Mangifera foetida L. (Macang) source of potent antiviral activity of against Dengue Virus serotype 2 (Anti DENV2)

Abstract

The new discovery about the potential of Mangifera foetida L. as an antiviral will help conservation efforts in nature while maintaining and increasing its biodiversity value. This study aims to characterize the in vitro potential of three varieties of M. foetida L. against the dengue virus. Dengue virus is infected in Vero cells, viral replication was measured using the Viral ToxGlo Assay method. The selectivity ability of Mangifera foetida L. stem bark extract to inhibit the dengue virus was seen from the Selectivity Index (SI) value. The standard curve between the concentration of the compound (μg/mL) and % cell viability was analyzed by linear regression using Microsoft Excel 2010 software. The results showed that the selectivity index (SI) value of M. foetida L stem bark extract of Limus, Manis and Batu varieties were 7.58, 6.82 and 16.43, respectively. It was concluded that the extract of Macang stem bark of the Limus, Manis and Batu varieties had the potential to be used as an antiviral for dengue.
