乌柏[Sapium Sebnferm Roxb]中的微量元素,至今很少报道。无论从品种鉴选出发,还是以皮油作代可可脂来考虑,研究其微量元素的组成与含量;微量元素与品种(类型)或地域的差异性;微量元素对皮油品质的影响等等,都具有其特殊意义。材料与方法样品:测试样品的选取,既顾及不同品种(类型),又兼顾乌柏生长地域。全籽以干样粉碎。皮油系用正已烷(或石油醚)提取,大部溶剂回收,残余溶剂低温挥发除尽。全部用1988年采收的样品供测试。
The trace elements in Sapium Sebnferm Roxb have not been reported until now. Whether from the species selection, or oil as a substitute for cocoa butter to consider the composition and content of trace elements; trace elements and varieties (types) or geographical differences; trace elements on the quality of the impact of oil and so on , Have their special meaning. Materials and Methods Sample: The selection of test samples, taking into account the different varieties (types), but also take into account the area of Ubisch growth. The whole seed is ground in a dry sample. Peeling oil is n-hexane (or petroleum ether) extraction, most of the solvent recovery, residual solvent evaporation at low temperature. All samples collected in 1988 for testing.
