Extraction Process of Zhuang Medicine Fumigation Lotion

[Objectives]To establish the extraction process and quality standard method of Zhuang medicine fumigation lotion.[Methods]The orthogonal design method was employed to optimize the water extraction process with the amount of water added,decocting time and extraction times as factors,and syringin content and dry extract yield as indexes.The content of syringin was determined by high performance liquid chromatography.[Results]The best water extraction process was:soaking in water for 1 h,decocting twice,added 10 times the amount of water each time,decocting for 1 h.The average content of syringin in 3 batches was 0.98 mg/g,and the average dry extract yield was 26.07%.[Conclusions]The project adopts water extraction method to prepare Zhuang medicine fumigation lotion,which has the characteristics of high efficiency and suitable for large-scale production.The quality control method is reliable,rapid and accurate,and can effectively control the quality of the lotion.

Effects of Dachengqi Decoctions Made from Raw Rhubarb and Vinegar-processed Rhubarb on Levels of Endotoxin,NO and TNF-αin Serum

[Objectives]The effects of Dachengqi decoctions made from raw rhubarb and vinegar-processed rhubarb on serum endotoxin,NO and TNF-αlevels were investigated.[Methods]Total 105 mice were randomly divided into Dachengqi decoction made from raw rhubarb groups(6,10 g/kg),Dachengqi decoction made from vinegar-processed rhubarb groups(6,10 g/kg),positive control group,blank control group and model group.After administration at a dose of 20 mL/kg,the levels of endotoxin,NO and TNF-αin serum were determined.The effects of Dachengqi decoctions made from raw rhubarb and vinegar-processed rhubarb on serum endotoxin,NO and TNF-αlevels in mice were compared.[Results]Dachengqi decoctions made from raw rhubarb and vinegar-processed rhubarb both increased the NO level and reduced the endotoxin and TNF-αlevels in serum of ABP mice.[Conclusions]Dachengqi decoctions made from raw rhubarb and vinegar-processed rhubarb have different effects on endotoxin,NO and TNF-αcontents.These changes correspond to the effects of Dachengqi Decoctions made from raw rhubarb and vinegar-processed rhubarb.The change in the content of rhubarb anthraquinones has a certain effect on the efficacy of Dachengqi decoction.

Preliminary Study and Quality Analysis of Laggera alata

[Objectives]To establish a method for quality analysis of Laggera alata.[Methods]The water content,total ash and alcohol-soluble extract of Laggera alata were determined according to the method of 2015 edition of Chinese Pharmacopoeia.[Results]Ten batches of Laggera alata from different producing areas and different collection time in Guangxi had the same plant morphology and medicinal properties.The experimental results were as follows:the water content was 5.19%-10.86%;the total ash content was 5.91%-10.74%;the acid-insoluble ash content was 0.44%-0.92%;the extract content was 14.64%-19.95%.[Conclusions]The experimental results can provide scientific basis for the development and utilization of Laggera alata and the establishment of its quality standard.

Establishment of a Method for the Determination of Emodin in Wudajiangjun Liquor

[Objectives]To establish a method for the determination of emodin in Wudajiangjun liquor,a hospital preparation.[Methods]A high-performance liquid chromatography(HPLC)method for the determination of emodin in Rhizoma Polygontum Cuspidatum in hospital preparation Wudajiangjun liquor was established.Using HPLC method,octadecylsilane chemically bonded silica gel was used as filler for the chromatographic column[Inertsil-C 18 chromatographic column(5μm,4.6 mm×250 mm)].Methanol-0.1%phosphoric acid water(76∶24)was used as mobile phase.The flow rate was 1.0 mL/min,the column temperature was 30℃,the detection wavelength was 254 nm,and the injection volume was 10μL.[Results]The content of emodin in Wudajiangjun liquor was determined by reversed-phase high performance liquid chromatography(RP-HPLC).When the injection volume of emodin was in the range of 5.45-54.5μg/mL,there was a good linear relationship between the injection volume and the peak area.The regression equation is Y=42.952-15.068(r=0.9998),the average recovery rate is 98.23%,and RSD=1.45%.[Conclusions]A method for the determination of emodin in Wudajiangjun liquor by HPLC was established.This method can be used as a quality control method for Wudajiangjun liquor with high accuracy and good repeatability,which lays a foundation for the quality control of the medicinal liquor.
