[Quality evaluation of Rhei Radix et Rhizoma decoction].

Decoction of single medicinal herb is a reference for the standardization of different dosage forms of Chinese medicine and it provides a new direction for solving the problems existing in the quality of Chinese medicinal granules such as no uniform dosage form and no clear quality standard. In this paper, the quality evaluation method of standard decoction of rhubarb was established to provide reference for the quality control of common dosage forms such as clinical decoction and formula granule. 10 batches of representative Rhei Radix et Rhizoma were collected to establish UPLC fingerprints were established.

[Establish quality evaluation system for standard Ephedrae Herba decoction].

To establish the quality control methods for the standard decoction of Ephedrae Herba, and provide the reference for quality evaluation method of all Chinese herbal medicine decoction.Standard decoction of Ephedrae Herba was prepared, and UPLC-UV fingerprint was established to determine the total contents of ephedrine and pseudoephedrine. Then UPLC-QTOF/MS was used to confirm the major common peaks in the fingerprint to clarify the main chemical constituents in the decoction.

[Establish quality evaluation method based on standard decoction of Danshen extract].

The quality of Danshen extract granules on market is largely different from each other mainly due to the heterogeneous quality of raw materials of Salvia miltiorrhiza, various producing procedures and lack of good quality evaluation method. Formula granule and "standard decoction" have the same quality. In this paper, a systematic evaluation method for the quality of Danshen decoction was established from the perspective of "standard decoction", in order to explore the main factors affecting the quality uniformity of Danshen extract granules.

[Quality evaluation of decoction of single medicinal herb--a case of Lonicerae Japinicae Flos].

Decoction of single medicinal herb is a reference for the standardization of different dosage form of Chinese medicine and it provides a new direction for solving the problems existing in the quality of Chinese medicinal granules such no uniform dosage forms and no clear quality standard. There are few reports on the idea, method and preparation of single herb standard decoction. Our country is in urgent need of that information in order to improve the consistency and stability of traditional Chinese medicine products.

Serum and Brain Metabolomic Variations Reveal Perturbation of Sleep Deprivation on Rats and Ameliorate Effect of Total Ginsenoside Treatment.

Sleep loss or sleep deprivation (SD) refers to shorter sleep than average baseline need, and SD has been a serious problem of modern societies which affects health and well-being. is a well-known traditional Chinese medicine (TCM). Our previous study has demonstrated that total ginsenosides (GS), the extracts from , could effectively improve cognition and behavior on SD rats.

[Qualitative analysis of chemical constituents in Si-Wu Decoction based on TCM component database].

In order to clarify the chemical constituents of Si-Wu Decoction rapidly and holistically, we analyzed the ethanol extract of Si-Wu Decoction by UPLC/Q-TOF-MSE and UNIFI which based on traditional Chinese medicine database, the probable structures of 113 compounds were identified. The results show that this method can rapidly and effectively characterize the chemical compounds of Si-Wu Decoction and provide a new solution for identification of components from complex TCM extract.

Screening antitumor bioactive fraction from Sauromatum giganteum (Engl.) Cusimano & Hett and sensitive cell lines with the serum pharmacology method and identification by UPLC-TOF-MS.

Sauromatum giganteum (Engl.) Cusimano & Hett Tuber are used in Chinese folklore medicine for treatment of neoplasms. However, the claim has not been scientifically validated.

[Study on effects of baicalin, berberine and Astragalus polysaccharides and their combinative effects on aldose reductase in vitro].

Objective: To observe the activities of baicalin, berberine and Astragalus polysaccharides and their combinative effects on aldose reductase (AR) by a screening model of aldose reductase inhibitor (ARI) in vitro.

Methods: The inhibition of AR by baicalin, berberine and Astragalus polysaccharides and positive drug (Epalrestat) in different concentrations were evaluated, and their combinative effects were studied according to orthogonal t design.

Results: Baicalin and berberine had remarkable inhibitory effects on AR, the inhibitory rates were (88.
