A new prenylated naphthoquinoid, named (3R,4aR,10bR)-3,10-dihydroxy-2,2-dimethyl-3,4,4a,10b-tetrahydro-2H-naphtho[1,2-b]-pyran-5H-6-one (1), was isolated from the aerial parts of Clinopodium chinense (Benth.) O. Kuntze, together with six known compounds: apigenin (2), luteolin (3), neoeriocitrin (4), naringenin (5), narirutin (6), and didymin (7).(More)
A new abietane diterpene, named as 3β-hydroxy-12-O-β-D-glucopyranosyl-8,11,13-abietatrien-7-one (1), together with four known flavonoids, was isolated from the hot water extract of the aerial parts of Clinopodium chinense. Their structures were determined by analysing the spectroscopic data including 1D, 2D NMR and HR-ESI-MS. Compound 1 tested against(More)
Three new triterpene saponins, named Clinoposaponin A, Clinoposaponin B, and Clinoposaponin C along with three known triterpene saponins were isolated from the Tabellae Clinopodii. The structures of these compounds were elucidated by means of various spectroscopic analyses. All of the isolated compounds were tested against Hela, HCT-8, AGS, and MCF-7 human(More)
