EVALUATION OF SOME BIOLOGICAL ACTIVITIES FROM (Sphaerocoryne affinis) LEAF EXTRACT FROM PHU QUOC

Abstract

Sphaerocoryne affinis is a medicinal herb known to the people for its many uses. The studies results showed
that the extract had the ability to resist bacterial strains causing disease in aquatic animals with minimum
inhibitory concentration from 80 - 320 μg/mL. At the same time, the effectiveness against 2 fungal strains
Fusarium oxysporum MT453296.1, Lasiodiplodia theobromae JX868613.1 causing diseases on plants was
tested with antifungal efficiency of 85.40%; 92.32%. The extract concentration of 100 μg/mL or more has
the ability to prevent angiogenesis in the chorion of poultry embryos, which had the potential to support the
treatment of cancer. The qualitative chemical composition of the plant containing alkaloids, flavonoids,
saponins, tannins, steroids and triterpenoids contributed to further confirming the results of the above
biological activity evaluation of Sphaerocoryne affinis leaf extract.
