Abstract

Objective : The evaluation of antidiabetic activity of alcoholic and aqueous extracts of whole plant of Daemia extensa R Br. Materials and methods: The antidiabetic activity of both the extracts were evaluated using alloxan (120 mg/kg; i.p.) induced hyperglycemic rats. The potency of alcoholic and aqueous extracts were compared with that of reference drug chlopropamide. The blood glucose level was measured by using glucometer. Results: The alcoholic extract produced a highly significant fall in Blood Glucose Level (BGL) at 1 h after a single dose of the extract and in prolong treatment (i.e. for a week) the antidiabetic activity was maintained at par with the reference drug chlopropamide. Aqueous extract possess antidiabetic activity which was maintained upto 3 hours after a single dose and later the activity decreases but upon prolonged treatment, the peak activity was found on second day. Conclusion: Alcoholic extract of D. extensa is almost equipotent to chlorpropamide. This qualifies it to be used in ethnomedical diabetic management.

Abstract

A field experiment was carried out during 2010 and 2011 seasons on seven year old Sharbati cultivar of peach, growing in clay loam soil. The experiment was laid out in randomized block designed to study the effect of foliar spraying of boron, zinc and iron and its combination on fruit growth pattern, yield and yield attributing characters of the low-chill peach. Boric acid (0.1%), zinc sulphate (0.5%) and ferrous sulphate (0.5%) were used as a source of boron, zinc and iron, respectively. All the trees were fertilized with same NPK dose as per recommendation. The spraying was done twice; during last week of February, i.e., after petal fall stage and again at 15 days after the first spraying during both years in three replicates. The result revealed that foliar spraying of peach trees with 0.1 % H3BO3 + 0.5 % ZnSO4, 7H2O + 0.5 % FeSO4, 7H2O was the promising treatment for improvement of fruit growth, fruit length, fruit diameter, fruit volume and firmness of the fruit. This treatment was also found best for maximum fruit retention, average fruit weight as well as the fruit yield.
