Abstract

Etlingera elatior Jack. (bunga kantan) dianalisis dari segi komposisi kimia dan ciri biologi (antioksidan dan antimikrob) bagi mengenalpasti potensinya sebagai sumber nutraseutikal. Penilaian dijalankan dengan menggunakan sistem pelarut yang berbeza [metanol, aseton (50%, 90% dan 100% v/v) dan air suling] untuk mengekstrak beberapa komponen antioksidan (jumlah fenol, tanin, flavonoid, dan antosianin) dan aktiviti antioksidan (peratus DPHH aktiviti perencatan radikal dan kuasa penurunan asei antioksidan ferik (FRAP)). Inflorescence of Etlingera elatior Jack. (torch ginger/ kantan) was evaluated for its chemical composition and biological properties (antioxidant and antimicrobial) to assess this plant material as a source of nutraceutical. Using different solvent systems [methanol, acetone (50%, 90% and 100% v/v) and distilled water] the extractability of some of the antioxidant compounds (total phenols, tannins, flavonoids, anthocyanins) and antioxidant activity (percent DPPH radical scavenging activity and ferric reducing antioxidant power (FRAP)) were evaluated.
