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 کاملSonchus asper extract inhibits LPS-induced oxidative stress and pro-inflammatory cytokine production in RAW264.7 macrophages
BACKGROUND/OBJECTIVES Sonchus asper is used extensively as an herbal anti-inflammatory for treatment of bronchitis, asthma, wounds, burns, and cough; however, further investigation is needed in order to understand the underlying mechanism. To determine its mechanism of action, we examined the effects of an ethyl acetate fraction (EAF) of S. asper on nitric oxide (NO) production and prostaglandi...
متن کاملComparison of the Nutritive Value, Antioxidant and Antibacterial Activities of Sonchus asper and Sonchus oleraceus
Many local vegetable materials are under-exploited because of inadequate scientific knowledge of their nutritional potentials. For this reason, the nutritional, phytochemical, antioxidant and antibacterial activities of the acetone, methanol and water extracts of the leaves of Sonchus asper and Sonchus oleraceus were investigated. The proximate analysis showed that the plants contained apprecia...
متن کاملEvaluation of the Chemical Composition of Sonchus eruca and Sonchus asper
Sonchus eruca and Sonchus asper were analyzed for their chemical evaluation, vitamins and bioactive secondary metabolite. The results revealed the presence of bioactive constituents comprising alkaloids (1.24 to 1.34 mg/100 g), saponins (1.46 to 1.72 mg/100 g), flavonoids (1.61 to 1.34mg/100 g), phenols (1.32 to1.44 mg/100g), saponins (0.12 to 0.41mg/100 g) and tannins (0.02 to 0.61 mg/100g). T...
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...
