Abstract:
Pyrrosia longifolia is an epiphytic plant belonging to the Polypodiaceae family. It
grows on large, old trees. Since this plant is commonly found. It is used as a
herbal medicine. However, the anti-diabetic activity of this plant has not been
thoroughly investigated. According to the results of an in vitro α-glucosidase
inhibitory assay antidiabetic test against the α-glucosidase enzyme, the crude
extract of n-hexane inhibits the enzyme by 7.5 percent, dicloromethane inhibits
the enzyme by 16.2 percent, ethyl acetate inhibits the enzyme by 6.8 percent and
water inhibits the enzyme by 20.4 percent. It was concluded that the extracts of nhexane,
dichloromethane, ethyl acetate and water did not have good inhibitory
activity against the α-glucosidase enzyme.
