The various kinds of phytochemicals were detected and then &lt;em&gt;in vitro&lt;/em&gt; antidiabetic activity of &lt;em&gt;P. guajava &lt;/em&gt;were detected by using alpha amylase and alpha glucosidase enzyme in an &lt;em&gt;in vitro&lt;/em&gt; model. &lt;strong&gt;Results:&lt;/strong&gt; The study reveals the presence of phytochemicals such as carbohydrate, tannin, flavonoids, phenols etc., Among the various extracts the aqueous and ethanolic extracts which contains the large number of phytoconstituents. The &lt;em&gt;P. guajava &lt;/em&gt;leaves has been successfully inhibited both the enzymes in an &lt;em&gt;in vitro&lt;/em&gt; model. The aqueous extracts of &lt;em&gt;P. guajava&lt;/em&gt; leaves inhibited the alpha amylase and alpha glucosidase enzymes as 72.1% and 74.8% respectively. The ethanolic extract of &lt;em&gt;P. guajava &lt;/em&gt;leaves inhibited the alpha amylase and alpha glucosidase enzymes as 97.5% and 91.8% respectively. &lt;strong&gt;Conclusion:&lt;/strong&gt; From the results obtained in the current studies, the &lt;em&gt;P. guajava &lt;/em&gt;leaves have a prominent antidiabetic property in an &lt;em&gt;in vitro&lt;/em&gt; model and further studies can be carried out in an &lt;em&gt;in vivo&lt;/em&gt; model and the isolation of activie compound from&lt;em&gt; P. guajava &lt;/em&gt;leaves extract is needed&lt;em&gt;.&lt;/em&gt;&lt;/p&gt;

Antioxidant assay is performed by DPPH, ABTS and FRAP assay, Anti diabetic activity was determined by modified method of miller, the extract at different concentrations was tested for mammalian alpha amylase and alpha glucosidase enzyme inhibitory assay under the controlled experimental conditions and subjected to determination of absorbance. &lt;strong&gt;Results: &lt;/strong&gt;The present study reveals the presence of few secondary metabolites and the extract exhibits potent Antioxidant activity and a concentration dependent inhibition of Alpha amylase and Alpha glucosidase.&lt;strong&gt; Conclusion:&lt;/strong&gt; From the present study it can be concluded that ethanolic seed extract of Acacia catechu possessed marked in vitro antioxidant and anti-diabetic effect. The effect was plausibly due to the presence of phenolic contents of Acacia catechu&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">356</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Thangavelu Lakshmi&lt;sup&gt;*1&lt;/sup&gt;, Rajendran Ramasamy&lt;sup&gt;2&lt;/sup&gt; and Rathinam Thirumalaikumaran&lt;sup&gt;3&lt;/sup&gt; &lt;/strong&gt;&lt;sup&gt;1&lt;/sup&gt;Department of Pharmacology, Saveetha Dental College and Hospitals, Chennai, India. 2Department of R and D, Green Chem Herbal Extracts and Formulations, Bangalore, India. 3Department of Pharmacognosy, Faculty of Pharmacy, Sree Ramachandra Medical College and Research Institute, chennai, India.&lt;/p&gt;</style></auth-address></record></records></xml>
