Fourp-coumaroylated sesquiterpenoids were isolated from Pilea cavaleriei. Three of them are new compounds. Compounds 2 and 4 showed antimycobacterial activity against Mycobacterium tuberculosis H(37)Rv.
Fourp-coumaroylated sesquiterpenoids (1-4), including three new ones (1,2, and 4), were isolated from the whole plants ofPilea cavaleriei. Their structures were established on the basis of comprehensive spectroscopic analysis and comparison with data reported in the literature. Compounds 1-4 were evaluated for their antimycobacterial activities, and 2 and 4 were active againstMycobacterium tuberculosis H(37)Rv with the MIC values of 19.6 +/- 0.19 and 17.4 +/- 0.12 mu g/mL, respectively.
