Hepatoprotective effects of the lipid flower pollen extract (LEPK) in paracetamol intoxication in mice were shown. Normalisation of A1AT and LDH--biochemical indicators of necrotic changes in the hepatic cells, and high protection ultrastructural cell organelle such as mitochondrion substantially testifies to the hepatoprotective effect of investigated lipid flower pollen extract on the hepatic...

Many hepatoprotective non-chemical preparations have been recommended as complementary medicine for the treatment of liver disorders. We have utilized a well-defined model of liver injury to study the efficacy of GLU-9599 (a oral bioavailable glutathione-based compound added with selenium, L-cysteine and vitamin C) designed to support liver detox function. Wistar albino rats were divided into f...

This study was designed to determine the antioxidant and hepatoprotective effect of nbutanol soluble fractions of Albizzia lebbeck The various extracts were prepared and extracts containing flavanoids, tannins and saponins (Methanolic extract) was selected for isolation of chemical constituents. nbutanol soluble fractions of extract (BFALB) and leaf extract (BFALL) were selected for screening o...

Triterpenoids are a group of structurally diverse specialized metabolites that frequently show useful bioactivities. These chemicals are biosynthesized from the common precursor 2,3-oxidosqualene in plants. The carbon skeletons produced by oxidosqualene cyclase (OSC) are usually modified by cytochrome P450 monooxygenases (P450s) and UDP-dependent glycosyltransferases. These biosynthetic enzymes...

Triterpenoids are the most promising plant secondary metabolites. Several triterpenoids, including ursolic acid, oleanolic acid, betulinic acid, celastrol, pristimerin, lupeol and avicins are representative group of phytochemicals possesses biological properties. Anti-tumor, anti-cancer, anti-biotic, cytotoxic, anti-inflammatory, anti-HIV, acetyl cholinesterase, anti-wrinkle and antifeedant act...

As a part of our search for hepatoprotective compounds from Lycium chinense fruits, three new pyrrole derivatives (1-3) were isolated. These compounds and a related synthetic methylated compound (4) were evaluated for their biological activity and structure-activity relationship, and compounds 1 and 2 showed hepatoprotective effects comparable to silybin at the concentration of 0.1 microM (64.4...

The hepatoprotective activity of the ethanolic extract of the rhizomes of Costus speciosus (Koenig) Sm. was studied on carbon tetrachloride treated rats. The extract registered a significant fall in the levels of serum glutamyl oxalacetic acid transaminase (SGOT), serum glutamyl pyruvate transaminase (SGPT), alkaline phosphatase (ALKP), serum bilirubin (SBLN) and liver inflammation supported by...

Glycyrrhizae radix et rhizoma has been used as a traditional Chinese medicine for the treatment of various diseases. Triterpenoids and flavonoids from the plant have many beneficial effects and their chemical structures are modified in the gastrointestinal tract after oral administration. However, absorption of these triterpenoids and flavonoids still needs to be defined. Here, the uptake and t...

Antrodia cinnamomea is a precious edible fungus endemic to Taiwan that has long been used as a folk remedy for health promotion and for treating various diseases. In this study, an index of 13 representative metabolites from the ethanol extract of A. cinnamomea fruiting body was established for use in quality evaluation. Most of the index compounds selected, particularly the ergostane-type trit...

We have synthesized more than 80 novel triterpenoids, all derivatives of oleanolic and ursolic acid, as potential anti-inflammatory and chemopreventive agents. These triterpenoids have been tested for their ability to suppress the de novo formation of two enzymes, inducible nitric oxide synthase (iNOS) and inducible cyclooxygenase (COX-2), using IFN-gamma-stimulated primary mouse macrophages or...
