Ursolic acid as a trypanocidal constituent in rosemary.
The MeOH extract of the leaves of rosemary (Rosmarinus officinalis L.) completely inhibited the motility of cultured epimastigotes of Trypanosoma cruzi at the concentration of 2 mg/ml after 2 h of incubation. Activity-guided fractionation of the MeOH extract has resulted in the isolation of three triterpene acids, betulinic, oleanolic and ursolic acids. Ursolic acid stopped the movement of all ...
متن کاملUrsolic acid: a versatile triterpenoid compound in regulating the aging
We and other studies have elucidated single molecules that can attenuate aging and extend longevity. Indeed, these molecules could prevent age-associated diseases simultaneously and probably extending healthy-life spans. In this review, we discuss recent advances, controversies, opportunities and challenges surrounding ursolic acid (UA) in relationship with aging. In this regard, UA also known ...
متن کاملCx-aminoadipic Acid as a Constituent of a Corn Protein*
In a study of transaminase systems Braunstein (1) learned that cr-aminoadipic acid takes part in transamination. Both pigeon breast muscle mince and a purified glutamic transaminase extracted from it were active in transferring an amino group from alanine to a-ketoadipic acid. A plant aspartic transaminase was inactive with the same substrate. Experiments by Borsook and Dubnoff (2) on the synth...
متن کاملDetermination of Ursolic Acid and Ursolic Acid Lactone in the Leaves of Eucalyptus tereticornis by HPLC
Um método simples, isocrático, de HPLC foi desenvolvido para quantificação simultânea de dois triterpenos bioativos, ácido ursólico e lactona do ácido ursólico em folhas de E. tereticornis. As amostras foram analisadas em coluna RP-18 (4,6 × 250 mm, 5 μm) com metanol e água acidificada a pH 3,5 com TFA (88:12) a 210 nm. O método foi validado e aplicado para a quantificação simultânea dos triter...
متن کاملPharmacology of oleanolic acid and ursolic acid.
Oleanolic acid and ursolic acid are triterpenoid compounds that exist widely in food, medicinal herbs and other plants. This review summarizes the pharmacological studies on these two triterpenoids. Both oleanolic acid and ursolic acid are effective in protecting against chemically induced liver injury in laboratory animals. Oleanolic acid has been marketed in China as an oral drug for human li...
