Zusammenfassung:FIELD: chemical technology. ^ SUBSTANCE: invention relates to methods for preparing oleanolic acid used as a standard sample (comparison samples) in carrying out standardization of medicinal vegetable raw and phytopreparations comprising triterpene saponins - derivatives of oleanolic acid. For preparing oleanolic acid method involves sum of saponins extracted by alkaline extraction from sugar or table beet root crops followed by reprecipitation in acid medium and extraction of precipitate with ethanol, chloroform. Method provides preparing oleanolic acid of high purity degree from inexpensive and available raw. ^ EFFECT: improved preparing method. ^ 2 cl, 3 ex
