Pentacyclic triterpenes are ubiquitously distributed throughout the plant kingdom, in a free form as aglycones or in combined forms, and have long been known to have a number of biological effects. The compounds-amyrin and -amyrin are commonly found in medicinal plants and oleo-resin obtained by bark incision of several species of Bursera or Protium of the Burseraceae family. Both in vitro a...

Two new long-chain alkanoic acid esters of lupeol were isolated together with known triterpenoids, alpha-amyrin, beta-amyrin, cycloartenol, lanosta-7,24-diene-3beta-ol and lupeol from Alecrim-propolis collected in Brazil. The structures were characterized by spectroscopic means.

Macrolobium acaciifolium belongs to Fabaceae family and only few phytochemical studies were carried out in the scientific literature consulted. The objective of this work was isolate identify secondary metabolites from M. leaves branches hexane extracts, addition evaluate antibacterial potential extracts. plant materials dried extracted with hexane, then methanol water. extracts showed presence...

The simple terpenes, carotenoids, phytosterols, and flavonoids compositions of the leaves of Acalypha wilkesiana were determined by high performance liquid chromatography (HPLC). The leaves were rich in flavonoids (about 251.3mg/kg dry weight), carotenoids (76.3mg/kg dry weight), and phytosterols (16.6mg/kg dry weight), but very low in simple terpenes (0.0084mg/kg dry weight). Three flavonoids ...
