Pentacyclic triterpenoids from olive fruit and leaf.
This work establishes a new procedure for the extraction and analysis of pentacyclic triterpenes, with which fruits and leaves from three Spanish olive cultivars ("Picual", "Hojiblanca", and "Arbequina") has been studied. The leaf contains important amounts of oleanolic acid (3.0-3.5% DW), followed by significant concentrations of maslinic acid and minor levels of ursolic acid, erythrodiol, and...
متن کاملPentacyclic triterpenoids from the medicinal herb, Centella asiatica (L.) Urban.
Centella asiatica accumulates large quantities of pentacyclic triterpenoid saponins, collectively known as centelloids. These terpenoids include asiaticoside, centelloside, madecassoside, brahmoside, brahminoside, thankuniside, sceffoleoside, centellose, asiatic-, brahmic-, centellic- and madecassic acids. The triterpene saponins are common secondary plant metabolites and are synthesized via th...
متن کاملTranscriptional Profiles of the Response of Methicillin-Resistant Staphylococcus aureus to Pentacyclic Triterpenoids
Staphylococcus aureus is an important human pathogen in both hospital and the community that has demonstrated resistance to all currently available antibiotics over the last two decades. Multidrug-resistant isolates of methicillin-resistant S. aureus (MRSA) exhibiting decreased susceptibilities to glycopeptides has also emerged, representing a crucial challenge for antimicrobial therapy and inf...
متن کامل[Synthesis, physicochemical and pharmacological properties of pentacyclic alkaloid-analogues].
Quinazolinocarboline rutaecarpine and evodiamine (Evodia rutaecarpa) are main alkaloid components of traditional Chinese folk-remedies. Evodiamine exhibited selective antitumor and antimetastatic effects on several cancer cell lines and became lead structure of anticancer agents. During our synthetic research we achieved to gain alkaloid hybrid derivatives by combining the structural elements o...
متن کاملExploring the Chemical Diversity of Algerian Plants: Three New Pentacyclic Triterpenoids from Launaea acanthoclada Roots.
The chemical study of Launaea acanthoclada from South-East Algeria led to the isolation of twelve oxygenated terpenoid compounds, including three new pentacyclic triterpenoids 1-3 with either lupane or ursane rearranged skeletons. The structure and the stereochemistry of these compounds were established by spectroscopic methods, including NMR techniques. The chemical pattern of L. acanthoclada ...
