objective(s):the current study was aimed to determine the bioactive constituents and biological effects of the crataegus monogyna ethanolic extracts from bark, leaves and berries on hypercholesterolemia. materials and methods: oleanolic acid, ursolic acid, quercetin and lupeol concentrations were quantified by hplc. total phenol content and radical scavenging activity of extracts were also meas...

Five new lanostane triterpenoids, ganoderic acid XL1 (1), ganoderic acid XL2 (2), 20-hydroxy-ganoderic acid AM1 (3), ganoderenic acid AM1 (4) and ganoderesin C (5), together with five known triterpenoids (6-10) were isolated from the fruiting bodies of Ganoderma theaecolum. Chemical structures were elucidated on the basis of spectroscopic evidence, including 1D, 2D NMR, mass spectrometric data ...

Inula britannica L., family Asteraceae, is used in traditional Chinese and Kampo Medicines for various diseases. Flowers or the aerial parts are a rich source of secondary metabolites. These consist mainly of terpenoids (sesquiterpene lactones and dimmers, diterpenes and triterpenoids) and flavonoids. The isolated compounds have shown diverse biological activities: anticancer, antioxidant, anti...

Abstract Ganoderma lucidum or Reishi is a medicinal mushroom of significant importance that being used for the prevention and treatment various diseases, due to its numerous pharmacological therapeutic properties. The Ganodermataceae family diverse, but focus on species because specific biologically active macromolecules such as polysaccharides, triterpenoids, steroids, phenolic compounds, lact...

Helicanthes elasticus (Desr.) Danser is a member of family Loranthaceae which found widely growing on mango trees in southern India. Alkaloids, carbohydrate, steroids, tannins, saponins, phenols, flavonoids and triterpenoids are mainly believed to be responsible for its wide therapeutic actions. It known possess medicinal activities such as antimicrobial activity, immunomodulatory hepatoprotect...

Materials and Methods: Oleanolic acid, ursolic acid, quercetin and lupeol concentrations were quantified by HPLC. Total phenol content and radical scavenging activity of extracts were also mea...

Several known triterpenoids have been isolated from the roots of Lantana camara L. along with two new ones namely: 3ß,19α-dihydroxy-ursan-28-oic acid (7) and methyl 21,22ß-epoxy-3ß-hydroxy-olean-12-en-28-oate (8a). The hepatoprotective principle, oleanolic acid (1), from the roots has been converted into its 28-->13ß-lactone 10 by a facile photo-oxidation reaction. The leaves of L. camara have ...

Saponins are secondary metabolites with high molecular weight. They present in a wide range of plant species and are distributed throughout the bark, leaves, stems, roots and even flowers. Saponins are bitter in taste and in recent years, they have received considerable attention because of their various biological activities including hepatoprotective, anti-ulcer, anti-tumor, antimicrobial, ad...

Plumeriaalba and Plumeria acuminate is small laticiferous tree or shrub is a native of tropical America, commonly known as White Champa Leaf and stem were evaluated for its phytoconstituents, which is used in several traditional medicines to cure various diseases. P. accuminata, P. alba, P. rubra, P. lancifolea, P. drastic and P. phagidenica are some of the species with medicinal utility. This ...

Lantadenes are pentacyclic triterpenoids present in the leaves of the plant Lantana camara. In the present study, in vitro antioxidant activity and free radical scavenging capacity of lantadene A was evaluated using established in vitro models such as ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picryl-hydrazyl (DPPH•), hydroxyl radical (OH•), nitric oxide radical (NO•), superoxide ...
