Herbal textual research on triditional Chinese medicine "Baihe"( Lilii Bulbus) / 中国中药杂志

To clarify the species and preparation of " Baihe"( Lilii Bulbus),a traditional Chinese medicine,we investigated the relative ancient Chinese literature on this medicine. The study concluded that Lilium brownii var. viridulum is the authentic lily for medical use. In the Ben Cao Yan Yi and some medical books in the Ming and Qing Dynasties,L. lancifolium( Juandan) was also mistakenly used as genuine lily,but most doctors believe that this variety should not be used for medicinal purposes; L. pumilum( Shandan)began to be used as a medicine from Ri Hua Zi Ben Cao,but mainly for surgery,the effect is also different from L. brownii var. viridulum. We suggested Shandan be used as the species for another medicine as " Hong Bai He( red lily) " due to its red flower. All above three species recorded in the Chinese Pharmacopoeia are not corresponded to the condition of ancient doctors' uses. Therefore,as for developing of traditional classical formula,L. brownii var. viridulum should be chosen and used as Baihe. The birth places for Baihe include Gansu,Hubei,Anhui and Shandong province. The drug preparations of Baihe include crude medicine,roasting and steaming,which preparation should be chosen depends on the formula which contains Baihe.

Herbal textual research on Chinese medicine "Manjingzi"(Viticis Fructus) / 中国中药杂志

To clarify the change and development of original plants of " Manjingzi"( Viticis Fructus),a traditional Chinese medicine,we investigated Vitex species on the ancient Chinese herbal texts. The study concluded that the Vitex trifolia and V. trifolia var.simplicifolia included in the Chinese Pharmacopoeia( 2015 edition) are only two sources of ancient medicinal Viticis Fructus. There are many sources of vines used in ancient times,which are not fixed and unified. The early use of Viticis Fructus is likely to be the V. quinate var. quinata,V. negundo var. cannabifolia and V. negundo var. negundo. From the Tang Dynasty,the use of V. trifolia var. simplicifolia has been appeared. Until Li Shizhen of the Ming Dynasty,the V. trifolia has been used as a source of medicine for the Viticis Fructus,but even so,the source of medicinal plants of Viticis Fructus has not been unified. We suggested V. trifolia var. simplicifolia be used as mainly species for " Manjingzi" due to its widely used in ancient China.

Technology of combining field processing and crude drug processing of Anemarrhenae Rhizoma / 中草药

Objective To optimize the method for integration of field processing and crude drug preparation of Anemarrhenae Rhizoma (AR) and to provide scientific evidence for the procedure of AR. Methods Four main factors including drying temperature of the fresh herbal medicine, the water content of the medicine, thickness of the products, and the drying temperature of decoction pieces were studied by using single factor experiment and orthogonal test. The content of timosaponin B-Ⅱ and mangiferin and the appearance of the products were selected as evaluation indexes to optimize the integral processing of AR by using comprehensive evaluating method. The changing of the body temperature of yeast-induced rat model was used to compare the antipyretic activity between the two processing technologies (the integration technology and traditional technology). The content of the blood glucose, insulin, and glycosylated serum proteins (GSP) in the blood of the STZ-induced diabetic rat model were selected as the evaluation indexes to compare the hypoglycemic activity between the two processing technologies. Results AR was dried at 50 ℃ for 11 h (water content of medicinal materials was 45%—50%), and then the flosses were knocked off in the drum for 30 min. The results showed that 40—50 ℃ was the best drying temperature, 45%—50% was the best water content, and then unhairing process were conducted for AR for 30 min. The thickness of the slice was 4 mm and the best drying temperature was 50 ℃. There were no significant differences in chemical composition and hypoglycemic activity between the integration technology and traditional technology, while the antipyretic effect of the integrated processing was better than that of the traditional technology. Conclusion The technology of integration of field processing and crude drug processing is feasible and it can be used in industrial production.

Study on processing technology optimization of wine radix scutellariae by orthogonal design / 重庆医学

Objective To screen the optimized processing technology of wine radix Scutellariae .Methods With the the com‐prehensive score of the yield rates of baicalin ,wogonoside and baicalein as the index ,the orthogonal design was used to investigate the mass fractions of yellow wine quantity ,stir‐frying temperature and frying time of wine radix Scutellariae .Results The optimum yellow wine mass fraction was 10% ,the stir‐frying temperature was 120℃ ,the frying time was 6 min ,and this processing technolo‐gy was stable and feasible .Conclusion The orthogonal design can be used for the optimization of processing technology of wine ra‐dix Scutellariae .

Some Key Problems during Quality Standard Research of Pieces of Chinese Crude Drugs / 世界科学技术-中医药现代化

Quality standard research of pieces of Chinese crude drugs is the important content of research of Chinese medicine processing, and it is also the key point of the whole standardization system of Chinese medicine. Although we have set up a preliminary quality standard system of pieces of Chinese crude drugs, it still under a low level. During the research of quality standard of pieces of Chinese crude drugs, we still face some problems, such as how to set up a more comprehensive, scientific, and reasonable quality standard. In this paper, we proposed some advices that we should pay more attention to traditional processing theories, processing mechanisms and effective substances during research of quality standard research of pieces of Chinese crude drugs.

Optimization Research on Technology of Extracting Evodia rutaecarpa Juice——Crude Drug Processing Adjuvant of Yuhuanglian / 中国中医药信息杂志

Objective To discuss the best extracting technology of Evodia rutaecarpa juice——crude drug processing adjuvant of Yuhuanglian with water.Methods The content of 9 samples extracted according to orthogonal tests were mensurated by UV-spectrophotometry,and the extract methods were estimated with the content of total alkaloid in Evodia rutaecarpa as index.Results The technology of A3B2C1 that was marinated 60 minutes,added the water with 12,9.6 folds,extracted for 40 minutes,and extracted 2 times,which obtained the highest content of total alkaloid.Conclusion This test offered a pressing,feasible and best extracting technology of preparation of crude drug processing adjuvant of Yuhuanglian——Evodia rutaecarpa juice.
