Analysis on formulation regularity and characteristics of acne-relieving Chinese medicinal health products and Chinese patent medicines / 中国中药杂志

This study summarized and analyzed the current acne-relieving Chinese medicinal health products and Chinese patent medicines,aiming at providing references for the formulation and development of acne-relieving health products. The information on acne-relieving health products published by the Department of Special Food Safety Supervision and Management,the State Administration for Market Regulation( SAMR) was retrieved,and the Chinese patent medicines on DRUGDATAEXPY were searched. Microsoft Excel and the Traditional Chinese Medicine Inheritance Support System V2. 5( TCMISS) were employed to statistically analyze the characteristics of formulations. Forty-three acne-relieving health products were obtained,including 40 ones containing Chinese herbal medicines. Six Chinese herbal medicines showed a usage frequency ≥8,with 61 times in use totally,including Salviae Miltiorrhizae Radix et Rhizoma( 13),Lonicerae Japonicae Flos( 12),Taraxaci Herba( 11),ALOE( 9),Carthami Flos( 8),and Rhei Radix et Rhizoma( 8). A total of 29 Chinese patent medicines with similar efficacy were collected in DRUGDATAEXPY. Nine Chinese herbal medicines showed a usage frequency ≥6,with 63 times in use,including Rhei Radix et Rhizoma( 10),Glycyrrhizae Radix et Rhizoma( 8),Scutellariae Radix( 8),Lonicerae Japonicae Flos( 7),Angelicae Sinensis Radix( 6),Paeoniae Radix Rubra( 6),Astragali Radix( 6),Paeoniae Radix Alba( 6),and Gardeniae Fructus( 6). Through unsupervised hierarchical entropy-based clustering of the above-mentioned Chinese medicinal health products and Chinese patent medicines,five and three new formulas were obtained,respectively. The selection of Chinese herbal medicines was consistent with the principles of traditional Chinese medicine( TCM) theories in relieving acne,i. e.,dispelling exterior wind,ventilating lungs,clearing heat,dissipating mass,promoting diuresis,relaxing bowels,removing toxin,activating blood,resolving stasis,eliminating phlegm,and regulating Qi. According to the " lung governing skin and body hair" and " interior-exterior relationship between lung and large intestine" in TCM theories,the idea that acne could be treated by relieving constipation was proposed,which provided new methods and references for the research and development of Chinese medicinal health products.

Simultaneous determination of isoquercetin and astragalin in Moringa oleifera leaves prescription-a prescription for treatment of constipation by HPLC / 国际中医中药杂志

Objective To establish an HPLC method for simultaneous determination of Isoquercitrin and astragalin in Moringa oleifera leaves prescription. Methods By using HPLC method with Cosmosil-C18 column (4.6 mm × 250 mm, 5 μm) and the column temperature was 40 degrees Celsius, the mobile phase contains a 0.1％phosphoric acid in water(A) and acetonitrile(B), the detection wavelength was set at 350nm by UV detector and the flow rate was 1.3 ml/min. Results The Isoquercitrin and astragalin was better separated in 30 minutes, and Isoquercitrin had a good linear correlation at the range of 0.24-4.73 μg, while astragalin was 0.11-2.19 μg, the average spiked recoveries of isoquercetin and astragalin were 99.09％ (RSD=0.60％) and 99.08％ (RSD=1.37％), respectively. Conclusions The proposed method is simple,accurate,and repeatable and can be used for quality control as well as a powerful tool to evaluate the processing of Moringa oleifera leaves. It can provide the reference basis and data support for the determination of content of Moringa oleifera health products.
