Abstract
AbstractGanoderic acids (GAs) and lucidenic acids (LAs) are the two specific triterpene compositions of Ganoderma lucidum. The HPLC fingerprint profile of GAs has been well‐established, but the reports for LAs were rare. In this study, six new lucidenic acids: H2 (1), H3 (2), I2 (3), I3 (4), K (5), L (6) and nine known compounds: lucidenic acids A (7), B (8), C (9), D2 (10), E2 (11), F (12), N (13), P (14), Q (15), were isolated from a strain of G. lucidum fruiting body (YK‐02). A specific fingerprint of the lucidenic acid type (LA‐type) HPLC spectrum comprised of these triterpenes was revealed for the first time. The HPLC spectra of four strains of G. lucidum were investigated and showed identical profiles with the typical ganoderic acid type (GA‐type, strains YK‐01 and BCRC36065) and lucidenic acid type spectra (strains YK‐02 and BCRC36090). The fingerprint profiles can be used in both species and strain identification of G. lucidum. Quantitation of lucidenic acid A by using HPLC was also validated.
