Embodiment 1

[0048] Take 100 g of star anise residue, add 300 ml of ethyl acetate, stir at room temperature for 2 hours, filter off the insoluble matter to obtain the filtrate, weigh 100 g of column chromatography silica gel, add to the filtrate, and mix the sample;

[0049] Weigh 820g column chromatography silica gel column, and use pure cyclohexane, cyclohexane: ethyl acetate = 50:1, 10:1, 5:1, 1:1 mixed solvent gradient elution, each bottle flow Tap liquid 250ml;

[0050] Each fraction was detected by thin-layer chromatography, and the combined bottle numbers were as follows: HY-1 (1-26 bottles), HY-2 (27-32 bottles), HY-3 (33-37 bottles), HY-4 ( 38-50 bottles), HY-5 (51-77 bottles), HY-6 (78-81 bottles), HY-7 (82-88 bottles), HY-8 (89-99 bottles), HY-9 (100 -109 bottles), HY-10 (110-127 bottles);

[0051] Distill HY-7 to remove the solvent under reduced pressure to obtain 5.1g of viscous material, mix the sample with 10g of silica gel for column chromatography, weigh 120g of silica ...

Abstract

The invention provides a method and use for recovering useful substances in a residual liquid at the bottom of a rectifying still for extracting spices from a natural plant anise, particularly an extraction method of 4-hydroxyl-3-(1, 2-dimethyl-2-propylene) benzaldehyde and use thereof. The extraction method of 4-hydroxyl-3-(1, 2-dimethyl-2-propylene) benzaldehyde comprises the following step: dissolving an illicium verum rectifying still residual liquid; and carrying out silica gel column chromatography twice, primary gel column chromatography and ethyl acetate recrystalization to obtain 4-hydroxyl-3-(1, 2-dimethyl-2-propylene) benzaldehyde. According to the invention, industrial waste materials are further extracted and utilized, and useful substances alpha, beta-unsaturated ketones are separated for oxidant resistance, blood pressure prevention and blood sugar prevention and can be further applied to producing a fragrance-promoting additive for cigarettes.

Description

technical field [0001] The invention relates to the technical field of extracting spices from natural plants, in particular to a method and application for recovering useful substances from the distillation bottom raffinate of spices extracted from natural plant star anise. Background technique [0002] Star anise is a Magnoliaceae plant, and its Latin name (IlliciumverumHooK.f.) is an evergreen tree. It is a special aromatic plant in my country, mainly distributed in Guangxi, Guangdong, Guizhou, Yunnan and other provinces. Guangxi is the main production area of ​​star anise in my country, and its output accounts for 85% of the country and 70% of the world. The star anise tree has become one of the important economic tree species in the local mountainous areas. Star anise and star anise oil are excellent food seasonings that people like to use. Star anise oil has a spicy aroma of star anise, also known as star anise. In addition to being used as a seasoning spice, it is wide...
