Comparison of biological activities of extracts from different parts of seabuckthorn (Hippophae rhamnoides L.)

초록

Biological activities of different parts (stems, leaves, roots, fruits) and solvents (water, ethanol) of seabuckthorn (Hippophae rhamnoides L.) grown in Korea were tested as follows. In the experiment of inhibiting α- glucosidase activity, ethanol extract of Hippophae rhamnoides L. stem showed the highest inhibitory activity by 93% and the next highest was the ethanol extract of its leaf by 88.7%. In the case of these two extracts, the effect of inhibiting α-glucosidase activity was extraordinarily great when comparing with control group, acarbose. In the experiment of inhibiting α-amylase activity, water extract of leaf showed the highest result by 54.7%, among all extracts. Regarding anticancer effect for HT-29 cell and DU-145 cell, water extract of root showed 47.1% and 32.3% activities, respectively. The experiment on antibacterial activity showed that the ethanol extract from the leaf inhibitory activity of Clostridium butyricum, Proteus mirabilis, and Shigella flexneri which are the several food borne pathogenic strains. In future research, materials for biological activity appear isolated and purified and research should continue.
