Profiling of chemical constituents of L. by UHPLC-Q-Orbitrap-HRMS and evaluation its anti-asthmatic activity.

L. is native to European countries and widely cultivated in China, especially in Xinjiang. It has been used in Uygur medicine for the treatment of cough caused by asthma.

Enhancing the in vitro release of total flavonoids extract from Dracocephalum moldavuca composite phospholipid liposomes optimized by response surface methodology.

The present study was undertaken to optimize the preparation conditions of total flavonoids extract from Dracocephalum Moldavuca composite phospholipid liposome (TFDMCPL) by response surface methodology (RSM) and to investigate the in vitro release (IVR) of TFDMCPL. Method of ethanol injection was adopted to prepare TFDMCPL. The single factor experiments were used for the key experimental factors and their test range.

Protective effects of acacetin isolated from Ziziphora clinopodioides Lam. (Xintahua) on neonatal rat cardiomyocytes.

Background: The total flavonoids from ethanol extract of the aerial part of Ziziphora clinopodioides Lam. (Lamlaceae) (Xintahua) showed protective activities against rat acute myocardial ischemia in rats. This study aims to isolate acacetin, a flavonoid, from the aerial part of Z.

[Optimization of extraction process for compund kaliziran gel with orthogonal design].

Objective: To optimize the extraction process of compund kaliziran gel.

Method: Orthogonal design was used to optimize the extracting process of eight herb medicines with the extract yield, the content of psoralen, isopsoralen and osthole as indexes, and to optimize the extracting process of Polygonum multflorumi and Seman sinapis albae with the extract yield and the content of 2,3,5,4'-tetrehydroxy-stilbene glucoside as indexes.

Result: The optimum extraction progress was as follows:eight herb medicines were extract 2 times for 1 hour with 8 times of 60% alcohol; P.
