- 中文摘要: 3'?基柑果?與3'甲基柑果?,3'乙基柑果?及3'丁基柑果?之製造反應步驟相同,用氯化甲苯與柑果普反應時,加碳酸鎂或碳酸鈣作促進劑,亦可增高3'?基柑果?形成速度或減低其他衍生物之產生,產率可達85%,3'茶基柑果普之精製與31丁基柑果普同,用碳酸鈉及二氧化硫分離法,效果欠佳,若改用硫代硫酸鈉(Na2S2O3)將粗製品處理後,再用丁醇結晶之,則可得純3'茶基柑果昔,熔點為122-1240C,但其顏色仍為黃色,3'?基柑果?在有機溶劑內之溶解情形與巳製得之3'經基柑果?同,唯其在水中之溶度不大,與1%三氯化鐵溶液混合呈現黑褐色,3'?基柑果?對熱之敏感度與3'丁基柑果普相似,在丁醇溶劑內,約1300C加熱若干小時,共大部分亦能變為3'-benzylhesperidin chalcone, 3'茶基柑果?經硫酸水解,分裂為3'?基柑果?素,(熔點為105-108oC)葡芍糖及鼠李醣,3'?基柑果?及3'?基柑果?素在紫外線光譜上吸光度最高點均位于波長288mu處“
- 英文摘要: 3'-Benzylhesperidin has been obtained by the same reaction processes as thoseemployed in producing 3'-methylhesperidin, 3'-ethylhesperidin and 3'-butylhesperidin.In the reaction of hesperidin with benzyl chloride in alkaline solution one can alsouse calcium carbonate or magnesium carbonate as catalyst to increase the productionrate of 3'-benzylhesperidin and to suppress or diminish the formation of other deri-vatives;the maximum yield is 85%. The purification process of 3'-benzylhesperidinis somewhat like that of 3'-butylhesperidin. It is not advisible to treat it withsodium carbonate and sulfur dioxide. If it is treated with sodium thiosulfate andrecrystallized with butanol, pure 3'-benzylhesperidin can be obtained, a yellow sub·stance whose m.p. is 122-1240C. The solubility of 3'-benzylhesperidin in organicsolvents is as that of 3'-alkylhesperidin prepared previously but, in water, it is onlyslightly soluble. It appears dark brown when mixed with 1% FeCl3. 3'-benzylhespe-ridin, as 3'-butylhesperidin, is very sensitive to heat. If heated for a certain timein butanol solution, it is partially transformed to 3'-benzylhesperidin chalcone.3'-benzylhesperidin can be hydrolysed by sulfuric acid solution and, as a result,3'-benzylhesperetin(m.p. 105-108oC),glucose and rhamnose are formed. In the ultra-violet absorption spectrum, 3'-benzy1hesperidin and 3'-benzy1hesperetin have a peakat wave length 288 m.u.
