Abstract
AIM:To isolate labdane diterpenoids from the roots of Coleus forskohlii and to elucidate the structures of them.METHOD:The chemical constituents were isolated by various column chromatographic analyses.The structures were elucidated on the basis of IR,MS, 1H NMR , 13 C NMR and 2DNMR experiments.RESULT: Seven diterpenoids were obtained and the structures were identified as 6-acetoxyforskolin(1),1,6-diacetoxy-7-deacetoxyforskolin (2),1,6-diacetoxy-9-deoxyforskolin(3),6-acetoxy-7 -deacetoxyforskolin(4),forskolin G(5),forskolin H(6) and 6β-hydroxy-8,13-epoxylabd -14-ene-11-one(7).CONCLUSION:Compounds 1~3 are new natural products.
