Embodiment 1

[0039] Embodiment 1: the method for the composition that extracts from the Spring Orchid, the method is carried out as follows:

[0040] (1) Leaching and filtering: the fresh flowers of Chunlan are placed in petroleum ether with a boiling point of 60-90°C for 24-48 hours, wherein the ratio of fresh flowers of Chunlan to petroleum ether is 1kg: 3L, and then the leaching solution is filtered Obtain the filtrate and flower residue for the first time;

[0041] (2) Reflux leaching and filtering: place flower residues in petroleum ether with a boiling point of 60-90°C, wherein the ratio of flower residues to petroleum ether is 1kg:2L, and reflux for leaching at below 70°C for 4-5 hours , after the leaching solution is completely cooled, filter the leaching solution to obtain the second filtrate and residue;

[0042] (3) Combining and separating: put the above-mentioned first filtrate and second filtrate into a concentrator, concentrate the combined liquid below 35°C and a pressure ...

Abstract

This invention discloses an aroma-producing compound from Cymbidium goeringii and the extraction method thereof. The compound comprises octadecatrienoic aldehyde,nerolidol,dibutylphthalate,heptacosane,pentadecanoic acid,pentadecanoic acid,hexadecanoic acid(palmic acid),oleic acid,linolic acid and cyclohexadecane. The aroma-producing compound is extracted from the flowers of Cymbidium goeringii by the following steps: leaching and filtering, reflux leaching, filtering, combined seperation, volatilized speration, concentration and drying. The main discovery is the octadecatrienoic aldehyde, a critical aroma-producing substance. Besides, the extraction rate of the aroma-producing substances is pretty high, with the content upto 30% by using octadecatrienoic aldehyde and nerolidol as the major aroma-producing product. The components of this invention has satisfied the basic requirements as natural flavoring, and can be used in flavoring agents, perfume, scent emitting objects and bath articles, allowing this natural perfume for industrial application.

Description

technical field [0001] The invention relates to a composition extracted from plants and an extraction method thereof, in particular to an aroma composition extracted from spring orchids and an extraction method thereof.
