Effect of Crude Drug Extracts on Trypacidin Production in Aspergillus fumigatus

We examined the production of fungal metabolites as biological responses to 120 crude drugs by culturing the filamentous fungus Aspergillus fumigatus CBS101355 with crude drugs and analyzing the culture extracts by HPLC. Nine crude drug extracts [Kyokatsu (Notopterygium), Kyonin (apricot kernel), Kujin (Sophora root), Goboshi (Burdock fruit), Goma (sesame), Shokyo (ginger), Shin’i (magnolia flower), Togashi (Benincasa seed), and Bukuryo (Poria sclerotium)] induced the production of trypacidin, which was not produced by culturing in potato dextrose broth without crude drugs.

Optimization and pharmacodynamic evaluation of stir-frying with bran for Tangshen processing

Background:Traditional Chinese medicine requires special processing before it can be effectively used for clinical treatment of diseases.In particular,Tangshen stir-fried with wheat bran smoke has been found to enhance the function of the stomach and spleen.However,there is limited research on the technology and pharmacodynamic effects of Tangshen fried with bran.Therefore,the objective of this article is to optimize the method of stir-frying with bran for Tangshen processing and to compare the anti-fatigue and hypoxia-resistance effects of Tangshen before and after bran-frying.Methods:The response surface methodology was utilized to optimize the frying temperature,frying time,and the bran-to-Tangshen ratio,using lobetyolin as the indicator.The swimming time of mice and the levels of blood urea nitrogen,lactate dehydrogenase,and blood glucose in fatigued mice were compared before and after Tangshen was fried with bran.Additionally,the hypoxic resistance ability of Tangshen before and after bran-frying was determined through normobaric hypoxia test and sodium nitrite poisoning test.Results:The optimal bran-frying conditions for Tangshen processing were determined as:frying temperature of 167°C,frying time of 2.67 min,and the bran-to-Tangshen ratio of 50:100.Pharmacodynamic analysis results indicated that Tangshen significantly increased the GLU content(P<0.01)and significantly reduced the LDH content(P<0.01)both before and after bran-frying.While both traditional and new bran-frying methods significantly increased the content of muscle glycogen(P<0.05),the optimized method in this study also significantly elevated the content of liver glycogen(P<0.05).The traditional method significantly prolonged the survival time of mice from sodium nitrite poisoning(P<0.05).Conclusion:The response surface model proved to be highly effective in optimizing the stir-frying process with bran for Tangshen processing.The results of this study indicate that Tangshen possesses anti-fatigue and hypoxia-resistance effects both before and after bran-frying,with bran-fried Tangshen exhibiting significantly stronger effects.

Research Progress of the Wild Medicinal Plant,Pinellia ternata

Based on literature reviews and analysis of research reports on Pinellia ternata found locally and abroad in recent years,this article summarizes and arranges them.The research on Pinellia ternata mainly focuses on its cultivation,tissue culture,and so on.There are only a few research on its active components and its regulation mechanism.The wild resources of Pinellia ternata are gradually decreasing,hence it is urgent to take effective measures to protect these wild resources as well as to establish germplasm resources bank and nursery.In order to meet the needs of the domestic market,it is necessary to investigate the distribution of wild Pinellia ternata resources,explore the best growing environment and conditions,artificially cultivate Pinellia ternata,as well as implement resource industrialization,sustainable development,and utilization.

Study on the Quality Standard of Heracleum moellendorffii Hance.

[Objectives]This study was conducted to investigate the quality standard of Heracleum moellendorffii Hance.,so as to provide data support for the 2003 version of Quality Standards for Chinese Medicinal Materials and Ethnic Medicinal Materials in Guizhou Province.[Methods]H.moellendorffii was subjected to character identification and microscopic identification.Referring to Chinese Pharmacopoeia,TCL thin-layer identification and extract determination were carried out on 10 batches of H.moellendorffii from 6 habitats in Guizhou.[Results]The characters and microscopic characteristics of H.moellendorffii were described in detail.The TLC thin-layer identification spots were clear,with strong specificity.The limit of the medicinal material extract was determined to be not less than 22.0%.[Conclusions]This study can provide data support for the quality evaluation and standard improvement of the medicinal material H.moellendorffii.
