Two serratane triterpenes from the stem bark of Picea jezoensis var. hondoensis
摘要:
Two serratane triterpenoids were isolated from the stem bark of Picea jezoenis var. hondoensis, together with two known compounds, 3 beta-methoxyserrat-14-en-21-one and 3 beta-methoxyserrat-14-en-21 alpha-ol. The serratane triterpenoids were characterized as 14 beta,15 beta-epoxy-3 alpha-methoxyserratan-21 beta-ol and 3 alpha-methoxy-21 beta-hydroxyserrat-14-en-16-one, on the basis of chemical and spectroscopic evidence; (C) 1999 Elsevier Science Ltd.
