Abstract:

The new triterpene saponin 3-O-β-ᴅ-glucopyranoside, 28-β-ᴅ-glucopyranosyl-(1→2)-β-d-glucopyranosiduronic acid oleanolate was isolated from the roots of Chenopodium ficifolium. The known compounds stigmasterol-3-O-glucoside and 3-O-β-ᴅ-glucopyranosiduronic acid, 28-β-ᴅ-glucopyranosyl oleanolate were also isolated. The latter compound, oleanolic acid, β-sitosterol and its glucoside were isolated from the aerial parts. The identity of these compounds was verified through different chemical and physico-chemical evidences including different 1D and 2D NMR experiments.

Abstract:

Inseparable Ursolic acid and its isomeric oleanolic acid are the major compounds in Fagraea fragrans fruits. The white solid crystals , 3.1 % of these triterpenic acids are easyly isolated from alcoholic extracts of these dried fruits. They are well known in both cosmeticeutical and medicinal industries. Therefore the objective of this work is to derivative those to be the inseparable ethyl ursolate 3-ethyl ether [its isomeric ethyl oleanolate 3-ethyl ether], and to evaluate their anticancer activity against P-388 murine leukemia cells. The results are 71% of the derivatives have been successf

Abstract:

(1) Background: The aim of the presented work was to obtain a set of oleanolic acid derivatives with a high level of anticancer activity and a low level of toxicity by applying an economic method. Three types of oleanolic acid derivatives were obtained: (i) derivatives of methyl oleanonate oxime, (ii) derivatives of methyl oleanonate oxime with an additional 11-oxo function, and (iii) derivatives of morpholide of oleanonic acid oxime. (2) Methods: The above oximes were acylated with aliphatic or aromatic carboxylic acid. The newly obtained compounds were subjected to ADMETox analysis and were
