• Extract
  • Our previous studies have reported several functions and their molecular mechanisms of E. japonica leaf extract and triterpenes contained in the extract. (omicsonline.org)
  • In this review article, we focus on the effects of E. japonica leaf extract and triterpenes on inflammatory mediators, proliferation of cancer cells, and ghrelin production. (omicsonline.org)
  • In this note chromatograms generated using UV and Corona CAD detection are compared, and the assay of triterpene content in a Centella asiatica extract sample using the Corona CAD detector is shown. (selectscience.net)
  • Another important active compound that has been shown to possess anticancer effects is alpha-hederin, a pentacycline triterpene and a saponin, which is water soluble perhaps the major active component in the aqueous extract of N. sativa. (wikipedia.org)
  • novel
  • Functional characterization of oxidosqualene cyclases allows improved understanding on how these proteins guide catalytic reactions and how protein-substrate interactions affect the reaction outcome, as well as identification of triterpenes with novel structures and stereochemistry. (rice.edu)
  • Among them, novel biological properties of triterpenes, such as the attenuation of glycosylated serum protein, total cholesterol, and triglyceride level in diabetic mice have been reported [ 3 ]. (omicsonline.org)
  • fruits
  • Results showed that triterpenes could be detected in eight vegetables and six fruits. (biomedsearch.com)
  • In a paper on triterpenes, the ingested fruits are noted to have a "paralyzing effect" on birds. (wikipedia.org)
  • The AMA Handbook of Poisonous and Injurious Plants reports that the triterpenes found in the fruits can result in irritation of the throat, gastroenteritis, diarrhea, and vomiting Like most other members of the Anacardiaceae, Brazilian pepper contains active alkenyl phenols, e.g., urushiol, cardol, which can cause contact dermatitis and inflammation in sensitive individuals.

  • describes
  • The present study describes the leishmanicidal and trypanocidal activities of two quinonemethide triterpenes, maytenin ( 1 ) and pristimerin ( 2 ), isolated from Maytenus ilicifolia root barks (Celastraceae). (mdpi.com)
  • This thesis also describes the first enzyme (camelliol C synthase, CAMS1) that efficiently blocks B-ring formation to make a monocyclic triterpene camelliol C. Phylogenetic analysis reveals that this cyclase has evolved from enzymes that generate pentacycles, and sequence comparison between oxidosqualene cyclases with different catalytic functions allowed for identification of key residues that increases steric bulk in the active site to promote monocycle formation. (rice.edu)
  • Finally, this thesis describes an enzyme arabidiol synthase (PEN1) that produces the tricyclic triterpene diol arabidiol. (rice.edu)
  • sometimes
  • These sugars can be cleaved off in the gut by bacteria, sometimes allowing the aglycone (triterpene) to be absorbed into the bloodstream or to insert into cell membranes. (wikipedia.org)
  • total
  • The total triterpenes of E. japonica leaves reduced the production of inflammatory cytokines from alveolar macrophages through inhibition of nuclear factor-κB (NF-κB) activation in a rat model of chronic bronchitis [ 4 ]. (omicsonline.org)
  • activity
  • The quinonemethide triterpenes 1 and 2 exhibited a marked in vitro leishmanicidal activity against promastigotes and amastigotes with 50% inhibitory concentration (IC 50 ) values of less than 0.88 nM. (mdpi.com)
  • Graminha, M.A.S. Antiprotozoal Activity of Quinonemethide Triterpenes from Maytenus ilicifolia (Celastraceae). (mdpi.com)
  • example
  • A clear example would be the European White Elm Ulmus laevis which, while having little or no genetic resistance to DED, synthesizes a triterpene, Alnulin, rendering the bark distasteful to the vector beetles, obliging them to look further afield for more suitable elms. (wikipedia.org)
  • forms
  • These data support that these triterpenes could be absorbed and deposited in their intact forms, which in turn exerted in vivo anti-oxidative protection. (biomedsearch.com)
