Embodiment 1

[0015] Example 1. A method for extracting borneol from Ainaxiang, prepared according to the following steps:

[0016] a. Dry the leaves of the new Ainaxiang leaves in the shade at 35°C for 2 hours;

[0017] b. Weigh 5g of Ai Naxiang leaves after drying in the shade, cut it into a small section with a diameter of 2mm, put the cut section into 40ml of ethyl acetate and seal it, and then ultrasonically treat it for 35min to obtain an ultrasonic solution;

[0018] c. Leave the ultrasonic solution for 12 hours to obtain a standing solution;

[0019] d. Suction filtration, drying, washing, and re-drying of the standing liquid to obtain final product.

[0020] The condition of the aforementioned ultrasonic treatment is that the power is 550W and the frequency is 40kHz.

Embodiment 2

[0021] Example 2. A method for extracting borneol from Ainaxiang, prepared according to the following steps:

[0022] a. Shade-drying the leaves of Xinainaxiang at 30°C for 3 hours;

[0023] b. Weigh 6g of Ai Naxiang leaves after drying in the shade, cut it into a small section with a diameter of 1mm, put the cut section into 45ml of ethyl acetate and seal it, and then ultrasonically treat it for 32min to obtain an ultrasonic solution;

[0024] c. Leave the ultrasonic solution for 13 hours to obtain a standing solution;

[0025] d. Suction filtration, drying, washing, and re-drying of the standing liquid to obtain final product.

[0026] The conditions of the aforementioned ultrasonic treatment are that the power is 500W and the frequency is 45kHz.

Embodiment 3

[0027] Example 3. A method for extracting borneol from Ainaxiang, prepared according to the following steps:

[0028] a. Dry the leaves of the new Ainaxiang leaves in the shade at 45° C. for 1 hour;

[0029] b. Weigh 5 g of Ai Naxiang leaves after drying in the shade, cut it into a small section with a diameter of 1 mm, put the cut section into 40 ml of ethyl acetate and seal it, and then ultrasonically treat it for 30 minutes to obtain an ultrasonic solution;

[0030] c. Leave the ultrasonic solution for 14 hours to obtain a standing solution;

[0031] d. Suction filtration, drying, washing, and re-drying of the standing liquid to obtain final product.

[0032] The condition of the aforementioned ultrasonic treatment is that the power is 550W and the frequency is 40kHz.

Abstract

The invention discloses a method of extracting camphol from blumea balsamifera: preparing by the following steps: a.new leaves of blumea balsamifera are shade-dried; b. blumea balsamifera leaves of 3to 8 grams that are shade-dried are weighted and cut into segments of 1 to 3 millimeters in diameter, the cut segments are sealed in ethyl acetate of 25 to 55 milliliter, after that, the ultrasound treatment is carried out for 30 to 35 minutes and the ultrasound solution is obtained; c. the ultrasound solution is fixed for 10 to 15 hours, and the static solution is obtained; d. the static solution is filtrated, dried, rinsed and dried again, then the camphol is gained. The method of extracting camphol from blumea balsamifera has the advantages that the extraction rate and the utilization rate of raw materials are high.

Description

technical field [0001] The invention relates to a method for extracting traditional Chinese medicine, in particular to a method for extracting borneol from Ainaxiang. Background technique [0002] Ainaxiang (scientific name: Blumea balsamifera (L.) DC.), is a perennial herb or subshrub of the genus Ainaxiang in the Asteraceae family. The stem is sturdy, erect, 1-3 meters high; the lower leaves are broadly elliptic or oblong-lanceolate, with stalk, and there are 3-5 pairs of narrow linear appendages on both sides of the stalk; the upper leaves are oblong-lanceolate or ovate lanceolate, sessile or short-stalked, often with 1-3 pairs of narrow linear appendages on both sides of the stalk; inflorescences numerous, involucre bell-shaped, receptacle honeycomb-shaped, 2-3 mm in diameter, glabrous. Flowers yellow, mostly female flowers, corolla thin tubular, hermaphrodite flowers few, corolla tubular; achenes cylindrical, densely pilose. Pappus reddish-brown, rough hairy. The flo...
