Chrysanthemum (Chrysanthemum morifolium Ramat.), an ornamatal plant, has medicinal, drinking and edible value with an increasing demand for chrysanthemum of mutiple functions for drinking. However, chrysanthemums for tea in China are traditional white varieties, a small amount of yellow, and shape and color are single, so it’s difficult to meet current market demand for diversified, personalized varieties and traditional varieties also have some shortcomings in flowering, production and exterior features after processing. Therefore, total flavonoids,chlorogenic acid content and water extracts were analyzed in some cut chrysanthemums, and the quality evaluation, total flavonoids and chlorogenic acid content in dried chrysanthemums of different inflorescence development stages of different species and varieties were determined to find out new suitable chrysanthemum varieties for Jumi tea、chrysanthemum bud and chrysanthemum tea. The results were as follows:1. Comparison fixation and non-fixation cut chrysanthemum varieties in active ingredients:total average content of total flavonoids,chlorogenic acid and water extracts of fixation varieties were 37.84mg/g,2.332% and 66.65%,which are higher than those in non-fixations (27.69mg/g,1.365% and 61.31%). Compared with the traditional chrysanthemum ’Chu Ju’, the active ingredients content of’Qx-035’,’Froggy’,’Qx-116’, ’Marimo’,’Feeling Green’,’Southern farmers Purple Star’are higher with a sigitnificant difference.We further analyzed the plant yield of six different varieties.Yield per plant of ’Froggy’ is superior to the other five kinds of chrysanthemums, a potential for ornament and tea.2. Suitable to different processing purposes of chrysanthemum tea varieties screening(1) According to the evaluation criteria established for chrysanthemum tea flavor quality (taste, type, petals, color, smell, liquor color, the brewing flower), we screen varieties suitable for the Jumi, Chrysanthemum Bud tea, chrysanthemum tea from 55 samples including 27 kinds of chrysanthemum indicum and 28 kinds of ground cover, Chrysanthemum morifolium, edible chrysanthemum.’ChiHuang’, XiuNing chrysanthemum indicum②, JiangNing chrysanthemum indicum,’Zhe 12’, ’Chrysanthemum morifolium’,’florists chrysanthemum’ were selected as Chrysanthemum meters; And ’ChuJu’,’HangBaiju’,’Shihuang’,’florists chrysanthemum’,’JinLing kuihua’ were selected as Chrysanthemum Buds; There were 5 kinds of chrysanthemum, which includes five kinds of Chrysanthemum morifolium(’Qx-133’,’Qx-175’,’Ibis Sunny, ’Ouyuanbai’,’Ouyuanhuang’); six kinds of filial generation(’L4’,’L15’,’L30-2’,’L34-1’, ’L38’,’L39’); one kind of edible chrysanthemum(’Shihuang’); 3 kinds of ground-cover chrysanthemum(’Jinglingqiuse’,’Jinglingzaobai’,’Jinlingbaifeng’).(2) After the contents of water extract, total flavonoids, chlorogenic acid in screened 26 kinds of chrysanthemum were determined, there were 3 kinds of chrysanthemum selected as Jumi, including’ChiHuang’, XiuNing chrysanthemum indicum②,’Zhe 12’; there were 2 kinds of chrysanthemum selected as Chrysanthemum Buds, including ’Shihuang’,’JinLing kuihua’ were selected as; There were 4 kinds of chrysanthemum selected as Chrysanthemum tea, including’Shihuang’,’Jinglingqiuse’,’Jinlingbaifeng’, ’Lollipop Purple’. The total average amount of total flavonoids Chrysanthemum tea(28.00mg/g)>Jumi (24.66mg/g)>Chrysanthemum Buds (22.27 mg/g),the total average amount of chlorogenic acid Chrysanthemum tea (0.540%)>Jumi (0.528%)> Chrysanthemum Buds (0.423%),the total average amount of water extract Chrysanthemum tea (51.50%)>Chrysanthemum Buds (47.80%)>Jumi (47.54%)...
