Summary: | Plants contain a large number of phytochemical components, many of which are known as bioactive compounds and responsible for the expression of various pharmacological activities. The extract of
fruit collected in Vietnam was investigated for its total phenolic and total flavonoid contents using methanol solvent and different fractions of
fruits (hexane, ethyl acetate, n-butanol, and aqueous). GC-MS analysis was conducted to identify the bioactive chemical constituents occurring in the active extract. Further, the antibacterial activity was tested in vitro on bacterial isolates, namely
,
, and
, using the disc diffusion method on tryptic soya agar (TSA) medium. The methanol extract showed high total flavonoid (82.3 ± 0.41 mg QE/g extract) and phenolic (41.0 ± 0.34 mg GAE/g extract) content. GC-MS of the methanol extract and different fractions of
fruits detected 20 compounds, principally fatty alcohols, fatty acids, phenols, lipids, terpenes derivatives, and carboxylic acids derivatives. A 50 mg/ml concentration of methanol extract had the strongest antibacterial activity on
,
, and
. Furthermore, ethyl acetate, aqueous, and n-butanol fractions inhibited
and
the most. The results of the present study suggested that the fruits of
are rich sources of phenolic compounds that can contribute to safe and cost-effective treatments. |
