BACKGROUND Bursera copallifera (Burseraceae) releases a resin known as "copal ancho" which has been used, since pre-Colombian times, as ceremonially burned incense and to treat tooth ache, tumors, arthritis, cold, cough, and various inflammatory conditions; however, its anti-inflammatory potential is poorly studied. The aim of the present study was to isolate, quantify, and to investigate the a...

Forestry biomass is a by-product which commonly ends up being burnt for energy generation, despite comprising valuable bioactive compounds with valorisation potential. Leaves of Acacia dealbata were extracted the first time by supercritical fluid extraction (SFE) using different conditions pressure, temperature and cosolvents. Total yield, individual triterpenoids yields concentrations assessed...

Triterpenoids are a group of structurally diverse specialized metabolites that frequently show useful bioactivities. These chemicals are biosynthesized from the common precursor 2,3-oxidosqualene in plants. The carbon skeletons produced by oxidosqualene cyclase (OSC) are usually modified by cytochrome P450 monooxygenases (P450s) and UDP-dependent glycosyltransferases. These biosynthetic enzymes...

This work describes the phytochemical study of the extracts from aerial parts of Tibouchina candolleana as well as the evaluation of the antimicrobial activity of extracts, isolated compounds, and semi-synthetic derivatives of ursolic acid against endodontic bacteria. HRGC analysis of the n-hexane extract of T. candolleana allowed identification of β-amyrin, α-amyrin, and β-sitosterol as major ...

CYP51 has been recognized as a unique CYP family that consists of one isolated molecular species, a sterol 14-demethylase essential for sterol biosynthesis. However, another CYP51 gene classified as the CYP51H subfamily has been identified in higher plants, in addition to a sterol 14-demethylase gene, CYP51G1. To shed light on the function of this "second CYP51", oat CYP51H10 was introduced int...

Phytochemical analysis of Tanaecium bilabiatum leaf led to the isolation and identification salacinin C, daturadiol a mixture triterpenes, α-amyrin β-amyrin. Besides chemical analysis, methanol extract T. leaf, METBL was evaluated for analgesic, anti-diarrheal hypoglycemic potential in mice model. For analgesic activity test by tail immersion technique, significantly extended percent elongation...

Glycyrrhizin, a major bioactive compound derived from the underground parts of Glycyrrhiza (licorice) plants, is a triterpene saponin that possesses a wide range of pharmacological properties and is used worldwide as a natural sweetener. Because of its economic value, the biosynthesis of glycyrrhizin has received considerable attention. Glycyrrhizin is most likely derived from the triterpene be...

BACKGROUND Hylocereus polyrhizus and Hylocereus undatus are two varieties of the commonly called pitaya fruits, and pitaya fruits have gained popularity in many countries all over the world. However, studies on chemical composition and the nutritional quality of pitaya flesh peel are limited. RESULTS Extracts of pitaya (H. polyrhizus and H. undatus) peel were extracted by supercritical carbon...
