Herbalogical study of Colla Corii Asini(Ejiao) / 中国中药杂志

Colla Corii Asini(Ejiao)is an important Chinese medicine used in China for thousands of years, and is well known for its famous tonic properties. The herbalogical study was detailed carried out based on the naming, habitat, harvesting, processing, medicinal properties and clinical efficacy. The results showed that the name of Ejiao could be traced back to Shennong's Materia Medica, and various names of Lvpi Jiao, Penfu Jiao and Fuzhi Jiao were recorded in other ancient books. In the many intervening centuries, the main materials of Ejiao had been replaced from cow leather before Tang Dynasty to donkey skin in the middle to late Tang Dynasty. This phenomenon could be probably caused by complicated social factors of various periods and different efficacy of Ejiao made by all kinds of raw materials. Ejiao was merely processed with the simple methods before Tang Dynasty, which subsequently improved avariety of methods to enhance the supplementation action. Most importantly, Ejiao has a wide clinic application along with the development of processing theories and methods, which can be found in various Classics, especially in imperial medical case record in Qing Dynasty.

Effect of selected fungi on the reduction of gossypol levels and nutritional value during solid substrate fermentation of cottonseed meal / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

The objective of this work was to investigate the effect of six individual strains of fungi on the reduction of gossypol levels and nutritional value during solid substrate fermentation of cottonseed meal (CSM). Six groups of disinfected CSM substrate were incubated for 48 h after inoculation with either of the fungi C. capsuligena ZD-1, C. tropicalis ZD-3, S. cerevisae ZD-5, A. terricola ZD-6, A. oryzae ZD-7, or A. niger ZD-8. One not inoculated group (substrate) was used as a control. Levels of initial and final free gossypol (FG), crude protein (CP), amino acids (AA) and in vitro digestibility were assayed. The experiment was done in triplicate. The experimental results indicated that microbial fermentation could greatly decrease (P<0.05) FG levels in CSM. The detoxification efficiency differed between the species of microorganisms applied. From the perspective of reducing CSM potential toxicity, C. tropicalis ZD-3 was most successful followed by S. cerevisae ZD-5 and A. niger ZD8. They could reduce FG levels of CSM to 29.8, 63.07 and 81.50 mg/kg based on DM (dry matter), respectively, and their detoxification rate were 94.57%, 88.51% and 85.16%, respectively. If crude protein, amino acids content and their in vitro digestibility were also taken into account, A. niger ZD-8 may be the best choice. The CP content of CSM substrate fermented by C. tropicalis ZD-3 and A. niger ZD-8 were improved by 10.76% and 22.24%; the TAA (total amino acids) contents were increased by 7.06% and 11.46%, and the EAA (essential amino acids) were raised by 7.77% and 12.64%, respectively. Especially, the levels of methionine, lysine and threonine were improved greatly (P<0.05). The in vitro CP digestibility of CSM fermented by C. tropicalis ZD-3 and A. niger ZD-8 was improved by 13.42% and 18.22%, the TAA were increased by 17.75% and 22.88%, and the EAA by 16.61% and 21.01%, respectively. In addition, the in vitro digestibility of methionine, lysine and threonine was also improved greatly (P<0.05).
