Abstract: | Most of the Ganoderma lingzhi medicinal preparations use water extract of fruiting bodies as raw materials. In order to quickly and accurately determine the content of triterpenes in the water extract of G. lingzhi fruiting bodies and related products, a HPLC analysis method with good separation effect is established. Through optimizing the chromatographic column and elution conditions, the Agilent Zorbax SB-Aq C18 chromatographic column (250 mm× 4.6 mm, 5 μm) was selected. Using acetonitrile-glacial acetic acid aqueous solution (0.01%) as mobile phase gradient, under the flow rate of 1.0 mL/min, detection wavelength of 252 nm, and column temperature of 30 °C, 10 ganoderic acids such as ganoderic acid A and ganoderic acid F are well separated. Methodological investigations show that the precision, repeatability, stability, and sample recovery of this analytical method are all less than 5%. This method can be used for quantitative detection of 10 types of ganoderic acids including ganoderic acid C2, ganoderic acid G, ganoderenic acid B, and ganoderic acid B. Comparative analysis of 10 triterpenoids in the raw fruiting bodies, water extracts of fruiting bodies and commercial end products of G. lingzhi indicates that the water extracts of G. lingzhi fruiting bodies contain all of these 10 triterpenes, and the content is 2.52%-6.83% being higher than that in raw fruiting bodies. The triterpene content in the commercial end G. lingzhi products is 0.27%-0.84%. This method advantages the establishment of quality standard of G. lingzhi water extract and its products. |
