چکیده

Amorphophallus opertus hett. and a. lanceolatus (serebryanyi) hett. & c. claudel, two members of the araceae family, are recognized as endemic species of vietnam. due to lacking samples of these species, the bioactivity and phytochemicals of these species have not been elucidated yet. this study was firstly investigated the antioxidant capacity and flavoinoid, triterpenoid, polyphenol, polysaccharide contents of a. opertus and a. lanceolatus tubers using spectrophotometric assay (uv-vis) and uvwin6 software v6.0.0, which is important step for further utilization and application of these species. the results showed that a. opertus tuber contained several bioactive compounds, such as flavonoids (0.313 ± 0.009 mg qe/g dry mass), triterpenoids (0.020 ± 0.001 mg oae/g dry mass), polyphenols (0.026 ± 0.001 mg gae/g dry mass), with the polysaccharide content about 1.653 ± 0.157 mg ge/g dry mass, and the strong antioxidant capacity (dpph scavenging activity about 0.027 ± 0.001 mg trolox/g dry mass and abts scavenging activity about 0.017 ± 0.001 mg trolox/g dry mass). on the other hand, a. lanceolatus tuber comprised about flavonoids (0.032 ± 0.004 mg qe/g dry mass), triterpenoids (0.0109 ± 0.0003 mg oae/g dry mass), polyphenols (0.029 ± 0.003 mg gae/g dry mass), with the lower polysaccharide content (0.0131 ± 0.0003 mg ge/g dry mass) amd antioxidant capacity (dpph scavenging activity about 0.017 ± 0.001 mg trolox/g dry mass and abts scavenging activity about 0.012 ± 0.001 mg trolox/g dry mass).
