The present invention provides a beverage comprising: (a) 0.05 to 10% by weight (wt %) of a chlorogenic acids family mixture comprising isochlorogenic acids(s) family wherein the weight content of said isochlorogenic acid(s) ranges from 1 / 20 to 1 / 3 of the total ingredient (a); (b) hydroxycarboxylic acid(s) in a quantity ranging from 5 to 30 times the weight content of said ingredient (a) and from 0.25 to 10 wt % of the beverage, and / or vegetable-derived or fruit-derived flavor substance(s) in a quantity ranging from 0.1 to 30 times the weight content of said ingredient (a) and from 0.25 to 10 wt % of the beverage; and (c) 30 to 99.7 wt % of water. The present invention provides a flavorous beverage having a stable antihypertensive action and long-term storage stability.

The invention relates to an industrial method for synchronously preparing stevia rebaudiana chlorogenic acid and stevioside. The industrial method includes carrying out alcohol extraction on stevia rebaudiana which is used as a raw material, and then adjusting feed liquid states to allow chlorogenic acid to be in free molecular states; carrying out extraction separation by water-insoluble moderate-polarity organic solvents; enriching the stevia rebaudiana chlorogenic acid on organic layers; enriching the stevioside on water layers. Compared with the traditional water extraction processes, theindustrial method has the advantages that chlorogenic acid components in the stevia rebaudiana can be prevented from being hydrolyzed, so that the contents and effects of effective components in stevia rebaudiana chlorogenic acid products can be guaranteed; effective separation can be carried out on the premise that the quality and the production efficiency of stevioside products are unaffected, the production efficiency can be greatly improved, and the proportion of isochlorogenic acid in the obtained products is close to the proportion of isochlorogenic acid in the raw material; production water consumption can be reduced to a great extent, discharge of sewage and flocculation residues can be decreased, accordingly, the industrial method is a green production process with high benefits,and the progress of the industry can be promoted to a great extent.

The invention discloses a quality control method for simultaneous realization of content analysis and similarity evaluation of 18 components in Ilex kudingcha. Rutin, isochlorogenic acid A and kudinoside A are used as internal references; correction factors of rutin for 6-hydroxy-7,7a-dihydro-2(6H)-benzofuran and hydroxytyrosol glucoside, correction factors of isochlorogenic acid A for protocatechuic acid, kudinoside E, kudinoside D, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, caffeic acid, isochlorogenic acid B, and isochlorogenic acid C, and correction factors of kudinoside A for latifoloside G, kudinoside G, ilex kudingcha ilexoside T and latifoloside H are calculated, and the factors are used as constants for determining content. Only three common reference substances are needed for simultaneous determination of contents of 18 kinds of components in ilex kudingcha, quality of the ilex kudingcha can be rapidly, economically and scientifically controlled, and further cluster analysis, main component analysis and similarity calculation of medicinal materials can be carried out by using contents of the 18 kinds of components, in order to comprehensively control quality of ilex kudingcha.
