Dynamic variations of bioactive compounds driven by enzymes in Psoralea corylifolia L. from growth to storage and processing

Bavachalcone and corylin are two major bioactive compounds isolated fromPsoralea corylifoliaL., which has been widely used as traditional Chinese medicine for many years. As two antibiotic or anticancer drugs, bavachalcone and corylin are used in combination with other drugs; thus it is necessary to evaluate potential pharmacokinetic herb-drug interactions (HDI) of the two bioactive compounds. The aim of the present study was to compare the effects of liver UDP-glucuronosyltransferase (UGT) 1A1, UGT1A3, UGT1A7, UGT1A8, UGT 1A10, and UGT2B4 inhibited by bavachalcone and corylin. 4-Methylumbelliferone (4-MU) was used as a nonspecific “probe” substrate. Bavachalcone had stronger inhibition on UGT1A1 and UGT1A7 than corylin which did not inhibit UGT1A1, UGT1A3, UGT1A7, UGT1A8, UGT1A10, and UGT2B4. Data fitting using Dixon and Lineweaver-Burk plots demonstrated the noncompetitive inhibition of bavachalcone against UGT1A1 and UGT1A7-mediated 4-MU glucuronidation reaction. The values of inhibition kinetic parameters (Ki) were 5.41 μM and 4.51 μM for UGT1A1 and UGT1A7, respectively. The results of present study suggested that there was a possibility of UGT1A1 and UGT1A7 inhibition-based herb-drug interaction associated with bavachalcone and provided the basis for further in vivo studies to investigate the HDI potential between bavachalcone and UGT substrates.

Psoralea corylifolia is the most important medicinal plant which has various secondary metabolites and its leaves are broadly used in many sectors due to its antimicrobial activity. This study aimed to find the bio-active compounds of chloroform extract of P. corylifolia leaves using Perkin-Elmer Gas Chromatography – Mass Spectrometry (GC-MS). The results of GC-MS compounds in the chloroform extract was appropriate to the database of National Institute of Standards and Technology (NIST). GC-MS analysis of chloroform extract of P. corylifolia leaves reveal the presence of bioactive compounds as Hexadecanoic acid, 3-hydroxy-, methyl ester , Hydroxylamine, O-decyl- , 2,4-Di-tert-butylphenol ) Cubenol , Neophytadiene , Phytol , Linoleic acid ethyl esterand 9,12,15-Octadecatrienoic acid, ethyl ester, (Z,Z,Z)- ) . These bio-active compounds are mainly responsible for various biological activities. Hence, this study will make a good way for the production of various products for curing various disease-causing pathogens by using P. corylifolia leaves.
