香精是植物酚类物质中最普遍的一类。由于它们在植物和人类健康中的重要性，更好地了解黄酮类化合物的浓度和生物活性将是有用的，这可以表明它们作为治疗剂的潜力，也可以用于预测和控制药材的质量。生姜是一种重要的药用植物，尤其是在亚洲，它含有多种重要的生物活性成分，具有保健作用。本研究从两种药用植物的叶和根茎中提取了总黄酮及槲皮素、芦丁、儿茶素、表儿茶素、山奈酚和柚皮素等黄酮类成分（Halia Bentong和Halia Bara）在三个不同的增长点（种植后8、12和16周），并通过高效液相色谱法（HPLC）进行分析，以确定嫩姜地下部分的潜力。结果表明，海百合叶和根茎中黄酮类化合物的含量高于海百合本通。在这两个品种中，随着生长期的增加，叶中黄酮类化合物的浓度降低（Halia Bentong，42.3%; Halia Bara 36.7%），而根茎中黄酮类化合物的浓度增加（Halia Bentong，59.6%; Halia Bara 60.1%）。槲皮素在两个品种中含量丰富。1，1-二苯基-2-苦基-肼（DPPH）法测定的抗氧化活性表明，在种植后8周，Halia Bara叶片中的抗氧化活性较高（65.7%）。结果表明，生姜叶片中黄酮含量和抗氧化活性潜力在种植后8周。这些生姜品种的叶子可用于食品调味品和传统药物。
Flavonoids make up one of the most pervasive groups of plant phenolics. Due to their importance in plants and human health, it would be useful to have a better understanding of flavonoid concentration and biological activities that could indicate their potentials as therapeutic agents, and also for predicting and controlling the quality of medicinal herbs. Ginger (Zingiber officinale Roscoe) is a famous and widely used herb, especially in Asia, that contains several interesting bioactive constituents and possesses health promoting properties. In this study, total flavonoids and some flavonoid components including quercetin, rutin, catechin, epicatechin, kaempferol and naringenin were extracted from the leaves and rhizomes of two varieties of Zingiber officinale (Halia Bentong and Halia Bara) at three different growth points (8, 12 and 16 weeks after planting), and analyzed by a high performance liquid chromatography (HPLC) method in order to determine the potential of the subterranean part of the young ginger. The results showed that Halia Bara had a higher content of flavonoids in the leaves and rhizomes as compared to Halia Bentong. In both varieties, the concentration of flavonoids in the leaves decreased (Halia Bentong, 42.3%; Halia Bara 36.7%), and in the rhizomes it increased (Halia Bentong 59.6%; Halia Bara 60.1%) as the growth period increased. Quercetin was abundant in both varieties. The antioxidant activity determined by the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) assay showed high activities (65.7%) in the leaves of Halia Bara at 8 weeks after planting. Results suggested a good flavonoid content and antioxidant activity potential in ginger leaves at 8 weeks after planting. The leaves of these ginger varieties could be useful for both food flavourings and in traditional medicine.
