Embodiment 1

[0034] Example 1: Isolation of Oxycyclopentadecane-2-one from Dictyophora

[0035] The implementation steps of this embodiment are as follows:

[0036] A. Pretreatment

[0037] Drying Dictyophora until the water content is 65108% based on the total weight of the dried Dictyophora, and then crushing it into 50406050 mesh to obtain a dry Dictyophora powder;

[0038] B. Extraction

[0039] Add the dry Dictyophora powder that step A obtains in the first round bottom flask, then add water, the weight ratio of described dry Dictyophora powder and water is 2:50;

[0040] Simultaneously, organic solvent is added in the second round bottom flask, and described organic solvent is ethanol organic solvent;

[0041] The volume ratio of the organic solvent to the water is 2:10;

[0042] Then, connect the above two round bottom flasks to the distillation extraction device at the same time, put the first round bottom flask into an oil bath to heat, and control its temperature at 138°C; pu...

Abstract

The invention relates to a method for separating oxacyclopentadecane-2-ketone from bamboo fungus. The method comprises the following steps of: pre-treating the bamboo fungus, extracting the pre-treated bamboo fungus, drying and concentrating the extract liquor, chromatography-separating, identifying and the like. The method has the positive effect of promoting new product development of food essences and facilitating enriching special flavors of the food.

Description

【Technical field】 [0001] The invention belongs to the technical field of spice processing. More specifically, the present invention relates to a method for isolating oxacyclopentadecan-2-one from Dictyophora. 【Background technique】 [0002] Dictyophora duplicata belongs to the fungi of the phylum Fungi, Basidiomycotina, Epimycetes, Phallogramles, Dictyophora duplicata, and the genus Dictyophora. Dictyophora is a precious edible and medicinal fungus. Because it can only be obtained in the wild environment, and the yield is small, it needs special preservation. It is also recognized by the international community as "very good food" because it is rich in protein and other nutrients. It has the reputation of "modern health food", "the pinnacle of human plant food" and so on. Chinese bamboo fungus has a long history of eating, and it is also the first country to realize cultivation. The more famous dish is "bamboo fungus goose". At present, the research on Dictyophora mainly ...
