ABSTRACT
OBJECTIVE To establish a quantitative analysis of multi-components by single marker (QAMS) method for simultaneous determination of 10 ganoderic acids in Ganoderma lucidum. METHODS Using ganoderic acid A as internal reference, high-performance liquid chromatography (HPLC) method was adopted to calculate relative correction factors of the other 9 components, such as ganoderic acid B, ganoderic acid C2, ganoderic acid D, ganoderic acid F, ganoderic acid H, ganoderenic acid A, ganoderenic acid B, ganoderenic acid C, ganoderenic acid D; the contents of above ganoderic acids were calculated with relative correction factors, and compared with the results of external standard method. RESULTS The linear relationship of ganoderic acid A, ganoderic acid B, ganoderic acid C2, ganoderic acid D, ganoderic acid F, ganoderic acid H, ganoderenic acid A, ganoderenic acid B, ganoderenic acid C and ganoderenic acid D were 0.032-3.996, 0.040-4.971, 0.037-4.568, 0.028-3.558, 0.033-4.177, 0.044-5.440, 0.032-3.944, 0.040-4.994, 0.045-5.593 and 0.035-4.342 mg/mL (all R 2≥0.999 2), respectively. RSDs of precision, stability (24 h) and reproducibility tests were all lower than 2%. Their average recovery rates were 99.43%, 100.25%, 98.50%, 99.88%, 100.59%, 99.64%, 98.50%, 99.40%, 99.64% and 99.76%, respectively (RSD<2%, n=6). Relative correction factors of ganoderic acid B, ganoderic acid C2, ganoderic acid D, ganoderic acid F, ganoderic acid H, ganoderenic acid A, ganoderenic acid B, ganoderenic acid C and ganoderenic acid D were 1.788 5, 1.288 2, 1.126 4, 1.698 5, 0.885 4, 5.468 1, 4.210 9, 5.780 8, 4.290 3, respectively. Relative errors between the content obtained by QAMS method and external standard method for G. lucidum from different origins were within ±12%. CONCLUSIONS It is feasible that the contents of 10 ganoderic acids are determined simultaneously by QAMS method, using ganoderic acid A as internal reference. This method shows good precision and reproducibility and can be used for the quality control of G. lucidum.
