Oleanolic acid as a potential drug molecule: A review

open access: yes, 2023
Objective: Oleanolic acid is traditionally used medicinal remedies in India. Oleanolic acid or oleanic acid is a naturally occurring pentacyclic triterpenoid related to betulinic acid. It is widely distributed in food and plants where it exists as a free

Oleanolic acid enhances insulin secretion in pancreatic β-cells [PDF]

open access: yes, 2008
We investigated the effect of oleanolic acid, a plant-derived triterpenoid, on insulin secretion and content in pancreatic β-cells and rat islets. Oleanolic acid significantly enhanced insulin secretion at basal and stimulatory glucose concentrations in ...

Enhancement of Platelet Aggregation by Ursolic Acid and Oleanolic Acid [PDF]

open access: yesBiomolecules & Therapeutics, 2014
The pentacyclic triterpenoid ursolic acid (UA) and its isomer oleanolic acid (OA) are ubiquitous in food and plant medicine, and thus are easily exposed to the population through natural contact or intentional use. Although they have diverse health benefits, reported cardiovascular protective activity is contentious. In this study, the effect of UA and

Three Oleanolic Acid Glycosides from the Seeds of

open access: yesNatural Product Communications, 2007
From the seeds of Achyranthes aspera three triterpenoid glycosides were isolated and their structures elucidated on the basis of NMR spectroscopic, mass spectrometric and degradative studies as α-L-rhamnopyranosyl-(1→4)-(β-D-glucopyranosyluronic acid)-(1→
