Variation of 4 kinds of compounds in psoralea corylifolia processed by different methods was written by Song, Xiao;Qi, Aidi;Wang, Yuefei;Jing, Yakun;Chai, Xin;Liu, Yanan. And the article was included in Zhongguo Zhongyao Zazhi in 2011.Safety of (Z)-3-(6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)benzofuran-5-yl)acrylic acid This article mentions the following:

An efficient method for simultaneous quantification of 7 compounds belonging to 4 chem. types in Psoralea corylifolia processed by different methods was presented to elucidate variations of 4 kinds of compounds in different processed P. corylifolia. The chromatog. separation was performed on an ACUITY C18 column using acetonitrile and 0.1% formic acid aqueous solution in the gradient elution at 0.4 mL/min-1. Detection wavelength was set at 246 nm. Column temperature was fixed at 50°. The 4 kinds of compounds, including psoralenoside, isopsoralenoside (benzofuran glycosides), psoralen, isopsoralen, psoralidin (coumarins), bavachin (flavonoids), and bakuchiol (meroterpenes), were separated in 25 min. The correlation coefficients of those compounds were over 0.999 3 in the tested range. The intra-and inter-day precisions were below 1.5%. The average recoveries ranged from 99.2% to 106%. This method is simple, rapid, and accurate, which can be used for the determination of the 4 kinds of compounds in different processed P. corylifolia. In P. corylifolia processed by different methods, the contents of benzofuran glycosides, flavonoids, and meroterpenes in P. corylifolia processed by Leigong’s method are decreased obviously, while the contents of psoralen and isopsoralen are increased significantly. In the experiment, the researchers used many compounds, for example, (Z)-3-(6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)benzofuran-5-yl)acrylic acid (cas: 905954-17-8Safety of (Z)-3-(6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)benzofuran-5-yl)acrylic acid).
