Triterpenes from Paliurus hemsleyanus

Separation of the water-insoluble fraction of the ethanol extract from the root of Paliurus hemsleyanus led to the isolation of three new triterpenes. They are ceanothic acid derivatives named zizyberenalic acid ceanothanolic acid and 2-O-(p-coumaroyl)-ceanothanolic acid. Additional NMR data for the known colubrinic acid and euscaphic acid, the latter being characterized as methyl ester, were also assigned.

Triterpenoids and other compounds from Salvia roborowskii Maxim

Two new triterpenoids, 2α-hydroxy-3β-methoxyurs-12-en-28-oic acid and 3α-hydroxy-2α-methoxyurs-12-en-28-oic acid as well as 25 known compounds were isolated from the whole plant of Salvia roborowskii Maxim. Their structures were elucidated by means of spectral data and chemical transformation. This is the first report on the chemical constituents of this plant. The presence of eugenyl β-D-glucopyranoside 22 in a plant of the genus Salvia is also reported for the first time.
