Embodiment 1
[0047] The yellow fruit eggplant was collected from the village and roadside of Kafang Town, Gejiu City, Honghe Prefecture, Yunnan Province, and dried in the sun until dry, then dried in an oven at 60°C to constant weight, crushed and sieved (the mesh number of the sieve was 120), and then sieved As a sample of yellow fruit eggplant, it was stored in a sealed bag and placed in a dark and dry environment for later use.
[0048] The yellow fruit eggplant sample was mixed with ethanol aqueous solution with a volume fraction of 40% according to the ratio of solid to liquid: 1g:70mL, and extracted for 40min at a temperature of 50°C, an ultrasonic power of 400kW, and an ultrasonic frequency of 100kHz, and the resulting system The system is filtered, and the obtained filtrate is the extract of yellow fruit eggplant.
Embodiment 2～22
[0050] According to the method of Example 1, the yellow fruit eggplant was extracted to obtain the yellow fruit eggplant extract; the specific operating parameters are listed in Table 1.
[0051] Operating parameters and total flavonoid extraction rate in the extraction process in table 1 embodiment 1~22
[0052]
[0053]
[0054] 1. Identify the types of total flavonoids in the extracts of yellow fruit eggplants prepared in Examples 1 to 22, wherein the total flavonoids have many color reactions, mainly utilizing the properties of the phenolic hydroxyl group and the gamma-pyrone ring in the molecule to develop color , the type and structure of the total flavonoids can be preliminarily speculated through the color reaction. In this experiment, the yellow fruit eggplant extract was used as the sample solution, and the total flavonoids in it were qualitatively identified through the color reaction by sodium hydroxide method, concentrated ammonia method, ferric chloride met...

Abstract
The invention relates to the technical field of plant effective ingredient extraction, in particular to a solarium xanthocarpum extract and an extraction method and application thereof. The method provided by the invention comprises the following steps: extracting solarium xanthocarpum by using an ethanol aqueous solution under the ultrasonic condition to obtain the solarium xanthocarpum extract.By adopting an ultrasonic auxiliary extraction method to extract the solarium xanthocarpum, the extraction time can be effectively shortened, and the extraction rate of effective ingredients and the utilization rate of raw materials in the solarium xanthocarpum are facilitated. Results of embodiments show that the method provided by the invention is used for extracting the solarium xanthocarpum, the extraction rate of total flavone in the obtained solarium xanthocarpum extract reaches 4.27%, and the solarium xanthocarpum extract has stronger scavenging capacity on .OH and DPPH., and also has stronger total antioxidant capacity, so that the solarium xanthocarpum extract extracted by the extraction method provided by the invention has stronger in-vitro antioxidant activity. The solarium xanthocarpum extract can be used as a potential natural antioxidant for development and utilization.
Description
technical field [0001] The invention relates to the technical field of extraction of effective plant components, in particular to a yellow fruit solanum extract and its extraction method and application. Background technique [0002] Yellow fruit eggplant (Solanum xanthocarpum Schrad.&H.Wendl.) belongs to Solanaceae, Solanaceae plant, is a perennial wild plant, aliased as yellow water eggplant, big bitter fruit, wild eggplant fruit, momoziyang, thorny fruit, yellow fruit coral , Spurs, toothache fruit, etc. Huangguosha is a thorny lying herb, 0.5-0.7m high, and the stems and leaves are covered with hard thorns or star-shaped hairs 0.5-2cm long; single leaves are alternate, oval or ovate, 4-7cm long, 2.5-2.5cm wide 4cm, apex pointed or blunt, margin deeply wavy or deeply lobed; flowers 2-5 in cymes and lateral; calyx 5-lobed, with small spines; corolla campanulate, 5-lobed, blue-purple, with hairs outside. [0003] Yellow fruit eggplant is mainly distributed in Fujian, Taiw...
