过山枫Celastrus aculeatus为卫茅科植物。药用其根,治疗类风湿性关节炎总有效率为50%,其中显效达26.3%。过山枫的化学成分未见报导,我们提取分离得三种结晶,经鉴定为卫茅醇和β-谷甾醇,另一结晶待鉴定。一、提取分离:过山枫粉25公斤,用95%乙醇回流二次,每次四小时,热滤,回收乙醇,得醇浸膏,用沸水提取,浓缩,放置,析出结晶Ⅰ,得率为0.8%。醇浸膏水不溶部分,用乙醚提取,乙醚提取物用中性氧化铝柱层分离,以乙醚洗脱,经薄层鉴定,相同斑点流份合并,分别得到结晶Ⅱ和结晶Ⅲ。二、鉴定:结晶Ⅰ以水重结晶,得白色透明棱柱体结品,熔点189～190℃,易溶
Over the Mountain Maple Celastrus aculeatus for the Wedelia family. Medicinal roots, the total effective rate of treatment of rheumatoid arthritis is 50%, of which significant effect of 26.3%. There are no reports on the chemical composition of T. bungeana. We extracted three crystals and identified it as Weiduo alcohol and β-sitosterol. The other crystal was identified. First, extraction and separation: 25 kg of mountain maple powder, refluxed with 95% ethanol twice, four hours at a time, heat filtration, recovery of ethanol, alcohol extraction, extraction with boiling water, concentration, deposition, precipitation of crystallization I, yield 0.8%. The water-insoluble portion of the alcoholic extract was extracted with ether. The ether extract was separated on a column of neutral alumina and eluted with ether. The thin layer was identified and the same spot fractions were combined to give crystal II and crystal III, respectively. Second, identification: crystal I recrystallized in water, white transparent prismatic product, melting point 189 ~ 190 °C, soluble
