| Abstract: | Ganoderic acids (GAs) are oxygenated lanostane-type triterpenoids from the traditional medicinal mushroom Ganoderma lucidum and of significant biological activities. Although a ganoderic acid 3-hydroxy-lanosta-8,24-dien-26-oic acid (HLDOA) was found to be biosynthesized from lanosterol, further post-modification of HLDOA is yet unclear. In this work, by using HLDOA as the substrate and a crude enzyme from G. lucidum as the biocatalyst, we observed a new peak in liquid chromatography from the reaction system. The product was purified and identified to be 3-oxo-lanosta-8,24-dien-26-oic acid (OLDOA), which may be converted from HLDOA by a putative dehydrogenase of G. lucidum. The work is useful to future manufacture of GAs as well as their biosynthetic pathway elucidation. |
