摘要
A new lycopodine alkaloid, 15 alpha-methyllycopodane-5 beta,6 beta-diol N-oxide (1), was isolated from the whole plants of Phlegmariurus yumumensis CHING, together with the two known alkaloids 15 alpha-methyllycopodane-5 beta,6 beta-diol (2) and lycoposerramine H (3), and four serratene-type triterpenoids, serratenediol-3-acetate (4), serratenediol (5), lycocryptol (6), and serratriol (7). Their structures were elucidated on the basis of spectroscopic analyses, including HR-ESI-MS, (1)H- and (13)C-NMR, DEPT, (1)H,(1)H-COSY, HSQC, HMBC, and NOESY.
