ABSTRACT
Ganoderma lucidum [Chizhi in Chinese] is one of the most valuable and widely used medicinal fungi in traditional Chinese medicines [TCMs]. Most of previous studies were focused on the triterpenoids and polysaccharides of G. lucidum, whereas less attention had been paid on the protein, which is another bioactive compound in it. In the present study, protein maps of fourteen G. lucidum samples were comprehensively analyzed by sodium dodecyl sulfate - polyacrylamide gel electrophoresis [SDS-PAGE] and two-dimensional electrophoresis [2-DE]. The results indicated that there were significant differences in protein profiles of G. lucidum samples from different origins. Furthermore, previous reported bioactive proteins from the fruiting bodies of G. lucidum, were mainly distributed in 4 taxa [A, B, C and D] based on their molecular weights on the 2-DE maps. The proteins should be considered as marker for the quality control of G. lucidum, because the proteomic variation may affect on their pharmacological activities
ABSTRACT
AIM To establish a UPLC-MS/MS combined with pattern recognition method for the simultaneous content determination of danshensu,protocatechuic acid,protocatechuic aldehyde,caffeic acid,rosmarinic,salvianolic acid B,salvianolic acid A,tanshinone Ⅰ,cryptotanshinone,tanshinone ⅡA and ursolic acid in Qishen Yiqi Dropping Pills (Astragali Radix,Salviae miltiorrhizae Radix et Rhizoma,Notoginseng Radix et Rhizoma,etc.).METHODS The analysis of 50％ methanol extract of this drug was performed on a 40 ℃ thermostatic ACQUITY UPLC(R) BEH C1s column (2.1 mm ×50 mm,1.8 μm),with the mobile phase comprising of acetonitrile-0.1％ formic acid flowing at 0.2 mL/min in a gradient elution manner.Then SIMCA14.0 software was adopted in the pattern recognition.RESULTS Eleven constituents showed good linear relationships within their own ranges (r ≥ 0.999 6),whose average recoveries were 98.45％-101.38％ with the RSDs of 1.70％-2.40％.The quality deviations of ten batches of samples were all within 2 std (standard deviation).CON CLUSION This simple,sensitive and accurate method can be used for the quality control of Qishen Yiqi Dropping Pills.
