[Studies on the chemical constituents of Lagotis yunnanensis (II)].

To study the chemical constituents of Lagotis yunnanensis W. W. Smith. Compounds were isolated from the ethanolic extract of the title herb by silica gel column chromatography, and their structures were identified by physical and chemical evidences and spectral methods. Seven compounds were isolated and identified as artselaeroside A (1),3-hydroxy-5-methoxy-benzyl alcohol (2), tyrosol (3), glycerin-9'-Z-octadecaenate (4), glycerin-docosanate (5), glycerin-tetracosanate (6), tetracosanoic acid (7), respectively. All the compounds were isolated from this plant for the first time.
