commercialised plant is Namibia. In 2009 alone, Harpagophytum exports were worth approximately €1.06 million. The high demand for health products based on this plant has led to over-harvesting, raising concerns about sustainability. Although only the secondary tubers are utilised commercially, the whole plant is often destroyed during harvesting.

Conclusions

Harpagophytum procumbens is used to treat a wide range of ailments. Some of the ethnobotanical claims have been confirmed through in vitro studies, however, when the constituents deemed to be the biologically active compounds were isolated the efficacy was lower than that of the whole extract. This necessitates the use of a different approach where all the metabolites are considered using a robust method such as spectroscopy; the phytochemical data can then be superimposed on the biological activity. Furthermore, there is a need to develop rapid and efficient quality control methods for both raw materials and products because the orthodox methods in current use are time-consuming and labour intensive.

Ethnopharmacological relevance

Safed musli (Chlorophytum borivilianum) is an eminent medicinal plant of India and considered as a ‘white gold’ or ‘divya aushad’ in Indian systems of medicine. In Ayurveda, Chlorophytum borivilianum belongs to the group of “Vajikaran Rasayana” corroborated to its rejuvenating, aphrodisiac, natural sex tonic properties and effective in alleviating sexual disorders. It is largely used as ethnic medicine by local healers of indigenous communities of India.

Materials and methods

A thorough bibliographic investigation was carried out by analyzing worldwide accepted scientific data base (Pub Med, SciFinder, Scopus and Web of Science), thesis, recognized books, non impact and non indexed journals.

Results

Traditionally, Chlorophytum borivilianum is well known for treating male impotency in India. The multi therapeutic and nutritional importance of Chlorophytum borivilianum is attributed to the rich source of phytochemicals particularly saponins. Recently, Chlorophytum borivilianum has gained a well established domestic (Indian) and international market for being the herbal alternative of “Viagra” without any side effects. Under the trade name ‘Nai Chetna’, the state government of Gujarat, India, has launched a novel potency drug from Chlorophytum borivilianum. Modern pharmacological studies of Chlorophytum borivilianum have demonstrated a wide range of pharmacological activities, most importantly aphrodisiac, immunomodulatory and anticancer activities.

Conclusion

The increased commercial exploitation of Chlorophytum borivilianum and low productivity of this endangered plant has raised the concern over its conservation. It has been envisaged that efforts should be made to standardize, encourage and popularize the cultivation of Chlorophytum borivilianum as a commercial crop. The analysis of previous pharmacological investigations suggested lack of substantial scientific evidences in various studies and do not stand the test of critical assessment. Due to high economic value, Chlorophytum borivilianum has also encountered a problem of adulteration with closely resembling medicinally inferior species. The studies available on toxicity, safety and quality of Chlorophytum borivilianum are inadequate for providing information on commercial utilization. Thus, the present review summarizes comprehensive information on Chlorophytum borivilianum and possible scope for future research to fill the existing lacunae on its different aspects of the study.

Aim of the review

To comprehend the fragmented information available on the botany, traditional uses, phytochemistry, pharmacology and toxicology of F. religiosa to explore its therapeutic potential and future research opportunities.

Materials and methods

All the available information on F. religiosa was collected via electronic search (using Pubmed, SciFinder, Scirus, Google Scholar, Agricola and Web of Science) and a library search.

Results

Ethnomedical uses of F. religiosa are recorded throughout South Asia, where it has been used for about 50 types of disorders. Phytochemical research had led to the isolation of phytosterols, amino acids, furanocoumarins, phenolic components, hydrocarbons, aliphatic alcohols, volatile components and few other classes of secondary metabolites from F. religiosa. Fresh plant materials, crude extracts and isolated components of F. religiosa showed a wide spectrum of in vitro and in vivo pharmacological activities like, antidiabetic, cognitive enhancer, wound healing, anticonvulsant, anti-inflammatory, analgesic, antimicrobial, antiviral, hypolipidemic, antioxidant, immunomodulatory, antiasthmatic, parasympathetic modulatory, esterogenic, antitumor, antiulcer, antianxiety, antihelmintic, endotheilin receptor antagonistic, apoptosis inducer and hypotensive.

Conclusions

F. religiosa emerged as a good source of traditional medicine for the treatment of asthma, diabetes, diarrhea, epilepsy, gastric problems, inflammatory disorders, infectious disorders and sexual disorders. Although many of the experimental studies validated its traditional medicinal uses, but employed uncharacterized crude extracts. Thus, it is difficult to reproduce the results and pinpoint the bioactive metabolite. Hence, there is a need of phytochemical standardization and bioactivity-guided identification of bioactive metabolites. The results of few pharmacological studies and bioactive metabolites already reported in F. religiosa warrant detailed investigation for its potential against cancer, cardiovascular disorders, neuroinflammatory disorders, neuropsychiatric disorders, oxidative stress related disorders and parasitic infections. The outcome of these studies will further expand the existing therapeutic potential of F. religiosa and provide a convincing support to its future clinical use in modern medicine.

The genus Broussonetia: a review of its phytochemistry and pharmacology

Plants belonging to the genus Broussonetia (Moraceae), which grow naturally in Asian and Pacific countries, have long been used in traditional Chinese medicine to treat various conditions, particularly tinea, dysentery, hernia and oedema. Various parts of plants of this genus such as the fruits, bark, leaves, flowers and roots are used medicinally. According to Flora of China, the inner bark fibre is used in making paper, and the wood is used for furniture. Several active compounds including coumarins, polyphenols, alkaloids, flavonoids, glycosides, lignans and diterpenes have been isolated from the plants of this genus in the past few years, and some members of these constituents have been demonstrated to exert antioxidant, antiinflammatory, antiplatelet, antityrosinase, antimicrobial and antinociceptive effects. Antidiabetic and antitumoural properties seem possible, but need further support. Due to the lack of clinical trials, there are few published reports on target-organ toxicity or side effects. Currently, some East Asian nations such as China, South Korea and Japan have shown increased interest in these plants. This article reviews the phytochemical and potential beneficial therapeutic effects of plants of this genus reported since 2000.
