1、蜂胶的来源及性状
蜂胶Propolls是由工蜂采集树木(主要是杨树、桉树、桦树和柳树等)以及某些草本植物枝芽或破皮分泌出的一种固体粘液,与其本身上颚腺分泌物、蜂蜡和少量花粉加工混合而成的一种物质。通常涂在蜂巢的周围和巢壁等地方,是蜜蜂本能地为了祛除病菌和虫害,保护群居生活生息繁衍的一种天然物质。 相似文献

Propolis, a resinous substance, is collected from plants and processed by honeybees to seal holes and cracks in beehives, protecting them from microbial infection. Based on the plant source and geographical location, propolis is categorized into seven groups. Of these, Pacific propolis, found in the Pacific islands, originates from Macaranga spp. and is, therefore, known as Macaranga‐type Pacific propolis. Okinawa propolis and Taiwanese propolis, which are both Macaranga‐type propolis, are rich in prenylated flavonoids from the same botanical source, Macaranga tanarius, and are used locally as traditional remedies. They are reported to have a wide range of pharmacological benefits, including antioxidant, anti‐inflammation, antimicrobial, anticancer, antidiabetic, anti‐Alzheimer's, anti‐melanogenic, and longevity‐extending effects. However, not much is known about their mode of action, and recently, the extract of Okinawa propolis and its major prenylated flavonoids were found to selectively inhibit the oncogenic kinase, p21‐activated kinase 1 (PAK1). PAK1 enables cross‐talking among several signaling pathways, causing many diseases/disorders. The existing results reviewed here support the use of Macaranga‐type Pacific propolis for the effective development of safe herbal drugs and functional foods. Furthermore, its mode of action by modulating PAK1 can be explored, and the geographical and seasonal effects on its chemistry and biology, and its pharmacokinetics and toxicology should be studied as well. 相似文献

Propolis has been used as a medicinal agent to treat infections and promote wound healing for centuries. The aim of the present study was to test the antimicrobial, antioxidant, and cytotoxic activities of a new type of Brazilian propolis, popularly called red propolis, as well as to analyze its chemical composition. The antimicrobial activity against Staphylococcus aureus ATCC 25923 and Staphylococcus mutans UA159 was evaluated and the chloroform fraction (Chlo-fr) was the most active with lower MIC ranging from 25 to 50 μg/ml. The hexane fraction (H-fr), having the highest concentration of total flavonoids, showed the best sequestrating activity for the free radical DPPH. The ethanolic extract of propolis (EEP) showed cytotoxic activity for the HeLa tumor cells with an IC50 of 7.45 μg/ml. When the EEP was analyzed by GC–MS, seven new compounds were found, among which four were isoflavones. Our results showed that the red propolis has biologically active compounds that had never been reported in other types of Brazilian propolis. 相似文献
