Abstract:
Objective: To construct the fingerprint of the triterpenoic acid in Guizhi Fuling Capsule (GFC) by UPLC/Q-TOF-MS, and give a new method for its quality control. Methods: The triterpenoic acid were isolated by UPLC and detected by Q-TOF- MS. The established fingerprint was an atlas of UPLC/Q-TOF-MS. Results: The UPLC/Q-TOF-MS fingerprints of triterpenoids in GFC were established, which preserved high precision, selectivity, and specificity. A total of 26 common peaks were selected as the fingerprint peaks of GFC, of which a total of 18 mutual peaks (3, 5-18, 20, 23, and 24) from Poria, peak 2 was from Paeoniae Radix Alba and Moutan Cortex. Peak 4 was from Poria, Moutan Cortex, Paeoniae Radix Alba, and Cinnamomi Ramulus. Peak 19 was from Moutan Cortex, Paeoniae Radix Alba, and Cinnamomi Ramulus, peak 21 was from Moutan Cortex and Paeoniae Radix Alba, peaks 22 and 25 were from Poria, Moutan Cortex, Persicae Semen, Paeoniae Radix Alba, and Cinnamomi Ramulus, peak 26 was from Cinnamomi Ramulus, Paeoniae Radix Alba, and Persicae Semen. The similarity among the 10 batches of GFC was above 0.90. The Results: of validation met technical requirement of fingerprints. Sixteen chemical components were identified by UPLC-Q-TOF-MS, which were 16α-hydroxydehydrotrametenolic acid, 16α-hydroxychalcic acid, 3-oxo-6,16α-dihydroxy-lanosta-7,9(11),24(31)-trien-21- oic acid, dehydrotumulosic acid, tumulosic acid, 3-oxo-6,16α-dihydroxy-lanosta-8,24-diene-21-oic acid, eburicoic acid, polyporenic acid C, 3-epidehydrotumulosic acid, 3-O-acetyl-16α-hydroxydehydrotrametenolic acid, 3-epidehydropachymic acid, 3-O-acetyl-16α- hydroxyplugymic acid, dehydropachymic acid, pachymic acid, dehydrotrametenolic acid, and dehydroeburicoic acid. Conclusion: The method is rapid, accurate, and has desirable precision, reproducibility, and stability, which could be applied to the quality control of GFC.
