摘要
凉茶因其保健功效而被广泛饮用。在这项研究中，分析了六种市售 Banaba（Lagerstroemia speciosa）和 sambong（Blumea balsamifera）凉茶的酚含量和抗氧化能力。采用 DPPH 和 ABTS 法测定了抗氧化活性，结果表明 L. speciosa 茶的抗氧化活性高于 B. balsamifera 茶。酚含量采用 Folin-Ciocalteu 法测定，结果显示酚含量与抗氧化活性直接相关。根据单位酚含量和抗氧化活性，网上销售的不同品牌茶叶的市场价格差异很大，这表明需要对所分析的茶叶进行更好的质量控制。孟加拉 J.

Phenolic content and antioxidant capacity of Lagerstroemia speciosa (Banaba) and Blumea balsamifera (Sambong) herbal teas sold on-line in the Philippines: A cost-effectiveness analysis
Herbal teas are widely consumed for their health benefits. In this study, the phenolic content and antioxidant capacity of six commercially available banaba (Lagerstroemia speciosa) and sambong (Blumea balsamifera) herbal teas were analyzed. The antioxidant activity was measured using DPPH and ABTS assays, with L. speciosa teas exhibiting higher activity than B. balsamifera teas. The phenolic content was determined using the Folin-Ciocalteu method and showed a direct correlation with antioxidant activity. The market prices based on unit phenolic content and antioxidant activity varied widely with different brands sold online indicating the need for better quality control of the teas analyzed.
