[Exploration of emulsifying material basis of Angelicae Sinensis Radix volatile oil based on partial least squares and hydrophile-lipophile balance value].

This study explores the emulsifying material basis of Angelicae Sinensis Radix volatile oil (ASRVO) based on partial least squares (PLS) method and hydrophile-lipophile balance (HLB) value.The turbidity of ASRVO emulsion samples from Gansu,Yunnan,and Qinghai was determined and the chemical components in the emulsion were analyzed by GC-MS.The PLS model was established with the chemical components as the independent variable and the turbidity as the dependent variable and evaluated with indexes R~2X and R~2Y.

[Research progress on antibacterial activity of herbal volatile oil].

Due to worldwide abuse of chemical antibiotics and continuous emergence of "superbugs", the harm of bacterial drug resistance to human beings has become more and more serious. Therefore, it is of great significance to look for green antibiotics with a wide range of sources, broad antibacterial spectrum, non-toxicity or low toxicity, environmentally friendliness, diverse active components and low drug resistance. The volatile oil of traditional Chinese medicine is a kind of volatile oily liquid that exists in plants and can be distilled with steam and immiscible with water.

[Mechanism of Aurantii Fructus Immaturus volatile oil in treatment of slow transit constipation based on network pharmacology].

To construct the active component-action target network diagram and protein-protein interaction(PPI) network diagram of Aurantii Fructus Immaturus volatile oil, so as to explore the mechanism of Aurantii Fructus Immaturus volatile oil in the treatment of slow transit constipation(STC) by analyzing the functions and pathways involved in the target. The chemical constituents of Aurantii Fructus Immaturus volatile oil were determined by gas chromatography-mass spectrometry(GC-MS). The targets of Aurantii Fructus Immaturus volatile oil were studied by PubChem, TCMSP, STITCH and Swiss Target Prediction.
