Induced isoflavonoids from fungus-infected stems of pigeon pea (Cajanus cajan).
Four antifungal isoflavones [7-hydroxy-4'-methoxy-(1); 5,7,4'-trihydroxy-(2); 5,7,2',4'-tetrahydroxy-(3); 5,2',4'-trihydroxy-7-methoxy-(4)] and one isoflavanone [(5,2'-dihydroxy-7,4'-dimethoxy-(7)] have been isolated from the fungus-infected stems of Cajanus cajan. A sixth compound has been provisionally identified as 5,2'-dihydroxy-7,4'-dimethoxyisoflavone (5). The structure of 5,2'-dihydroxy-...
متن کاملPurification and Characterization of Glucose-6-Phosphate Dehydrogenase from Pigeon Pea (Cajanus cajan) Seeds
Glucose-6-phosphate dehydrogenase has been purified from pigeon pea (Cajanus cajan) seeds and subjected to characterization. The enzyme was purified 123.69 fold with a yield of 21.37% by ammonium sulphate fractionation, PEG-4000 precipitation, CM cellulose column chromatography and DEAE cellulose column chromatography. The catalytically active enzyme is a dimer of 113 KDa with a subunit molecul...
متن کاملCharacterization of Five Fungal Endophytes Producing Cajaninstilbene Acid Isolated from Pigeon Pea [Cajanus cajan (L.) Millsp.]
Five fungal endophytes (K4, K5, K6, K9, K14) producing Cajaninstilbene acid (CSA, 3-hydroxy-4-prenyl-5-methoxystilbene-2-carboxylic acid) were isolated from the roots of pigeon pea [Cajanus cajan (L.) Millsp.]. CSA is responsible for the prominent pharmacological activities in pigeon pea. The amount of CSA in culture solution varied among the five fungal endophytes. K4 produced the highest leve...
متن کاملGerminated Pigeon Pea (Cajanus cajan): a novel diet for lowering oxidative stress and hyperglycemia
This work studied the antioxidant activity of extract of germinated pigeon pea (Cajanus cajan) in alloxan-induced diabetic rats. Germination was carried out in a dark chamber under room temperature (28°C). The total phenolic, 1,1,diphenyl-2-picrylhy-drazyl free radical (DPPH) scavenging, the inhibition of α-amylase and α-glucosidase were done in vitro and blood glucose levels of the animal were...
متن کاملEffect of gamma irradiation on physicochemical properties of stored pigeon pea (Cajanus cajan) flour
The effect of gamma irradiation at various doses (5, 10, 15, 20 kGy) was observed on pigeon pea flour stored for 3 months on proximate composition, functional properties, and peroxide value. Sensory evaluation was also carried out on bean cake (moinmoin) made from nonirradiated and irradiated pigeon pea flour. The results showed that stored gamma-irradiated samples had significantly lower (P < ...
