Abstract: Two diterpcnoids were isolated from the leaves of Rabdosia calcicolus var. subcaluus Hand. -Mazz. Weisiensin A is a known compound, its structure should be co-rrected to 3(3, 6a-dihydroxy-la, 7(3, llp"triacetoxy-ent-kaur-16-cn~15-onc by spectro-scopic and chemical evidences. Calcicolin A is a new diterpenoid, its structure was esta-blished as 3(3-hydroxy-lcc,6a,7[3, ll|3-tetraacetoxy-ent-kaur-16-cn-15-one ( 1 ) on the basis of spectral data.

Key words: Rabdosia calcicolus var. subcalvus
