Constituents of the whole herb of Clinoponium laxiflorum

The isolation and identification of twenty-two components (including one ne w compound) from the whole herb of Clinoponium laxiflorum (Hay) Matsum (Lab iatae) are described. Their structures were determined on the basis of spec tral and chemical transformation. One new compound is methyl rosmarinate. T he other twenty-one compounds include three steroids (alpha-spinasterol, al pha-spinasteryl-3-O-beta-D-glucopyranoside, and beta-sitosteryl-3-O-beta-gl ucopyranoside), three triterpenes (oleanolic acid, ursolic acid, and betuli nic acid), nine flavonoids (didymin, apigenin-7-O-beta-glucopyranoside, lut eolin-7-O-beta-glucopyranoside, isosakuranetin, narigenin, apigenin, luteol in, narirutin, and hesperidin), three lignolic acids (rosmarinic acid, 3-(3 ,4-dihydroxyphenyl)lactic acid, and caffeic acid), and three phenols (4-hyd roxybenzaldehyde, 3,4-dihydroxybenzaldehyde, and 3,4-dihydroxybenzoic acid) .
