Problems solved by technology

For a long time, the extraction of camphor oil has mostly adopted the traditional batch distillation method, which has low oil yield, high energy consumption, long extraction process, and will cause certain environmental pollution and waste of resources.
Therefore, how to effectively solve the problems of long time and low extraction rate of traditional extraction methods has become the difficulty of current research.

Embodiment 1

[0028] Example 1: Weigh 1000g of fresh leaves of Camphor oleifera and 5g of Bacillus strains and mix them, fermented at PH=6 and temperature of 30°C for 48h, and then subjected the mixture obtained after the fermentation to steam distillation for 2h , to obtain 32g of camphor oil. Compared with the existing batch distillation extraction method (general yield is 2%, distillation time generally takes 4h), the yield of camphor oil extracted by the method of this embodiment can be increased by about 60%, and the distillation time can be shortened by 2h.

Embodiment 2

[0029]Embodiment 2: Weigh 1000g of fresh leaves of Camphor oleifera and 7g of lactic acid bacteria strains and mix the two, fermented for 60h at PH=6.5 and temperature of 28°C, then the mixture obtained after the fermentation was subjected to steam distillation for 2h, 30 g of camphor oil was obtained. Compared with the existing batch distillation extraction method (general yield is 2%, distillation time generally takes 4h), the yield of camphor oil extracted by the method of this embodiment can be increased by about 50%, and the distillation time can be shortened by 2h.

Embodiment 3

[0030] Embodiment 3: Weigh 1000g of fresh leaves of Camphor oleifera and 6g of Bacillus megaterium strains and mix the two, fermented for 72h at PH=5.5 and temperature of 32°C, and then the mixture obtained after the fermentation was subjected to steam distillation 2h, 31 g of camphor oil was obtained. Compared with the existing batch distillation extraction method (general yield is 2%, distillation time generally takes 4h), the yield of camphor oil extracted by the method of this embodiment can be increased by about 55%, and the distillation time can be shortened by 2h.

Abstract

The invention relates to a method for extracting cinnamomum longepaniculatum oil. Themethod comprises the following steps of: mixing at least one of a microbial strain and a biological enzyme with cinnamomum longepaniculatum leaves to decompose the cinnamomum longepaniculatum leaves to obtain a decomposed mixture; and carrying out steam distillation on the mixture to extract the cinnamomum longepaniculatum oil in the mixture. According to the method disclosed by the invention, the extraction yield of the cinnamomum longepaniculatum oil can be effectively improved, the time required by subsequent distillation can be shortened, and residues of an organic solvent can be avoided, so that the purity of the cinnamomum longepaniculatum oil is guaranteed.

Description

technical field [0001] The present invention generally relates to the technical field of vegetable oil extraction. More specifically, the present invention relates to a method for extracting camphor oil. Background technique [0002] Oil camphor is a unique tree species in Sichuan, and the aromatic oil extracted from its leaves is a best-selling material in foreign trade and an important raw material for the daily chemical industry. There are more than 100 kinds of components in camphor oil, of which 1,8-cineole accounts for about 60%. This substance has important antibacterial and antiviral effects, especially has a strong preventive effect on coronavirus. For a long time, the traditional batch distillation method has been used for the extraction of camphor oil, which has low oil yield, high energy consumption, long extraction process time, and also causes certain environmental pollution and resource waste. Therefore, how to effectively solve the problems of long time and...
