生姜（Zingiber officinale Roscoe）是一种众所周知的广泛使用的草药，特别是在亚洲，它含有几种有趣的生物活性成分，具有促进健康的特性。本研究对两个药用姜品种（Halia Bentong和Halia Bara）的叶、茎和根茎甲醇提取物的抗氧化活性进行了评估，以比较和验证年轻姜地下部分的药用潜力。DPPH法测定其抗氧化活性、酚类物质含量、总酚类物质和总黄酮含量均高于根茎和茎。另一方面，根状茎的铁还原/抗氧化电位（FRAP）活性高于叶片。在低浓度下，两个品种叶片的抑菌活性值均显著高于或与幼根茎相当。与海棠相比，巴拉具有更高的抗氧化活性以及总酚和类黄酮含量。本研究验证了生姜叶和幼根的药用潜力，以及生姜总酚含量与抗氧化活性之间的正相关关系。
Ginger (Zingiber officinale Roscoe) is a well known and widely used herb, especially in Asia, which contains several interesting bioactive constituents and possesses health promoting properties. In this study, the antioxidant activities of methanol extracts from the leaves, stems and rhizomes of two Zingiber officinale varieties (Halia Bentong and Halia Bara) were assessed in an effort to compare and validate the medicinal potential of the subterranean part of the young ginger. The antioxidant activity and phenolic contents of the leaves as determined by the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay and the total amounts of phenolics and flavonoids were higher than those of the rhizomes and stems. On the other hand, the ferric reducing/antioxidant potential (FRAP) activity of the rhizomes was higher than that of the leaves. At low concentration the values of the leaves’ inhibition activity in both varieties were significantly higher than or comparable to those of the young rhizomes. Halia Bara had higher antioxidant activities as well as total contents of phenolic and flavonoid in comparison with Halia Bentong. This study validated the medicinal potential of the leaves and young rhizome of Zingiber officinale (Halia Bara) and the positive relationship between total phenolics content and antioxidant activities in Zingiber officinale.
