Embodiment 1

[0033]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;

[0034] 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;

[0035] 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 bottles -109 bottles), HY-10 (110-127 bottles);

[0036] 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 s...

Abstract

The invention provides alpha/beta-unsaturated ketone and application thereof. The alpha/beta-unsaturated ketone is a compound obtained by recovering useful substances from a waste material produced by extracting aromas from natural plants. The compound is 1,4-bi(4-methoxyphenyl)-3-butene-2-ketone. The industrial waste material is further extracted and utilized, and useful substances alpha/beta-unsaturated ketone are separated out and are used as cigarette aroma-improving additives or antibacterial medicine or antihistamine medicine.

Description
