ABSTRACT
Triterpenoids are one of the most active constituents in Ligustri Lucidi Fructus, but only oleanolic acid has been mostly studied. In recent years, a growing number of studies have shown that other triterpenes from Ligustri Lucidi Fructus also have various biological activities, so it is necessary to build up a detailed profile of the triterpenoids in Ligustri Lucidi Fructus. The chromatographic separation was performed on a C_(18) column(4.6 mm×250 mm, 5 μm) with mobile phase of methanol-acetonitrile-0.2% formic acid for gradient elution. The detection wavelength was set at 210 nm, with a flow rate of 0.5 mL·min~(-1), and the column temperature of 25 ℃. The HPLC fingerprint of triterpenoids in Ligustri Lucidi Fructus was built by testing 21 batches of samples from different sources. The structures of the total 15 common chromatographic peaks were elucidated with UHPLC-ESI-Orbitrap-MS/MS technique and six of them were identified as tormentic acid, pomolic acid, maslinic acid, botulin, oleanolic acid and ursolic acid by comparison to the reference substances. Under the same chromatographic condition, four main triterpenes(podocarboxylic acid, hawthorn acid, oleanolic acid and ursolic acid) were quantified and the results of system adaptability and methodology investigation all met the requirements of content determination. Meanwhile, with oleanolic acid(A) as the internal reference substance, quantitative analysis of multi-components by single marker(QAMS) method was used to analyze the above four components. The relative correction factor of oleanolic acid(B), hawthorn acid(C) and ursolic acid(D) to oleanolic acid was f_(B/A)=1.12, f_(C/A)=1.02 and f_(D/A)=0.88, respectively, and the relative retention values of these three to oleanolic acid was RRV_(B/A)=0.46, RRV_(C/A)=0.70 and RRV_(D/A)=1.03, respectively. The contents determined by two methods were similar. In conclusion, the method built in this paper is proved to be simple, reliable and specific for the simultaneous qualitative and quantitative analysis of the triterpenoids in Ligustri Lucidi Fructus, which can lay foundation for further assays of the triterpenoids in Ligustri Lucidi Fructus and the relative products.
