Therapeutic Potential of Ursonic Acid: Comparison with Ursolic Acid [PDF]
Plants have been used as drugs to treat human disease for centuries. Ursonic acid (UNA) is a naturally occurring pentacyclic triterpenoid extracted from certain medicinal herbs such as Ziziphus jujuba. Since the pharmacological effects and associated mechanisms of UNA are not well-known, in this work, we attempt to introduce the therapeutic potential ...

Determination of ursolic acid and ursolic acid lactone in the leaves of Eucalyptus tereticornis by HPLC [PDF]
A simple isocratic HPLC method has been developed for the simultaneous quantification of two bioactive triterpenes, ursolic acid and ursolic acid lactone in E. tereticornis leaves. Samples were analyzed on RP-18 (4.6 × 250 mm, 5 µm) column with methanol and water acidified to pH 3.5 with TFA (88:12) at 210 nm.

Antiangiogenic Activity of Ursolic Acid
Angiogenesis, the formation of new capillaries from preexisting vessels, is essential for tumor progression. Ursolic acid inhibited the tumor-associated capillary formation in C57BL/6 mice induced by highly metastatic B16F-10 melanoma cells.

TRITERPENOIDS AND FLAVONOIDAL GLYCOSIDE FROM FRUITS OF SORBUS AUCUPARIA (DC) CULTIVATED IN EGYPT [PDF]
From the chloroform soluble fraction of ethanolic extract of the dried fruits of Sorbus aucuparia (DC)four triterpenes were isolated and identified as a-amyrin, ursolic acid, methyl 2a-hydroxy ursolate, 2a-hydroxy ursolic acid in addition to b-sitosterol.
