Alpha- amylase inhibition activity of methanolic extract of Nyctanthes arbor-tristis flower petals

Now a day’s many people are affected by diabetes- a chronic disorder, treated by using synthetic medicines which needs long-term therapy. To avoid patient inconvenience and side effects, many researchers are getting active ingredients from natural sources. Nyctanthes arbor- tristis, A old traditional plant with number of medicinal values. It is having pharmacological activities like antibacterial, anti-allergy, anti-anxiety, anti-inflammatory, anti-malarial, anti-leishmanial, anti-microbial, anti-parasitic, anti-aggressive, CNS depressant, anti-pyretic, hypoglycemic and hypolipidemic. The purpose of this research work is to find out the antidiabetic activity of Nyctanthes arbor-tristis flower petals. From literature review we found that there was no report on Alpha- amylase inhibition activity of methanolic extract of Nyctanthes arbor- tristis flower petals. The methanolic extraction of Nyctanthes arbor- tristis flower petals having phytochemicals like Flavanoids, glycosides, alkaloids, tannins. we are reporting that the methanolic extraction of Nyctanthes arbor- tristis flower petals have shown potent anti-diabetic activity by inhibiting the Alpha- amylase activity when comparing with standard Voglibose.
