Evaluation of biological activities of Alpinia mutica Roxb. and its chemical constituents
Phytochemicals investigation on rhizomes of Alpinia mutica has afforded five compounds namely 5,6-dehydrokawain (1), flavokawin B (2), pinostrobin (3) and pinocembrin (4) together with β-sitosterol (5). All crude extracts of the plant demonstrated strong cytotoxicity against CEMss (human T4 lympho...

| Summary: | Phytochemicals investigation on rhizomes of Alpinia mutica has afforded five compounds namely 5,6-dehydrokawain (1), flavokawin B (2), pinostrobin (3) and pinocembrin (4) together with β-sitosterol (5). All crude
extracts of the plant demonstrated strong cytotoxicity against CEMss (human T4 lymphoblastoid) cancer cells with IC50 values less than 19 µg/mL, while flavokawin B (2) was the most cytotoxic isolate with IC50 value 1.86±0.37 µg/mL.
Most of the crude extracts and isolated compounds showed weak activity in antimicrobial and diphenylpicrylhydrazyl
(DPPH) radical scavenging activity tests. |
