In vivo and in vitro antidiabetic studies of Pereskia bleo leaves

Background review Since ancient times, plants have been used as natural agents to treat diseases particularly diabetes whose prevalence is increasing worldwide. Leaves of Pereskia bleo (Jarum Tujuh Bilah) are traditionally used to treat diabetes in many countries including Malaysia, however, no sc...

Leaves of Pereskia bleo (Jarum Tujuh Bilah) are traditionally used to treat diabetes in many countries including Malaysia, however, no scientific claim exists in literature. Objective To investigate in vivo and in vitro antidiabetic activity of P. bleo with respect to understand its role in the management of diabetes. Methods Freeze dried aqueous (AQ) and ethanol (ETOH) extracts of the leaves were examined for in vivo antidiabetic activity (alloxan induced diabetic adult albino male rats of Sprague Dawley strain) and in vitro activity (inhibition of alpha-glucosidase and alpha-amylase enzymes). Two doses (250 and 500 mg/kg body weight) of both extracts were administered orally to the normal and diabetic rats. The blood glucose level of the rats was measured by using glucometer at 0, 2, 4, 6, 8 and 24 h after administering both extracts. For in vitro method, the inhibitory activities of both extracts against α- amylase and α-glucosidase were evaluated at 5 different concentrations (i.e. 50, 100, 250, 500, and 1000 µg/ml). Toxicological study was also performed to know the safe nature of both extracts. Results and Conclusion The acute toxicity study revealed LD50 for the both AQ and ETOH extracts above 2500 mg/kg b.w. Both extracts exhibited a significant antihyperglycemic effect in diabetic rats after 24 h treatment of the extracts without showing hypoglycemic effect in normal rats. The highest blood glucose reduction (from 28.3 to 9.0 mmol/l) in diabetic rats was seen in ETOH extract at 250 mg/kg b.w. after 24 h. For in vitro antidiabetic study, both extracts showed high inhibitory activity against α-amylase. The highest inhibition (99.23%) was seen at 1000 µg/mL by AQ extract. On the other hand, AQ extract did not show inhibitory activity against α-glucosidase and ETOH showed a moderate inhibition (15.46%) against α-glucosidase at 1000 µg/mL. The results from this study further justify the traditional claims of P. bleo in the management of diabetes in Malaysia. 2014-10-16 Conference or Workshop Item REM application/pdf en http://irep.iium.edu.my/41903/1/NADI2.pdf Ahmed, Qamar Uddin and Ahmad, Zulfadliza and Afrin, Mehnaz and Tunna, Tasnuva Sarwar and Ibrahim Apandi, Nur Amalina and Wan Zaini, Wan Norshakirah (2014) In vivo and in vitro antidiabetic studies of Pereskia bleo leaves.
