Including eleven alkaloids, dihydroquercetin (1), corydaline (2), tetrandrine (3), isoorientin (4), corydaline 5, 4, 6, 6, 7, 7, 12, 12 and 12, two anthraquinones (11) and emodin (9) and emodin methyl ether (10); one triterpene compound, namely 3β-hydroxy- oleanane-111,3 (18) -diene-28- 3 sterols, stigmasterol (15), β-sitosterol (16) and daucosterol (17). Among them, compounds 9 ~ 11 were isolated from this genus for the first time, 1 were isolated from this species for the first time.
