ABSTRACT
In this study, ultra-performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS~E) was used to analyze the plasma components of Danzhi Xiaoyao Formula after oral administration. Forty-nine plasma components were found in the serum of rats by comparing the compound extract, drug-containing serum, and blank serum. Components, such as 6-hydroxycoumarin, poricoic acid F, deoxoglabrolide, 30-norhederagenin, kanzonol R, 3',6'-di-O-galloylpaeoniflorin, 16α-hydroxytrametenolic acid, 16-deoxyporicoic acid B, 3-O-acetyl-16α-hydroxytrametenolic acid, and 16α,25-dihydroxydehydroeburiconic acid, were first found in rat serum. Behavioral tests, including the tail suspension test, novel object recognition test, and novelty-suppressed feeding test, were conducted for behavioral analysis. It was confirmed that this formula had therapeutic effects on perimenopausal depression. Furthermore, in combination with the network pharmacology method, 53 core targets including MAPK1, HRAS, AKT1, EGFR, and ESR1 were screened, and these targets participated in 165 signaling pathways, including PI3K-AKT, AMPK, VEGFA, MAPK, and HIF-1. In summary, the potential effects of Danzhi Xiaoyao Formula in treating perimenopausal depression are associated with mechanisms in accelerating inflammation repair, improving neuroplasticity, affecting neurotransmitters, regulating estrogen levels, and promoting new blood vessel formation.

In order to clarify the main chemical constituents of Huangdi Anxiao Capsules, an ultra-high performance liquid coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS~E) combined with Waters UNIFI software were successfully used to rapidly identify the chemical constituents in Huangdi Anxiao Capsules. The mass spectrometry data of chemical constituents from Huangdi Anxiao Capsules were collected by UPLC-Q-TOF-MS~E, and their structures were identified by the results of UNIFI software according to relative retention time of reference standards, MS feature fragments and literature data of each compound. A total of 100 compounds in Huangdi Anxiao Capsules were identified, including 25 compounds from Pueraria Lobate Radix, 22 compounds from Coptis Rhizoma, 6 compounds from Ophiopogonis Radix, 14 compounds from Eriobotryae Folium, 22 compounds from Rehmanniae Radix, and 15 compounds from Notoginseng Radix et Rhizoma. Among them, 3 compounds were common components. These 100 compounds included flavonoids, alkaloids, saponins and organic acids. This study systematically analyzed the chemical composition of Huangdi Anxiao Capsules, so as to provide evidences for defining the chemical material basis of Huangdi Anxiao Capsules.

UPLC-Q-TOF-MS was used to analyze the chemical differences in Bupleurum. chinense,B. marginatum,B. marginatum var. stenophyllum and B. smithii var. parvifolium. Chromatographic separation was carried out on an Acquity HSS T3 C_(18) column( 2. 1 mm ×100 mm,1. 8 μm,Waters) with the mobile phase composed of 0. 1% formic acid in water-acetonitrile in the gradient elution. A hybrid quadrupole time-of-flight tandem mass spectrometry( Q-TOF-MS~E) was used for mass spectrometric analysis. Finally,25 peaks were identified based on their exact mass data and fragmentation characteristics. B.chinense,B.marginatum,B. marginatum var. stenophyllum and B. smithii var. parvifolium were obviously clustered into 3 types through processing by principal component analysis( PCA). There was almost no difference between B. chinense and B. marginatum. However,the compounds existed in B. chinense were different from those in B. marginatum var. stenophyllum,and B. smithii var. parvifolium.
