Abstract

Two new flavones neocafhispidulin (1) and 6″-O-acetyl homoplantaginin (2), together with 10 known flavones and 1 polyphenol were isolated from the whole plants of Salvia plebeia. R. Br. Compounds 3 and 4 were reported from this plant for the first time. Their structures were determined by spectral analyses. Compounds 1-13 were evaluated for their anti-tyrosinase and anti-inflammatory activities. The results showed that compounds 1, 5, 8, 10 and 11 exhibited anti-tyrosinase activities, and compounds 3, 4 and 13 showed potential anti-inflammatory activities.
