1Skin Toxicity of Wufang Babu Ointment to Zebrafish显示文摘[Objectives]Using wild-type AB strain of zebrafish as experimental animal,this study investigated the damaging effect of Wufang Babu Ointment on skin cells,in order to evaluate the skin toxicity of Wufang Babu Ointment.[Methods]Wild-type AB strain of zebrafish with an age of 2 d were taken and fed in different concentrations of Wufang Babu Ointment solution for 24 h.The number of deaths in each group of zebrafish was recorded,and the mortality rate was calculated.Using Origin 8.0 software,the maximum non lethal concentration(MNLC)was simulated.Zebrafish raised in different concentrations of Wufang Babu Ointment solution for 24 h were placed under an anatomical microscope for taking photos,to analyze and calculate the incidence of skin damage in zebrafish.Based on the statistical analysis results of this indicator,the skin toxicity of Wufang Babu Ointment was evaluated.[Results]The MNLC of Wufang Babu Ointment on zebrafish was 671μg/mL;Wufang Babu Ointment can induce skin damage at the concentrations of 224μg/mL(1/3 MNLC)and 671μg/mL(MNLC).[Conclusions]Wufang Babu Ointment had certain skin toxicity to zebrafish.Xiaoxia LI Jiabao MA Jing FU Jinhua LIU Xiongbin GUI 2024Medicinal Plant2024,15,2:0
2Preparation Process and Thin Layer Chromatography Identification of Wufang Babu Poultice显示文摘[Objectives] To establish the process flow of preparation of Wufang Babu Poultice and the identification method of thin layer chromatography (TLC). [Methods] For the forming process of Wufang Babu Poultice, the preparation method of mixed pharmaceutical powder with suitable pharmaceutical excipients was adopted. Qualitative identification of medicinal materials in Wufang Babu Poultice (Strychni Semen, Rhei Radix Et Rhizoma, Dipsaci Radix, and Angelicae Sinensis Radix) was carried out by TLC. [Results] Mixed pharmaceutical powder mixed with glycerol, gelatin and other pharmaceutical excipients can be prepared for forming. The test solution chromatography of each medicinal material (Strychni Semen, Rhei Radix et Rhizoma, Dipsaci Radix, Angelicae Sinensis Radix) showed pigment spots of the same color at the same position as its corresponding control medicinal materials and reference chromatography, and the display was clear. [Conclusions] The preparation process is simple and feasible, and can be used as the forming process of Wufang Babu Poultice. The TLC determination method is simple to operate, has good specificity, and has no effect on negative results, and can be used for identification of Wufang Babu Poultice.Junjun LIU Luyao XIE Chuhui ZHOU Zhengteng YANG Xiongbin GUI 2023Medicinal Plant2023,14,4:0
