  Dried stems and leaves of Yha-nang dang (Bauhinia strychnifolia Craib.) have long been used in Thailand to make tea for promoting health and for detoxification of the body. The objectives of this study were to investigate antioxidant activities of B. strychnifolia dried stem and leaf extracts obtained by different extraction methods. The antioxidant power of B. strychnifolia extracts and water extracts of green tea leaves (Camellia sinensis) were evaluated using four different methods: DPPH radical scavenging assay, Ferric reducing antioxidant power (FRAP) assay, and Superoxide radical scavenging by NBT dye reduction assay, and measurement of total phenolic contents by the Folin-Ciocalteu colorimetric method. The 95% ethanolic extract of B. strychnifolia stems exhibited the strongest DPPH radical scavenging activity, with an EC50 value of 4.2 μg/ml. This was in agreement with resul.. View More»
