Two flavanones, 5,2',6'-trihydroxy-7,8-dimethoxyflavanone (1), 5,2',6'-trihydroxy-6,7,8-trimethoxyflavanone (2) and their 2'-O-β-D-glucosides (3, 4), and a neoclerodane-type diterpene, 15-demethoxyscupolin I (5), together with twenty-eight known compounds were isolated from the extracts of Lagochilus leiacanthus. The structures of the new compounds were determined by spectroscopic means. The two new flavanones and some known flavonoids showed the inhibitory activity on the release of β-hexosaminidase from RBL-2H3 cells.
