Study on Chemical Constituents of the Commiphora mukul

Objective:To study Chemical Constituents ofCommiphora mukul.Methods:Compounds were separated by various column chromatography methods include:silica gel(CC),ODS(CC) and preparative HPLC,et al.The structure was identified by the basis of modern spectroscopic methods.Results:Four compounds were obtained and identified as Epi-magnolin(1)、1,7,8,10,11,12,13,14,15,17-decahhyro-17-decahhyro-17-(S)-1-hhyroxyethyl-10,13-dimethyl-2H-cyclopenta[α]phenanthrene-3,16(16H,9H)-dione(2)、1,7,8,10,11,12,13,15,16,17-decahhyro-17-(2-hhyroxy-6-methylheptan-2-yl)-10,13-dimethyl-2H-cyclopenta[α]phenanthrene-3(6H,9H,14H)-one(3)、20-methoxy-4,17(20)Z-pregnadiene-3,16-dione(4). Conclusion:Compounds 1-3 were isolated from Burscraccaefor the first time,compounds 4 was isolated fromCommiphora mukulfor the first time.
