Anti-hepatitis B Virus Activity of 8-epi-Kingiside in Jasminum officinale var. grandiflorum

Objective To evaluate the effect of 8-epi-kingiside (8-Epik) derived from the buds of Jasminum officinale var. grandiflorum (JOG) on hepatitis B virus (HBV) replication in HepG2 2.2.15 cell line in vitro and duck hepatitis B virus (DHBV) replication in ducklings in vivo. Methods The concentration of extracellular hepatitis B e antigen and hepatitis B surface antigen (HBsAg) in cell culture medium was determined by ELISA, respectively. The anti-HBV effects of 8-Epik were also demonstrated in the model of DHBV. 8-Epik was ip given (20, 40, and 80 mg/kg, twice daily) to the DHBV-infected ducklings for 10 d. The isotonic saline liquid diet was ip given as negative control and Lamivudine (50 mg/kg, twice daily) was given as positive control. DHBV DNA was measured at days 0 (T0), 5 (T5), 10 (T10), and day 3 after cessation of treatment (P3) by dot blotting. Results 8-Epik effectively blocked HBsAg secretion in HepG2 2.2.15 cells in a dose-dependent manner [IC50 = (19.4 ± 1.04) μg/mL]. 8-Epik (40 or 80 mg/kg, ip, twice daily) also reduced viremia in DHBV-infected ducks. Conclusion Therefore, 8-Epik is warranted as a potential therapeutic agent for HBV infection.

Phytopharmacological Profile of Jasminum Grandiflorum Linn. (Oleaceae)

Plants are the real basis towards animal life and are also central to people’s livelihood. The contributions of the plants in performing varied religious celebrations and in other multiple beneficiaries like medicine, human happiness as well as in treating deadly diseases can never be neglected. In treating diseases, the plants and their constituents are better choice than any other synthetic chemical. The nature has been kind enough to provide the human beings with various types of medicinal plants and in the real sense these form the storehouse of curing almost all the ailments. Consequently, most of the drugs which are being used in preparing formulations have their origin and roots in the plants which form the chief natural source of medicines. Even in modern era, the plant-derived drugs are being extensively used, either in their original or semi-synthetic form. It is because their natural phytoconstituents are highly innocuous posing relatively fewer or no side effects. Based upon their observations, analysis and experience, our ancestors used many plants for medicinal purposes and thus their efforts need to be supported by scientific evidence. Jasminum grandiflorum Linn. is one of such important plants. It has been extensively used by the tribes all over India to treat different diseases which mainly include body pains, toothache, stomach ache, ulcers, and sexual impotency. Chemistry of the plant revealed the presence of mainly secoiridoids, terpenoids, flavonoids and tannins. Not much scientific support was given to the folklore claims for this plant but some of its traditional uses were investigated like spasmolytic, wound healing, antimicrobial, angiotensin converting enzyme inhibitor, antiulcer and antioxidant activities. This article is the review of research works done on the plant Jasminum grandiflorum Linn. to date. As a part of it the local names, morphology, traditional claims, chemistry and pharmacological activities have been discussed.
