specific Embodiment approach 1

[0008] Embodiment 1: This embodiment provides a method for ultrasonic extraction of saponins from leaves of Aralia japonica, which is specifically completed according to the following steps:

[0009] Put the leaves of Aralia japonica into a container, then add an ethanol solution with a mass fraction of 40% to 90%, and extract under the action of ultrasonic waves with a frequency of 40kHz and a power of 250W, the extraction temperature is 40-90°C, and the extraction time is 15-90min , to obtain the extract, the obtained extract is filtered → concentrated and evaporated to dryness → degreasing → extraction → evaporated to dryness to obtain purified saponin;

[0010] The leaves of Aralia japonica described in this embodiment are collected from August 1st to August 20th every year, dried at 40-100°C to constant weight, and then crushed through a 40-mesh sieve.

[0011] The mass ratio of the leaves of Aralia japonica described in this embodiment to the ethanol solution is 1: (10-6...

specific Embodiment approach 2

[0015] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the described Aralia leaves are collected from August 1st to August 20th every year, and dried at 50-80°C until constant Heavy, then crushed through a 40-mesh sieve. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0016] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the leaves of Aralia aralia are collected from August 1st to August 20th every year, and baked at 55-65°C Dry to constant weight, and then crushed through a 40-mesh sieve. Others are the same as in the first or second embodiment.

Abstract

The invention discloses an ultrasonic extraction method for saponin of Aralia elata blade, which relates to an extraction method for the saponin of the Aralia elata blade and aims to solve the problems that low extraction efficiency of saponin in the prior art by adopting the method for extracting the saponin of the Aralia elata blade. The ultrasonic extraction method for the saponin of the Aralia elata blade comprises the following operating steps: putting the Aralia elata blade in a container; then adding an ethanol solution of which the parts by weight is 40-90 percent; carrying out extraction under the action of an ultrasonic wave of which the frequency is 40kHz and the power is 250W at the temperature of 40-90 DEG C for 15-90min to obtain an extracting solution; and filtering, concentrating, evaporating and drying, degreasing, extracting and then evaporating and drying the obtained extracting solution to obtain the purified saponin. The ultrasonic extraction method for the saponin of the Aralia elata blade is mainly used for extracting the saponin from the Aralia elata blade.

Description

technical field [0001] The invention relates to a method for extracting saponins from leaves of Aralia japonica. Background technique [0002] Aralia elata (Miq.) Seem.], also known as Aralia elata (Miq.) Seem., is also known as Aralia elata (Miq.) Seem. Araliaceae (Araliaceae) Aralia plants, perennial deciduous small trees. Its edible organs are tender shoots, which are wild vegetables that people like to eat at home and abroad; studies have shown that the roots, stems, leaves and other organs of Aralia japonica contain a variety of triterpenoid saponins, the main saponin is oleanolic acid, It has the effects of enhancing physical fitness, anti-fatigue, anti-inflammatory, liver protection, lowering blood sugar and blood lipids, anti-cancer, anti-virus, etc., and has significant medicinal value, so it can be used as a raw material for the production of traditional Chinese medicine preparations. [0003] Saponin (saponin) is another name: alkali soap, saponin, saponin or sa...
