  Insecticidal Activity of Extracts, Fractions, and Pure Molecules of Cissampelos pareira Linnaeus against Aphid, Aphis craccivora Koch

  摘要：

  Aphis craccivora Koch是一种多食性和主要的豆科作物害虫，通过减少产量造成显著损害。反复使用合成杀虫剂来控制蚜虫已经导致了抗药性的产生。因此，本研究旨在筛选来自Cissampelos pareira Linnaeus的根/茎提取物/分馏物和纯分子的杀虫活性，以识别潜在的领先物质。在根提取物/分馏物中，正己烷分馏物对A. craccivora的效果最好（LC50 = 1828.19 mg/L），其次是母体提取物（LC50 = 2211.54 mg/L）。在茎提取物/分馏物中，正己烷分馏物（LC50 = 1246.92 mg/L）比水和正丁醇分馏物更有效。基于GC和GC-MS分析，在根和茎的正己烷分馏物中识别出的不同化合物中，乙酸乙酯（已知具有杀虫活性）在两个分馏物中的浓度最高（24.94至52.95％）。在纯分子中，pareirarineformate对A. craccivora的效果最好（LC50 = 1491.93 mg/L），其次是cissamine（LC50 = 1556.31 mg/L）。C. pareira的母体提取物和分馏物具有很好的杀虫活性。进一步的田间生物效力研究有必要验证当前的发现以开发植物制剂。

• Optimizing Reaction Conditions for the Isomerization of Fatty Acids and Fatty Acid Methyl Esters to Their Branch Chain Products

  AbstractIn order to improve the oxidative stability and cold flow properties of oleic acid or methyl oleate, branch chain isomerization was conducted using a beta zeolite catalyst. Reaction conditions of temperature (200–300 °C), pressure (0.1–3.0 MPa), and co‐catalyst (0–2 wt%) were optimized based on branch chain conversion and the cloud point of the ester following the isomerization reaction of oleic acid or methyl oleate. Fourier transform infrared spectroscopy (FTIR) and Gas Chromatograph equipped with Mass Spectrometry (GC/MS) analyses were used to analyze and quantify the isomerization product samples, while the cloud point of each sample was tested. The lowest and therefore, best cloud point measured was −15.2 °C at conditions of 200 °C, 3 MPa, and 2% co‐catalyst using methyl oleate as a starting material. The highest branch chain conversion achieved was 50% under conditions of 300 °C, 1.5 MPa and 0% co‐catalyst using oleic acid as a starting material. The use of oleic acid and methyl oleate is based on whether it is optimal to carry out the skeletal isomerization before or after the esterification reaction. Performing the isomerization reaction on the ester was preferred over the fatty acid based on the trans isomerization and cloud point results. Reducing the unbranched trans isomers was desirable in obtaining a low cloud point.

  The subject invention provides methods for producing biofuel from microorganism metabolite by using sugarcane as feedstock. In a preferred embodiment, alga was cultivated by using sugarcane- originated carbon 5 source as feedstock, resulting algal oil accumulation in algal cells at high content. And biodiesel was produced from said algal oil by transesterification.
