New polyhydroxylated triterpenes and anti-inflammatory activity of Salvia hierosolymitana.
Salvia hierosolymitana (Lamiaceae) leaves were investigated for their topical anti-inflammatory properties following a bioassay-guided fractionation. The chloroform extract showed a strong inhibition of the Croton oil-induced ear oedema in mice, comparable to that of indomethacin. Phytochemical and pharmacological investigations of this extract led to the isolation of eight anti-inflammatory polyhydroxylated triterpenes of the ursane and oleanane series. Four of them are new compounds, whose structures were elucidated by NMR and mass spectroscopy as 3beta, 6alpha,23-trihydroxyurs-12,19(29)-dien-28-oic acid, 23-( TRANS-P-coumaroyloxy)-3beta, 6alpha,30-trihydroxyurs-12-en-28-oic acid, 2alpha,3beta-dihydroxyolean-28-oic acid and 24-nor-2alpha,3beta-dihydroxyolean-4(23),12-ene.
