Changes in some liver enzymes in streptozotocin-induced diabetic rats fed sapogenin extract from bitter yam (Dioscorea polygonoides) or commercial diosgenin.
The effects of steroidal sapogenin extract from bitter yam or commercial diosgenin on liver enzyme changes were investigated Diabetic male Wistar rats were fed diets supplemented with 1% steroidal sapogenin extract or commercial diosgenin for three weeks. Plasma glucose levels and the activities of hepatic glucose-6-phosphatase, pyruvate kinase and glucose-6-phosphate dehydrogenase were assesse...
متن کاملDiosgenin contents and DNA fingerprint screening of various yam (Dioscorea sp.) genotypes.
In addition to the importance of many Dioscorea species (yams) as starchy staple food, some representatives are known and still used as a source for the steroidal sapogenin diosgenin, which, besides phytosterols derived from tall-oil, is an important precursor for partial synthesis of steroids for pharmaceutical research and applications. While in edible yams the diosgenin content should be as ...
متن کاملExtraction of Diosgenin, a Bioactive Compound from Natural Source Dioscorea alata Var purpurae
Diosgenin (Figure 1) is a bioactive steroidal sapogenin belonging to the triterpene group and is of great interest to the pharmaceutical industry [1]. It is the aglycone formed by the hydrolysis of saponin dioscin (Figure 1), a compound found in Dioscorea spp. [2]. It serves as an important starting material for the production of corticosteroids, sexual hormones, oral contraceptives as well as ...
متن کاملAnti- trachea inflammatory effects of diosgenin from Dioscorea nipponica through interactions with glucocorticoid receptor α
Asthma is a heterogeneous disease characterized by symptoms of chronic inflammation and airway structural and functional changes. It affects about 300 million people worldwide and causes 250 000 deaths annually, but its symptoms can be greatly relieved by regular use of inhaled glucocorticoids (GCs). GCs exert their function through interacting with glucocorticoid receptors (GRs). Diosgenin is ...
متن کاملEnhancement of diosgenin production in Dioscorea zingiberensis cell cultures by oligosaccharides from its endophytic fungus Fusarium oxysporum Dzf17.
The effects of the oligosaccharides from the endophytic fungus Fusarium oxysporum Dzf17 as elicitors on diosgenin production in cell suspension cultures of its host Dioscorea zingiberensis were investigated. Three oligosaccharides, DP4, DP7 and DP10, were purified from the oligosaccharide fractions DP2-5, DP5-8 and DP8-12, respectively, which were prepared from the water-extracted mycelial poly...
