Abstract

The invention discloses a method for extracting tabersonine from voacanga seeds. The method comprises the steps: 1, utilizing 50% to 95% ethyl alcohol to ultrasonically extract 3 times to obtain ethanol extract, wherein once extraction is performed for 0.5 to 1 hour; 2, utilizing an organic solvent to extract the ethanol extract 3 to 5 times to obtain organic extractant, wherein once extraction is performed for 3 to 5 hours; 3, utilizing HPD-100 macroporous resin to elute the organic extractant to obtain ethanol eluate; 4, adding acid into the ethanol eluate to extract the ethanol eluate to obtain acid extractant; 5, adding alkali liquor into the acid extractant to adjust the pH value to the alkaline degree and then adding chloroform to extract to obtain tabersonine. The method is simple and low in cost and can effectively improve the extraction purity and yield of the tabersonine.

Description

technical field [0001] The invention belongs to the technical field of extracting taborin, and in particular relates to a method for extracting taborin from potato fruit. Background technique [0002] African potato fruit (Voacanga africana Stapf) is an apocynaceae tree plant, also known as African Vocan tree, its bark is light gray-brown, its branches have lenticels, and its petiole is short or absent; its leaves are obovate oblong or Obovate-elliptic, apex obtuse or acute, both surfaces glabrous or pubescent on the back. African potato is mainly distributed in Africa, and has been successfully introduced and domesticated in South China Botanical Garden, Hainan Tropical Economic Botanical Garden and Xishuangbanna Tropical Botanical Garden in China. [0003] African potato fruit contains alkaloids, flavonoids, anthraquinones, cardiac glycosides, saponins, starch, tannins and other substances, so it has antibacterial activity, antioxidant and anti-inflammatory, anti-ulcer, h...
