Ethanolic extracts of 30 Thai medicinal plants, traditionally used as alternative treatments in diabetes, were evaluated for antioxidative activity. Five plants had strong antioxidant activity: Amla Phyllanthus emblica Linn., Terminalia chebula Retz., Morinda citrifolia Linn., Kaempferia parviflora Wall. and Houttuynia cordata Thunb., respectively. Amla had stronger antioxidative activity than the other plants. The investigation showed that total polyphenol and tannin content of Amla and the flavonoid content of Houttuynia cordata were the highest. The results imply that these plants are potential sources of natural antioxidants which have free radical scavenging activity and might be used for reducing oxidative stress in diabetes.
