Embodiment 1

[0040] A process for extracting trilobatin from Fructus Alba lanceolata, comprising the following steps:

[0041] S1: Raw material crushing: select the tender leaves of Mujiraecho produced in April, coarsely pulverize them with a pulverizer to obtain Mujiraeba granules, and sieve the obtained Mujiraeba granules through a 10-mesh sieve to obtain Mujiraecho coarse powder;

[0042] S2: Heating and separating: put the cassava powder obtained in step S1 into the heating reflux separator, then add pure water to the cassava powder in the heating reflux separator, heat the cassava powder in the reflux separator and The weight ratio of pure water is 1:6, and the heating temperature is 80°C. When the amount of phyllophyll leaf powder added at one time to the heating reflux separator is 1kg, the heating time is 10min. When the amount of the cassava coarse powder exceeds 2kg, the heating time is increased by 5min / 1kg on the basis of 10 minutes, and the cassava mixture A is obtained after ...

Embodiment 2

[0052] A process for extracting trilobatin from Fructus Alba lanceolata, comprising the following steps:

[0053] S1: Grinding of raw materials: select the young leaves of Mujiraecho produced in June, and coarsely pulverize them with a pulverizer to obtain Mujiraeba granules, and sieve the obtained Mujiraeba granules through a 10-mesh sieve to obtain Mujiraecho coarse powder;

[0054] S2: Heating separation: put the cayenne leaf powder obtained in step S1 into a heating reflux separator, the heating reflux separator used is the same as the heating reflux separator used in Example 1, and then the wood in the heating reflux separator Add pure water to the coarse powder of Ginger Yeke, and the weight ratio of the coarse powder of Ginger Yeke to the purified water in the heating reflux separator is 1:11, and the heating temperature is 90°C. When the weight is 1.5kg, the heating time is 10min. When the amount of cassia japonica coarse powder added at one time in the heating reflux ...

Embodiment 3

[0063] A process for extracting trilobatin from Fructus Alba lanceolata, comprising the following steps:

[0064] S1: Raw material crushing: select the tender leaf products of Mujiraecho produced in November, coarsely pulverize through a pulverizer to obtain Mujiraja granules, and sieve the obtained Mujiraeba granules through a 10-mesh sieve to obtain Mujiraegae coarse powder;

[0065]S2: Heating separation: put the cayenne leaf powder obtained in step S1 into a heating reflux separator, the heating reflux separator used is the same as the heating reflux separator used in Example 1, and then the wood in the heating reflux separator Add pure water to the coarse powder of Jiangyeke, heat the weight ratio of the coarse powder of Jiangyeke to the purified water in the reflux separator to 1:20, and the heating temperature is 100°C. When it is 2kg, the heating time is 10min, and when the amount of the coarse powder of Mujiangyeke added at one time in the heating reflux separator exc...

Abstract

The invention discloses a process for extracting trilobatin from lithocarpus litseifolius and belongs to the technical field of monomer separation. The process comprises the following steps: S1, grinding raw materials; S2, heating and separating; S3, performing vacuum concentration; S4, extracting and precipitating; and S5, crystallizing. The specific steps are as follows: grinding the selected lithocarpus litseifolius leaves, extracting crude powder of the ground lithocarpus litseifolius with water, heating, refluxing and separating, filtering the separating medium, separating the filter residues and filtrate, extracting the filtrate for multiple times, mixing the filtrate and performing vacuum concentration, extracting the solution after concentration, performing thermal saturation crystallization after extraction, and finally obtaining the trilobatin crystal by virtue of multiple crystallizations. The purity of the obtained trilobatin crystal is more than 98%. The trilobatin extracted by the process disclosed by the invention is high in purity and excellent in color, and the process is simple and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of monomer separation, in particular to a process for extracting trilobatin from Akeba officinalis. Background technique [0002] Sweeteners refer to food additives that impart sweetness to food or feed, improve food quality, and meet people's needs for food. Lithocarpus pachyphyllus (Kurz) Rehd., also known as Lithocarpus pachyphyllus (Kurz) Rehd., is also known as Lithocarpus pachyphyllus (Kurz) Rehd. The plant of the genus Shike is a precious forest medicinal tree species lurking deep in the mountains. It has three functions of tea, sugar and medicine. Its tender leaves (or tender leaf products) have a high sweetness after soaking, so it is called "sweet tea". The chemical components of Duosuike sweet tea are mainly flavonoids and triterpenoids, among which trilobatin in young leaves is the main sweet component of Duosuike sweet tea, and its content reaches more than 85% of the total flavonoids. Becaus...
