【摘要】 <正> Eagleson曾试以24种动植物油与除虫菊合用,试验其对家蝇所发生的毒效,结果仅芝麻油对除虫菊有极显著的增效作用。Haller 等以分子蒸馏法自芝麻油中分离得对除虫菊素增效最强的物质,并证明为芝麻素。作为商品除虫菊内的增效剂的芝麻素浓缩剂,系自芝麻油提出。据 Martin 等报道,各种芝麻油含有芝麻素由0.25%以至1.75%;Suarez 等报道芝麻油含芝麻素0.77%至1.06%,商品芝麻素浓缩剂含有芝麻素5.13—19.23%,脱去芝麻素的芝麻油尚含有芝麻素0.14%。更多还原

【Abstract】 A reagent prepared from 2 volumes of 78-79% H₂SO₄ solution and 1volume of 26-27% H₂O₂ solution is capable of giving with sesamin a greencoloration finally turning yellow.The yellow color may be utilized for thequantitative determination of sesamin,and satisfactory results can be obtained.This method has been employed to determine the sesamin content in oils of 16varieties of Chinese sesamin seeds,which ranges from 0.92% up to 1.80%.Oilscontaining high quantities of sesamin should have promising potential uses asasynergist in combination with pyrethrin oil sprays.更多还原
