Abstract

The invention provides an extraction method of Flos chrysanthemi indici volatile oil.The extraction method includes: removing receptacles, sepals and flower stalks of dry Flos chrysanthemi indici; smashing petals of the dry Flos chrysanthemi indici into Flos chrysanthemi indici powder, and repeatedly freezing and thawing for 2-3 times; adding into water of 60-70 DEG C for soaking for 1-2 h, and ultrasonically treating the Flos chrysanthemi indici powder after being soaked and extract; performing distillation extraction on the Flos chrysanthemi indici powder after being ultrasonically treated and the extract at 100-120 DEG C for 3-5 h, and collecting upper-layer oily substance in distillation condensate to obtain Flos chrysanthemi indici volatile oil crude extract; using macroporous resin to adsorb and desorb the Flos chrysanthemi indici volatile oil crude extract to obtain pure Flos chrysanthemi indici volatile oil.No additive or organic solvent is used in the method, so that original fragrance of volatile oil is retained; no organic solvent is left in the Flos chrysanthemi indici volatile oil, so that the extraction method is safer and pollution-free.The extraction method has the advantages that extraction rate is up to 7.5%, extraction time is short, and extracted volatile oil is higher in purity.

Description

technical field [0001] The invention belongs to the technical field of chemical extraction, and in particular relates to a method for extracting volatile oil from wild chrysanthemum flowers. Background technique [0002] Wild chrysanthemum is the dry flower head of Chrysanthemum indi-cum Lamb (Chrysanthemum indi-cum Lamb), also known as malaria grass, bitter barley, mountain chrysanthemum, etc. It has the functions of calming the liver and improving eyesight, clearing away heat and detoxification, stopping bleeding and reducing swelling, etc., and has high medicinal value. The main components of wild chrysanthemum volatile oil (essential oil) are monoterpenes, sesquiterpenes and their oxygen-containing derivatives and aliphatic compounds. and insect repellent, and the unique fragrance of volatile oil is widely favored by the general public, and can be used in industries such as perfume and cosmetics. Therefore, chrysanthemum volatile oil has very broad development prospects...
