 It provides new ideas for quality control and research of ultrafine granular powders of traditional Chinese medicine.Uniform design-comprehensive scoring method was used to investigate the effects of ethanol dosage, ethanol concentration and extraction time, based on the evaluation index from transfer rates of epimedin A, epimedin B, epimedin C, icariin and baohuoside Ⅰ, which are the main active components in Epimedii Folium. Furthermore, the optimum conditions for the ethanol extraction process were determined by multiple linear stepwise regression and empirical test. Then, the ethanol extract of Epimedii Folium prepared according to the optimized technological conditions was used to intervene the injury model of chondrocyte induced by interleukin-1 beta(IL-1β). Annexin V-FITC/PI staining flow cytometry was used to detect the apoptotic rate of chondrocyte and analyze the effect of ethanol extract of Epimedii Folium on chondrocyte injury model. The optimum conditions of ethanol extraction were as follows. Crude powder of Epimedii Folium was added with 18 times of 70% ethanol solution, and extracted for twice in the refluxing process, for 60 minutes each time. Under the conditions, the extraction rates of the above five active components were 94.21%, 94.76%, 93.85%, 96.17% and 96.85%, respectively. The optimized ethanol extraction process of Epimedii Folium was reasonable, feasible and reproducible. This ethanol extract could significantly reduce the early apoptotic rate, late apoptotic and necrotic rate, total apoptotic rate(P less then 0.05 or P less then 0.01) of chondrocyte injury model induced by IL-1β, suggesting that the ethanol extract of Epimedii Folium can inhibit the apoptosis of chondrocytes induced by IL-1β to a certain extent, which lays a foundation for further study on its prevention and treatment of osteoarthritis.There were significant differences in phenolic acid content between fresh and dried Salvia miltiorrhiza before and after drying. That is to say, the content of phenolic acid in S. miltiorrhiza significantly increased with the increase of dehydration during the drying process.In order to investigate the differences and transformation of free and bound phenolic acids before and after the drying process of S.miltiorrhiza, we studied hydrolysis method, hydrolysates and hydrolysis regularity of phenolic acids in S.miltiorrhiza. UPLC method was used to determine four main hydrolysates of bound phenolic acids, namely danshensu, caffeic acid dimer(SMND-309), caffeic acid, przewalskinic acid A(prolithosperic acid), and three main free phenolic acids in S.miltiorrhiza, namely rosmarinic acid, lithospermic acid, salvianolic acid B. The results of the acid-base hydrolysis experiment of salvianolic acid showed that the alkaline hydrolysis effect was significantly better than acid hydrolysis. The optimal alkaline hydrolysis condition was hydrolysis at 70 ℃ for 4 h with 2 mol·L~(-1) NaOH solution containing 1% ascorbic acid(Vit C). The hydrolysates of free phenolic acids were the same with the hydrolysates of bound phenolic acids. Fresh S.miltiorrhiza contains a low level of free phenolic acids and a high level of bound phenolic acids, which were exactly opposite to dried S.miltiorrhiza. It was suggested that a large amount of bound phenolic acids was accumulated during the growth of S.miltiorrhiza. These bound phenolic acids were coupled with polysaccharides on the cytoderm through ester bonds to form insoluble phenolic acids, which was not easy to be detected by conventional methods. However, during drying and dehydration processes, the bound phenolic acids were converted to a large amount of free phenolic acids under the action of the relevant enzyme.Some Chinese herbal medicine needs to be processed before it can be used as medicine, especially toxic Chinese medicine. Highly toxic Aconti Kusnezoffii Radix(Caowu in Chinese) is widely used in traditional Chinese medicine and Mongolian medicine. In traditional Chinese medicine, Caowu is usually processed by boiling with water(CW) until no white part inside and being tasted without tongue-numbing. In Mongolian medicine, it is usually soaked in Chebulae Fructus(Hezi in Chinese) decoction for several days(CH). Both methods could reduce toxicity according to reports. The biggest difference between CW and CH is that CW needs to be heated for 4-6 h, while CH needs Hezi as processing adjuvants. To explore the toxicity reduction mechanism of CW and CH, we studied the contents of various compounds in Caowu processed by two methods by UPLC-Orbitrap-MS. The results indicated that CW had 14 new ingredients, such as 14-O-anisoylneoline and dehydro-mesaconitine, while N-demethyl-mesaconitine and aconitine disappeared. At the same time, it could significantly decrease the content of diester diterpenoid alkaloids and increase the contents of monoester diterpenoid alkaloids and amine-diterpenoid alkaloids. CH had 9 new ingredients from Hezi, like gallic acid, chebulic acid and shikimic acid.  https://www.selleckchem.com/products/decursin.html  Neither the kinds nor the contents of compositions from Caowu in CH changed little. This suggested that the processing mechanism of CW reduced highly toxic components(diester diterpenoid alkaloids) and increased the content of lowly toxic components(monoester diterpenoid alkaloids and amine-diterpenoid alkaloids). Attenuated principle of CH may be related to the components of Hezi. In this experiment, the conclusion shows that the chemical constituents of CW and CH are essentially different, and the two methods have different toxicity reduction principles.To prepare the herpetolide A nanosuspension lyophilized powder(HPA-NS-LP), in order to investigate its anti-hepatitis B virus(HBV) activity and the dissolution in vitro. Herpetolide A nanosuspension(HPA-NS) was prepared by ultrasonic precipitation method. The formulation and process of HPA-NS were optimized by the single factor experiment. Lyophilized powder(HPA-NS-LP) was prepared by freeze-drying method.  https://www.selleckchem.com/products/decursin.html  Scanning electron microscopy was used to observe morphology of HPA-NS-LP. Paddle method was used to determinate the dissolution of HPT-NS-LP in vitro. The anti-HBV activity of herpetolide A coarse suspension lyophilized powder(HPA-CS-LP) and HPA-NS-LP was evaluated by HepG2.2.15 cell model. The mean particle size of optimized HPA-NS was(173.46±4.36) nm, with a polydispersity index of 0.110±0.012. After redispersion, the mean particle size and the polydispersity index of HPA-NS-LP increased, with changes within a rational range. Scanning electron microscopy showed that HPA-NS-LP was spherical in shape. Cumulative dissolution rate of HPA-NS-LP was more than 90% in 2 hours, which was higher than that of HPA-CS-LP.
