刺玫果为蔷薇科植物野蔷薇(Rosadavurica Pall.)的干燥成熟果实,产于全国许多省区,其中以东北地区资源最为丰富、产量最大。近年,对刺玫果的研究表明,刺玫果具有多方面的生物活性,是一种大有开发利用价值的保健抗衰老天然药物。已知刺玫果含有大量的多种维生素、氨基酸、微量元素及脂肪油为了深入阐明刺玫果的化学成分,作者对刺玫果中的三萜类化合物进行了研究。将刺玫果的甲醇提取物悬浮于水中,以乙醚萃取,得到乙醚提取物。乙醚提取
Rosa roxburghii is a dry mature fruit of Rosadavurica Pall. It is produced in many provinces and regions in the country, among which the northeastern region has the most abundant resources and the largest yield. In recent years, studies on prickly pear fruit have shown that prickly pear has many biological activities and is a natural health-care anti-aging drug with great value for development and utilization. It is known that spiny rose fruit contains a large amount of vitamins, amino acids, trace elements, and fatty oils. In order to further clarify the chemical constituents of Rosa roxburghii, the authors studied the triterpenoids in the fruit of Rosa roxburghii. The methanol extract of prickly pear was suspended in water and extracted with ether to give an ether extract. Ether extraction
