Apoptosis,antimicrobial and antioxidant activities of phytochemicals from Garcinia malaccensis Hk.f

of 0.40μM and 0.48μM,respectively,α-Mangostin was active against Gram-positive bacteria, Staphylococcus aureus（S.aureus） and Bacilus anthracis（B.anthmcis） with inhibition zone and MIC value of（19 mm;0.02S mg/mL） and（20 mm;0.013 mg/mL）,respectively.In antioxidant assay,α-mangostin exhibited activity as an inhibitor of lipid peroxidation.Conclusions:G.malaccenm presenceα- andβ-mangostin and cycloart-24-en-3β-ol.β-Mangostin was found very active against H.SC-3 cells and KS62.The results suggest that mangoslins derivatives have the potential to inhibit the growth of cancer cells by inducing apoptosis.In addition,α-andβ-mangostin was found inhibit the growth of Cram-positive pathogenic bacteria and also showed the activity as an inhibitor of lipid peroxidation.
