Three new guaiane type sesquiterpenes were isolated from the methanolic extract of the fruits of Torilis japonica together with a known compound, torilin (1). Their structures were established as 11-acetoxy-8-isobutyryl-4-guaien-3-one (2), 11-acetoxy-8-methacrylyl-4-guaien-3-one (3), and 11-acetoxy-8-propionyl-4-guaien-3-one (4) by spectroscopic methods. These compounds inhibited lipopolysaccha...

A known ent-kaurane diterpenoid, ent-19-al-17,16β-dihydroxykaurane (1), together with the new one, ent-3β, 16β, 19-trihydroxykaurane (2), called leptophyllin, were isolated from aerial parts of Baccharis leptophylla. Their structures were established on the basis of NMR spectroscopic analysis. Based on this study the H and C NMR spectral data of compound (1) were completed by means of 2D NMR te...

The organic soluble extract from the leaves of the native North American prairie plant Ipomoea leptophylla (big root morning glory) showed in vitro activity against M. tuberculosis. Bioassay-guided fractionation of this extract resulted in the identification of two new resin glycosides (6, 7). Base-catalyzed hydrolysis of these glycosides gave operculinic acid (1) as the glycosidic acid compone...
