Ethyl rosmarinate (RAE) is one of the active constituents from (Benth.) O. Kuntze, which is used for diabetic treatment in Chinese folk medicine.

A new triterpenoid saponin from Clinopodium chinense (Benth.) O. Kuntze.

A new triterpene saponin, 3β,16β,23α,28β,30β-pentahydroxyl-olean-11,13(18)-dien-3β-yl-[β-D-glucopyranosyl-(1→2)]-[β-D-glucopyranosyl-(1→3)]-β-D-fucopyranoside, was named Clinoposaponin D (1), together with six known triterpene saponins, buddlejasaponin IVb (2), buddlejasaponin IVa (3), buddlejasaponin IV (4), clinopodisides D (5), 11α,16β,23,28-Tetrahydroxyolean-12-en-3β-yl-[β-D-glucopyranosyl-(1→2)]-[β-D-glucopyranosyl-(1→3)]-β-D-fucopyranoside (6) and prosaikogenin A (7), and two known triterpenes, saikogenin A (8) and saikogenin F (9) were isolated from Clinopodium chinense (Benth.) O. Kuntze.

Diterpenoids from Saliva plebeia R. Br. and Their Antioxidant and Anti-Inflammatory Activities.

A new skeleton of diterpenoid, 1,2,3,4,4α,9,10,10α-octahydro-(4α-hydroxyymethyl) -1,1-dimethyl-9-(1-methylethyl)-(2S,3S,4αR,9R,10αS)-2,3,5,7-phenanthrenetertrol, named plebeianiol A (1), along with four known diterpenoids (2-5), were isolated from Salvia plebeia R. Br. Their structures were determined on the basis of spectral analysis.
