Abstract：OBJECTIVE To carry out HPTLC and HPLC fingerprint analysis of 18 batches of Ganoderma samples using two kinds of reference substance of Ganoderma extract, G. lucidum Extract Reference Substance(CZERS) and G. sinense Extract Reference Substance(ZZERS). METHODS HPTLC Fingerprint was used to analyze triterpene acids and sterols in Ganoderma with chloroform-acetonitrile-methanol-formic acid (13∶2∶0.5∶0.5, develop 3 times) and cyclohexane-ethyl acetate-methanol-formic acid (15∶5∶0.5∶0.5, develop 2 times) respectively. HPLC Fingerprint analysis was conducted using Kromasil 100-5 C18 column (4.6 mm×250 mm, 5 μm) kept at 25 ℃. Mobile phase A was acetonitrile and B was 0.02% phosphoric acid; gradient elution procedure was as follows: 0-40 min, 29%→33% A; 40-70 min, 33%→65%A; 70-105 min, 65%→100%A; 105-120 min, 100% A; flow rate was 1.0 mL·min-1. DAD detector was adopted with detection wavelength set at 244 nm. The injection volume was 10 μL. RESULTS By using ERS and fingerprint analysis, G. lucidum, G. sessile and G. lucidum could be distinguished. The components of G. lucidum in different species and growth patterns were different. CONCLUSION There are many varieties of G. lucidum, which can be divided into wild and artificial cultures, and the culture media of artificial culture are different, which leads to the difference of individual components of different G. lucidum. Fingerprint analysis based on ERS of specific varieties are more suitable for the overall quality control of G. lucidum.
