THE CHEMICAL CONSTITUENTS OF COLEUS ESQUIROLII(II)

Laboratory of Phytochemistry, Kunming Instiute of Botany, Academia Sinica, Kunming 650204

Received Date: 7 September 1990

Three new diterpenoids, named esquirolin B (1), C (2), D (3) respectively, and two known cemocunds-eariocal (4) and taraxerol were isolated from Coleus esquirolii (Levl). The structure elucidation was achieved by spectroscopic means.
