The isolation and identification of twenty-two components (including one new compound) from the whole herb of Clinoponium laxiflorum (Hay) Matsum (Labiatae) are described. Their structures were determined on the basis of spectral and chemical transformation. One new compound is methyl rosmarinate. The other twenty-one compounds include three steroids (alpha-spinasterol, alpha-spinasteryl-3-O-beta-D-glucopyranoside, and beta-sitosteryl-3-O-beta-glucopyranoside), three triterpenes (oleanolic acid, ursolic acid, and betulinic acid), nine flavonoids (didymin, apigenin-7-O-beta-glucopyranoside, luteolin-7-O-beta-glucopyranoside, isosakuranetin, narigenin, apigenin, luteolin, narirutin, and hesperidin), three lignolic acids (rosmarinic acid, 3-(3,4-dihydroxyphenyl)lactic acid, and caffeic acid), and three phenols (4-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, and 3,4-dihydroxybenzoic acid).
