Structure of phyllostachysin A: novel antineoplastic diterpenoid from Rabdosia phyllostachys
Abstract
A new antineoplastic diterpenoid of novel structure, phyllostachysin A, was isolated from the leaves of Rabdosia phyllostachys(Diels) Hara (Labiatae) and the structure has been shown to be that in the structure (1) from spectral and chemical evidence.
