The project implemented a systemic investigation to the pupa period of wild silkworm comparatively, which from Shanxi, Jiangsu, Sichuan, Chongqing, Guizhou provinces and so on. According to the investigation, the pupa dormant characteristic of Shaanxi wild silkworm was found, and the individual, which pupa period was more than two months was selected. Through the hybrid genetic analysis we found that the characteristics for a long period of pupa was controlled by polygene and genetic recessively and strongly influenced by environmental conditions at the same time. To compare the performance of pupa period of the pupa dormant wild mulberry silkworm, we designed different ecological conditions. The result indicating that the temperature is the main factor in the ecological impact, but the pupa period was extended at the same temperature conditions, indicating that the additive effects of the environmental factors.

In this paper, firstly using natural fatty acids including lauric acid, myristic acid, palmitic acid etc. and disproportionated rosin as starting materials, the acyl reaction of starting materials with SOCl_2 respectively, and then using Schotten-Baumann condensation: on the reaction conditions of alkalescence, condensation of acylchloride with amino acid (sarcosine, glycine, alanine etc.), and then acidification, saltation. A series of anionic surfactants of N-acyl amino: sodium N-fatty acyl sarcosinate (SFS-12, SFS-14, SFS-16); sodiun N-fatty acyl glycinate(SFG-12, SFG-14, SFG-16); sodium N-fatty acyl alaninate(SFA-12, SFA-14, SFA-16)and sodium N-disproportionated rosinoyl aminatewere prepared. During the preparation of N-acylamino acid, the reaction conditions of acylchloride with amino acid condensation were identified by optimizing the synthetic conditions of N-lauroyl sarcosine: mol ratio of amino acid to acylchloride 2:1, reaction taken place in a solvent composed by acetone/water 2:1, acylchloride and 20% NaOH were slowly added to the reaction mixture at the same time while maintaining the pH at 9~10, after completion of adding maintaining reacting for 2.5h at 25℃.

The studies was proceeded on the the supercritical CO2 extraction technique of rotenone from Tephrosia vogelii. The extraction influences of technology conditions were systematically groped, The research results were listed as follows:1 The analysis method applied in this paper has been proved to be suitable to technology research of the studies on the SC-CO: extraction technique of rotenone from Tephrosia vogelii. 3 indexes, extraction ratio of rotenone. extraction ratio of total compounds and rotenone content percent in total compounds weight, were carried out with HPLC quantitatively determination combined with the sample weight loss after extraction. With these 3 indexes. The extraction influences of technology conditions were evaluated by synthesis. Then the best technology conditions were ascertained for different extraction aims.2 The pretreatment of rough material should be needed before extraction. Comminuting the material to 0.28mm size is most fit to SC-CO: extraction.3 Firstly static extracting 20 min then turn to dynamic doing is the better extraction mode than other ones.4 The orthogonal experiment was conduct with 3 factors and 5 levers.
