PROCESS FOR THE ISOLATION OF CALLITERPENONE (16ALPHA, 17-DIHYDROXY-3-OXO-PHYLLOCLADANE)

摘要

The invention provides a process for the isolation of calliterpenone (16.alpha., 17dihydroxy-3-oxo phyllocladane), which is a phyllocladane diterpenoid with plant growth regulating properties, from the plant Callicarpa macrophylla. The process of the invention isolates the calliterpenone using an organic solvent to increase yield.
