The inhibition activity on tyrosinase, xanthine oxidase, and lipase of parts grown in Vietnam.

Colla plant belongs to the family, which is well-known for its nutritional and pharmacological properties. This study aimed to evaluate the anti-xanthine oxidase, anti-lipase, and anti-tyrosinase activities of samples of corm, pseudostem, inflorescence, fruit, peel, and seed of . The results show that seed performed the highest capacity in the inhibition of three investigated enzymes, with IC values of 290.25 μg/mL (anti-tyrosinase), 141.51 μg/mL (anti-xanthine oxidase), and 25.66 μg/mL (anti-lipase). In addition, while fruit showed better performance in anti-lipase inhibition (IC: 32.72 μg/mL), corm pointed out higher capability on anti-xanthine oxidase (IC: 160.67 μg/mL) and anti-tyrosinase (IC: 334.43 μg/mL). The data show the high potential of the application of parts in medical aesthetics, dietary supplements, or medicine. This is the first report to systematically present the biological activities of all parts of grown in Vietnam.
