Abstract
Fructus Gleditsiae abnormalis and Fructus Gleditsiae sinensis are widely used in traditional Chinese medicine. As different developmental stages of fruits of the same plant Gleditsia sinensis Lam., whether Fructus Gleditsiae sinensis can be used as the substitute of Fructus Gleditsiae abnormalis has long been debated. To compare the differences of the content of main active saponins between the two fruits, we established a new LC-ELSD method for simultaneous determination of four major saponins present in two fruits. After fully validated, the method was successfully applied to quantitatively analyze the four bioactive saponins of twenty samples, 11 of Fructus Gleditsiae abnormalis and 9 of Fructus Gleditsiae sinensis obtained from different locations. It was shown that there were no significant differences in saponins contents and LC profiles between the two fruits. Moreover, the developed method can be used for quality control of Fructus Gleditsiae abnormalis and Fructus Gleditsiae sinensis.
