Development of RP HPLC‐PDA method for simultaneous quantitative analysis of Inoscavin A and Meshimakobnol A and application on some Phellinus mushroom species

Abstract

Abstract Phellinus igniarius, a medicinal mushroom containing many active ingredients with health benefits, can be applied in functional food. At present, the quantification of the main active ingredients from higher fungi (Ganoderma, Phellinus…) materials from different growing sources is a mandatory requirement to standardize the input resources of pharmaceutical and food production. Our study's aims are to perfect the RP HPLC‐PDA method for quantitative analysis of Inoscavin A and Meshimakobnol A which are two main active ingredients present in Phellinus mushroom. In this analytical method, a C18‐HPLC column and the mixture of methanol and formic acid solutions (pH = 2.2) are used to analyze and elute the active substances with the column activity parameters being the concentration gradient. This perfect method was tested for system suitability, repeatability, intermediate precision, recovery, and linear curve calibration to validate the method. After validation, the perfected RP HPLC‐PDA method was applied to analyze eight samples of Phellinus and three samples of Ganoderma mushroom category. This method can be the basis for classifying between Phellinus and some other medicinal mushrooms.
