(L.) Steane & Mabb. a plant having significant medicinal value is used in treating a fever, rheumatism, inflammation, pain, and malarial fever. Ursolic acid has a five-ringed pentacyclic structure belongs to the family of triterpenoids. It has antioxidant, antitumor, and hepato-protective properties. The method in HPLC was developed on a SHIMADZU, Shimpack ODS (25 cm × 4.6 mm, 5 µm) column. The mobile phase consisted of a 70:25:5 (v/v/v) mixture of methanol, acetonitrile, and 0.02 M ammonium acetate buffer (pH 3.5). A flow rate of 1.2 mL/min and λ of 215 nm. Ursolic acid from the extract and standard was eluted at the same retention time of 4.1 min. 20-120 µg/mL was the linearity range chosen and was found to be linear (=0.996). The value of LOD was 0.85 µg/mL and LOQ was 1.96 µg/mL. The method for analysis of ursolic was found to be accurate with good repeatability.

Background: Periodontitis, a chronic inflammatory disease, poses challenges in treatment due to its complex etiology. Tripterygium glycosides (TGs), renowned for their immunosuppressive and anti-inflammatory capabilities, present a prospective therapeutic option for the management of periodontitis. This study delves into the therapeutic efficacy of TGs in periodontitis and reveals the fundamental mechanisms involved.

Active herbal ingredients are gaining recognition for their potent anti-tumor efficacy, attributable to various mechanisms including tumor cell inhibition, immune system activation, and tumor angiogenesis inhibition. Recent studies have revealed that numerous anti-tumor herbal ingredients, such as ginsenosides, ursolic acid, oleanolic acid, and Angelica sinensis polysaccharides, can be utilized to develop smart drug carriers like liposomes, micelles, and nanoparticles. These carriers can deliver active herbal ingredients and co-deliver anti-tumor drugs to enhance drug accumulation at tumor sites, thereby improving anti-tumor efficacy.

This study aimed to assess how ursolic acid (UA) can protect human skin keratinocytes from damage caused by ultraviolet B (UVB) radiation. Utilizing an omics-based approach, we characterized the features of photodamage and investigated the potential of UA to reverse HaCaT cell subpopulation injury caused by UVB radiation. The most significant changes in metabolite levels after UA treatment were in pathways associated with phosphatidylcholine biosynthesis, arginine and proline metabolism.

Objectives: In the present study, we investigate the effect of FeO nanoparticles conjugated with ursolic acid (FeONPs@UA) on inhibiting the growth, biofilm-forming ability and efflux pump activity in clinical isolates of Pseudomonas aeruginosa with multiple drug resistance.
Methods: Iron oxide NPs conjugated with ursolic acid (FeONPs@UA) were synthesized. Physicochemical features of the NPs were studied by FT-IR, XRD, EDAX, and TEM.
