Two new diterpenoids from cell cultures of Salvia miltiorrhiza.
A new spiroketallactone, epi-danshenspiroketallactone A (1) and a new C18-norditerpenoid, normiltioane (2) along with 21 known compounds, were isolated from cell cultures of Salvia miltiorrhiza. Their structures were elucidated on the basis of extensive spectroscopic analyses. In the in vitro assays, the compounds 9-11, 21-23 exhibited the significant antitumor activity with the IC(50) ranges o...
متن کاملNew diterpenoids from the aerial parts of Salvia reuterana
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...

متن کاملTwo new diterpenoids from Ballota limbata.
Two new clerodane-type diterpenoids trivially named as ballotenic acid (1) and ballodiolic acid (2) have been isolated from Ballota limbata along with three the known compounds; beta-amyrin, oleanolic acid, and beta-sitosterol. The structure elucidation of the new compounds was based primarily on two-dimensional (2D)-NMR techniques including correlation spectroscopy (COSY), heteronuclear multip...
متن کاملTwo new diterpenoids from Plectranthus nummularius Briq.
Two new antioxidative diterpenoids, plectranthol A (3)[19-O-(3,4-dihydroxybenzoyl)-11,12-dihydroxy-20(10-->5)-abeo-abieta-1(10),6,8,11,13-tetraene] and plectranthol B (4)[12-O-(3-methyl-2-butenoyl)-19-O-(3,4-dihydroxybenzoyl)-11-hydroxyabieta-8,11,13-trienel along with two known diterpenoids, parvifloron E (1) and F (2) were isolated from the leaves of Plectranthus nummularius Briq. Antioxidati...
