Pseudolarolides O (1) and P (2), two novel triterpenoids with a cycloartane-type framework, were isolated from the seeds of Pseudolarix kaempferi Gord. (Pinaceae). Their structures were elucidated as (16R,23S,25R)-16,23-epoxy-3,4 : 9,10-disecocycloartan-1(10),9(11)-diene-3(4),26(23)-diolide (1), and (9S,16R,23S,25R)-1,9 : 16,23-diepoxy-8,9 : 9,10-disecocycloartan-1(29),5(6),10(19)-triene-3(4),26(23)-diolide (2), respectively, on the basis of spectroscopic techniques and X-ray-diffraction… Expand
