Embodiment 1

[0029] Dry the sycamore flower in the shade, crush it, and pass through a 40-mesh sieve to obtain the sycamore flower powder; put 1000g of the sycamore flower powder into the extraction kettle, set the extraction pressure to 25MPa, the extraction temperature to 40°C, the separation kettle I pressure to 10MPa, and the temperature to 30°C. Kettle II pressure 5MPa, temperature 20°C, CO 2 The flow rate is 20kg / h; after 2h of extraction, CO is removed under reduced pressure 2 After collecting the extract, 14.34mL of parasol flower volatile oil can be obtained.

Embodiment 2

[0031] Dry the sycamore flower in the shade, crush it, and pass through a 40-mesh sieve to obtain the sycamore flower powder; put 1000g of the sycamore flower powder into the extraction kettle, set the extraction pressure to 30MPa, the extraction temperature to 45°C, the separation kettle I pressure to 15MPa, and the temperature to 40°C. Kettle II pressure 8MPa, temperature 25°C, CO 2 The flow rate is 30kg / h; after 3h of extraction, CO is removed under reduced pressure 2 After collecting the extract, 16.11 mL of parasol flower volatile oil can be obtained.

Embodiment 3

[0033] Dry the sycamore flower in the shade, crush it, and pass through a 40-mesh sieve to obtain the sycamore flower powder; put 1000g of the sycamore flower powder into the extraction kettle, set the extraction pressure to 35MPa, the extraction temperature to 50°C, the separation kettle I pressure to 12MPa, and the temperature to 35°C. Kettle II pressure 10MPa, temperature 30°C, CO 2 The flow rate is 25kg / h; after 3h of extraction, CO is removed under reduced pressure 2 After collecting the extract, 15.64mL of sycamore flower volatile oil can be obtained.

Abstract

The invention relates to a preparation method of phoenix tree flower essential oil and an anti-tumor application thereof. The preparation method comprises the following steps: drying phoenix tree flowers in the shade, crushing and screening the phoenix tree flowers by a 20-mesh sieve, putting into an extraction cylinder for cycle extraction, and collecting an extractant after vacuum analysis with a separation kettle, so as to obtain the phoenix tree flower essential oil. The method disclosed by the invention is less in elapsed time and high in yield, and more ingredients are extracted, oxidization and pyrolyzation of the essential oil are prevented, and the quality of the essential oil is improved. The essential oil obtained by the method disclosed by the invention has relatively good anti-tumor activity, and a new way is opened up for development and application of a new generation of anti-tumor drugs with a natural source.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a preparation method and application of parasol flower volatile oil. Background technique [0002] Wutong, also known as Qingtong, is a deciduous tree belonging to the Wutong family. Its roots, bark, leaves and flowers all have certain medicinal value. Indus flower, sweet in nature, flat in taste and non-toxic, has the functions of clearing away heat and detoxification, expelling wind and dampness, diuresis and swelling in the three meridians of human liver, kidney and lung. Indications of edema, bald sores, burns and other diseases. At present, there are domestic studies on the pharmacological effects of sycamore seeds, leaves and pollen, but there are few reports on the extraction method of volatile oil from sycamore flowers. Studies have shown that the volatile oil of sycamore flower has many chemical components, including a large amount of alkanes, hematoporph...
