Study Findings
• Anti-Viral / Biflavonoids: Previous studies have yielded chromone glycosides (uncinoside A and B) which has shown good anti-tumor and anti-viral activity. This study isolated a new biflavonoids with five known compounds and one known phenolic acid. Preliminary study found the ethyl acetate extract exhibited good anti-HSV1 and Anti-COX B3 virus activity.
• Bioflavonoids / Anti-Anoxic: Study of ethanolic extract of S uncinata isolated four new and three known bioflavonoids. Compounds 4 and 5 showed potent anti-anoxic effect in the anoxic PC12 cell assay.
• Benzoic Acid Flavonoid: Study yielded a new flavonoid from the ethanol extract of S uncinata – 6-(5-carboxyl-2-methoxyphenyl)-apigenin, a first of a flavanoid with a benzoic substituent at C-6.
