    1. A simple method is presented for determining double bond index of pure unsaturated hydrocarbons, petroleum fractions and other hydrocarbon mixtures based on a correlation of observed refractive index, calculated refrac-tive index, molecular weight and the number of double bonds per molecule. The data neccessary are: (a) mid-boiling point, (b) refractive index at 20℃ for sodium D line, (c) density at 20℃ and (d) weight percent hydrogen of the

    依据在20℃钠D线折光率实测值,在20℃钠D线折光率计算值,分子量及每一分子内所含双键数间之相互关系,推衍得一简易方法,用以测定纯不饱和烃及石油分馏油份之双键率(Double Bond Index).所需由实验测得之数据为试料之(甲)在20℃钠D线折光率,(乙)在20℃时之密度,(丙)中间沸点(Mid-boiling point),及(丁)含氢重量百分数.用本法测得双键率值,与用尼蒲金(Lipkin),圣金(Sankin)及马丁(Martin)三氏法测得双键率值适相吻合.因此,用本法所测得之双键率,足资用以鉴定石油分馏油份内所含芳香族烃及烯(?)烃之主要型式.惟需指明者,即在依据本法测得之双键率,用以鉴定石油分馏油份内所含不饱和烃之主要型式时,必须测定由石油分馏油份内提出仅含不饱和烃浓缩物之双键率.

    1. The oil from fruits of Chinese drug,"Ya-tan-tze", Brucea javanica(Linn.) Merr., has been studied, and its physical and chemical constants determined. The composition of fatty acids and unsaponifiable matter were also individually identified. 2. The composition of fatty acids was fractionated by a specially modified method of fractional precipitation with silver nitrate solution, while the unsaturated fatty acids were fractionated with bromo-derivative method. The percentage contents of the various fatty acids present are as follows: (1) Saturated fatty acids: Arachidic acid......66.94% Unknown acid......30.09% Caproic acid......2.96% (2) Unsaturated fatty acids: Oleic acid......99.25% Linolenic acid......0.75% Clupanodonic acid......trace 3. From the unsaponifiable matter fraction, a higher homologue of hydrocarbon was isolated. It is a kind of colourless flake crystal, m.p. 61-63℃, its formula being proposed as C_(35)H_(72) by molecular weight(Rast method) determination. This hydrocarbon is thus preliminarily proved as an isomer of pentatriacontane, a new constituent in this genus of the plant, although the isolation of another hydrocarbon, hentriacontane, C_(31)He_(64), from the fruits of Brucea sumatrana Roxb. had been previously reported. Besides the hydrocarbon, a trace of phytosterol was also found in the unsaponifiable matter, its acetylated product, a kind of colourless thin flake crystal, m.p. 104-106℃, admixed with a trace of paraffin wax.

    此部分工作是作者於1942年在昆明前中央藥物研究所完成,近閱1950年中華醫學雜誌有于光元及李寶實两氏,又1955年中華耳鼻喉科雜誌有王世勳、陳守毅兩氏相继發表的关於鴉胆子固定油具有醫疗乳头瘤或及外耳道和喉乳頭狀瘤之臨床效能报告,为配合此方面研究與决定有效成分問题的發展,作者謹將此文發表。根據本研究,這植物果實固定油成分中含种類繁複的脂酸類和特異的高碳烃及(石享)類等化合物。這似與近年Grabtree及Patter等氏報導關於有機不飽和酸類抑制瘤腫作用有关,(Cancer Research,2:688,1942;4:688,1944:5:546,1945)頗足为探研鴉膽子油治瘤有效成分的参考。

    In this paper a modified method is recommended for the determination of rubber hydrocarbon present in kok-saghyz rubber by means of bromination.This method is rapid and accurate.A conversion factor of 0.298 is obtained for con- verting rubber bromide content to rubber hydrocarbon content for kok-saghyz rubber.The conversion factor agrees well with the theoretical value.

    本文报告了用重量溴化法测定青橡胶草生胶中橡胶烃的各种适宜条件,并求得了由溴化橡胶换算为橡胶烃的换算因数为0.298。三氯甲烷可用来防止溴化橡胶的结膜,同时并可防止溴与橡胶的置换反应。每10毫升橡胶液应加溴化溶液2毫升。溴化反应可在常温进行。三氯醋酸可使橡胶容易溶解,对分析结果无显著影响,用或不用均可。溴化法无论在分析时间上和精确度上,均较直接抽提法和间接测定法为优。
