The present invention relates to a method for isolating trilobatin and phlorizin from leaves of lithocarpus litseifolius. The method comprises: S1, mixing leaves of lithocarpus litseifolius with an organic solvent at 70-90°C multiple times for reflux extraction or ultrasonic extraction to obtain an extract solution; S2, removing an organic solvent in the extract solution obtained in step S1 to obtain a crude extract of lithocarpus litseifolius, mixing the crude extract of lithocarpus litseifolius with water at 80-100°C for a reflux reaction, and then performing filtering to obtain a first filtrate; S3, crystallizing the first filtrate obtained in step S2, and performing suction filtration to obtain a second filtrate and a crude product of trilobatin; and S4, subjecting the second filtrate obtained in step S3 to a macroporous resin column, eluting same with ethanol, and then recrystallizing same to obtain phlorizin. According to the method, the trilobatin and the phlorizin can be obtained at the same time, and the recovery rate of the trilobatin and the phlorizin reaches 93% or more.
A method for separating active ingredients from Siraitia grosvenorii flowers, comprising: S1, extracting Siraitia grosvenorii flowers with water vapor to obtain wet flowers and a first extracting solution; S2, extracting the wet flowers with ethanol as a solvent at 25-65°C to obtain a second extracting solution and a first filter residue, concentrating the second extracting solution, and performing solid-liquid separation to obtain a third extracting solution and a wet residue; S3, concentrating the third extracting solution, and standing to obtain a crystal and a crystallization mother liquor; and S4, eluting a macroporous adsorption resin chromatographic column on the crystallization mother liquor sequentially with an acid solution, an alkali solution, and an alcohol solution to respectively obtain an acid eluent, an alkali eluent, and an alcohol eluent. According to the method, essential oil, flower dew, polysaccharide, Grosvenorine, alkaloid and triterpenoid saponin of Siraitia grosvenorii flowers can be obtained at the same time, and efficient comprehensive separation of Siraitia grosvenorii flowers is achieved.

A low-sugar milk tea and a preparation method therefor. The low-sugar milk tea comprises, in parts by weight: 8-15 parts of tea, 8-15 parts of siraitia grosvenorii leaves, 15-20 parts of skim milk powder, 6-10 parts of a sugar substitute, 0.8-1.2 parts of honey, 0.8-1.2 parts of an ethyl maltol dilute solution, 1-3 parts of guar gum, 1-3 parts of an siraitia grosvenorii leaf extract, and 200-400 parts of deionized water, wherein the sugar substitute is prepared from mogroside and erythritol. The low-sugar milk tea prepared by the method not only has high stability, but also tastes good with little bitterness.
Rubus suavissimus S. Lee, extracting with water as a solvent, removing phenolic hydroxyl-containing components, concentrating, purifying, and water-phase crystallization to obtain a sweetening composition. The sweetening composition is white in color, with unobvious bitterness astringent taste. The sweetening composition contains 50% to 99% of Rubusoside based on a dry weight, and has an absorbance of less than 0.4 at a wavelength of 270 to 370 nm after being dissolved and prepared into an aqueous solution (with a solid content of 1%, w/w). By removing bitter glycosides and phenolic hydroxyl-containing components, this application makes the flavor of the sweetening composition better. In the preparation process of the sweetening composition of the this application, only purified water is used and no organic solvents are used.
