Abstract
New triterpenoid-tetra-ols, lycocryptol, 21-epilycocryptol, and diepilycocryptol, isolated from various Lycopodium plants were shown to be serrat-14-en-3β, 21α, 24, 30-tetraol (1a), serrat-14-en-3β, 21β, 24, 30-tetraol (2a), and serrat-14-en-3α, 21β, 24, 30-tetraol (3a) respectively, by spectral and chemical means. Two new acids, lycernuic acid-A and -B which were isolated from L. cernuum were settled to be 3β, 21β-dihydroxyserrat-14-en-24-oic acid (14a) and 3β, 21β, 30-trihydroxyserrat-14-en-24-oic acid (15a) by correlating them to 21-episerratriol and 21-epilycocryptol respectively.
