Comparative Study on Sensory Quality and Bioactive Components of Traditional Chrysanthemum (Duoju) and TaijuZhou Li, Gong Jia, Duan Ying, Wang Bin*R D Department, Hangzhou Efuton Tea Co., LTD (Hangzhou 310052)传统杭白菊（朵菊）和胎菊的品质比较周丽，龚佳，段莹，王斌*杭州艺福堂茶业有限公司研发中心（杭州 310052）摘 要 从感官品质和活性成分含量两个方面评价两种不同花期的杭白菊 (朵菊和胎菊) 的品质差异。通过茶叶常规审评的方法对两种不同花期杭白菊的感官品质进行比较; 利用高效液相色谱法 (HPLC) 测定绿原酸、木犀草苷、3, 5-O-二咖啡酰基奎宁酸的含量; 利用紫外分光光度法对两种不同花期杭白菊的总黄酮含量进行测定和比较; 利 用重量法对两种不同花期杭白菊的水浸出物、挥发油含量进行测定和比较。两种不同花期杭白菊的感官品质和主 要活性成分存在显著差异。胎菊 (花蕾期采摘) 的感官品质优于朵菊 (全菊期采摘), 且其各主要活性成分的含量也 显著高于朵菊。杭白菊更适于在花蕾期 (胎菊) 采摘饮用, 饮用菊市场对胎菊的热捧有其科学性。关键词 杭白菊; 胎菊; 感官品质; 活性成分 AbstractThe difference of sensory quality and bioactive components of two different flowering chrysanthemum werestudied. The sensory quality of the two different flowering chrysanthemum with the common organoleptic method werecompared; chlorogenic acid, luteolin and (-)-3,5-Dicaffeoyl quinic acid concentration of the chrysanthemum flower extract by HPLC were measured; the total flavonoids content of the two different flowering chrysanthemum were measured and compared by UV spectrophotometry method; water extracts, essential oil of the two different flowering Chrysanthemum were determined and compared with weight method. There was a significant difference between sensory quality and bioactive components of the two different flowering Chrysanthemum. The sensory quality of Taiju (picked in bud period) was better than Duoju (picked in full flowering period). Considering the sensory quality and bioactive components, the stage of bud period (Taiju) was the best harvesting time.Keywords Chrysanthemum; Taiju; sensory quality; bioactive components杭白菊为菊科植物菊（Chrysanthemum morifolium Ramat.）的干燥头状花序，为“浙八味”之一，与滁 菊、亳菊、贡菊一起被收载于《中国药典》2010版[1-2]。 杭白菊不仅具有很高的营养价值，而且具有很强的药 用功效。传统中医理论认为，菊花具有散风清热、平 肝明目的功效，可用于治疗风热感冒、目赤昏花、疔 疮肿毒等证[2]。现代药理学研究证明，杭白菊具有抗 菌、抗氧化、清除体内自由基、降血脂、抗心血管疾 病等功效[3-4]。此 外，亦有菊花中的金合欢素-7-O- B-D吡喃半乳糖苷具有抑制艾滋病毒、β-榄香烯具有 抗肿瘤效果的报道[5-6]。 杭白菊主产于浙江桐乡，迄今已有370多年栽培历 史，古时因主要集散地为杭州且花色泛白而得名[7]。
