  Processes of making extracts of Hoodia plant containing steroidal glycosides which have improved flavor, by virtue of reduced levels of discovered negative flavor compounds, comprising: a. dissolving initial Hoodia extracts in an oil, to obtain a solution of the extract; b. heating the solution, under vacuum, to a temperature in the range of from about 80 to about 140°C; c. removing negative flavor compounds by stripping the heated solution, under vacuum, with a gas stream, to obtain Hoodia extracts of improved flavor.

  制造含有甾体苷的 Hoodia 植物提取物的工艺，由于减少了已发现的负面风味化合物的含量，这些提取物的风味得到了改善，其工艺包括 a. 将最初的 Hoodia 提取物溶解在油中，得到提取物溶液； b. 在真空条件下，将溶液加热到约 80 至约 140°C 的温度范围内； c. 在真空下，用气流剥离加热溶液，去除负风味化合物，以获得风味更好的 Hoodia 提取物。

  ruthenium complex allows control of regioselectivity in the ruthenium-catalyzed isomerization of propargyl alcohols through the choice of additive. Thereby, both products of the Meyer–Schuster rearrangement and redox isomerization products are selectively accessible. In the presence of hydroxylamine-O-sulfonic acid, unsaturated nitriles are formed instead. The ruthenium catalyst is readily available and

  二氨基环戊二烯酮钌络合物可以通过选择添加剂来控制钌催化的炔丙醇异构化的区域选择性。因此，Meyer-Schuster 重排产物和氧化还原异构化产物都可以选择性地获得。在羟胺-O-磺酸存在下，反而形成不饱和腈。钌催化剂易于获得，并且对水分、空气和酸性条件稳定。
