Data on antiplatelet aggregation, anticoagulation and antioxidant activities of Canna edulis Ker rhizome and its secondary metabolites.

Abstract

Canna edulis Ker rhizome has been used in Traditional Vietnamese Medicine to prevent and treat heart diseases without thorough scientific evidence. The data presented in this article characterize the antiplatelet aggregation, anticoagulant and antioxidant activity of C. edulis rhizome extracts and the bio-guided isolation of bioactive compounds from the active fraction. The data on tested bioactivities of isolated compounds were also provided. The inhibitory effect on adenosine diphosphate- and collagen-induced human platelet aggregation was evaluated through three parameters: percentage inhibition of platelet aggregation, aggregation velocity and area under the platelet aggregation curve. Prothrombin time, activated partial thromboplastine time and thrombine time were measured to examine the anticoagulant activity. The free radical scavenging ability was assessed with DPPH and ABTS assays. The structures of compounds were elucidated by NMR and MS spectroscopic methods. The data showed that the ethyl acetate fraction showed the most potent antiplatelet aggregation, anticoagulant and antioxidant activity. Seven known compounds: 5-hydroxy-6-methyl-2H-pyran-2-one (1), epimedokoreanone A (2), nepetoidin B (3), ferulic acid (4), caffeic acid (5), hydroxytyrosol (6), and 1H-indole-3-carboxaldehyde (7) were isolated from this active fraction. Moreover, this article provided experimental data on antiplatelet effect of epimedokoreanone A (2) and nepetoidine B (3), anticoagulant and antioxidant activity of epimedokoreanone A (2) and also antiplatelet and antioxidant activity of 5-hydroxy-6-methyl-2H-pyran-2-one (1).
