Embodiment 1

[0035] Example 1. A method for jointly extracting mallow flavonoids and mallow saponins from seaside mallow, the steps are as follows:

[0036] 1. Collect fresh tubers of seaside mallow, wash, dry and crush. Take 50 grams of dry powder and add 750ml of distilled water in a ratio of 1:15, stir well, and use an ultrasonic instrument for ultrasonic extraction. Ultrasonic conditions: temperature 60°C, power 200W, time 1 hour. After sonication, filter with two layers of gauze. The filtrate was stored, and the filter residue was repeated once again under the above conditions. The two filtrates were combined to obtain 950ml of filtrate, which was evaporated under reduced pressure to obtain 350ml of concentrated solution. Add 910ml of 95% ethanol to make the final concentration 70%. After stirring several times, let it stand for 10 hours, siphon the supernatant, concentrate the supernatant (70% ethanol extract) under reduced pressure to remove ethanol, and obtain 165ml of mallow f...

Abstract

The invention discloses a method for combined extraction of mallow flavones and mallow saponins in seashore mallow, which is characterized by comprising the following steps of: taking the root tuber of fresh seashore mallow, and obtaining dry powder; carrying out ultrasonic treatment; extracting with 70% ethanol; removing the ethanol, and concentrating to obtain crude extracts of flavones and saponins; separating with macroporous resin; washing with water; eluting with 40% ethanol to obtain an eluent containing mallow flavones; then, eluting with 80% ethanol to obtain an eluent containing mallow saponins; and respectively concentrating and drying the two eluents. The mallow flavones and mallow saponins prepared by the method disclosed by the invention can be used for preparing health foods for preventing tumors or medicaments for treating tumors, and can be respectively or jointly prepared into powder, tablets, oral solutions, capsules and other foods or medicaments.

Description

technical field [0001] The invention belongs to the technical field of biochemical separation, in particular to a method for jointly extracting mallow flavonoids and mallow saponins from seashore mallow, and also relates to the use of the mallow flavonoids and mallow saponins extracted by the aforementioned method. Background technique [0002] Seashore mallow (kostelezkya virginica) is a perennial halophyte of Malvaceae, which is naturally distributed in the salt marsh coastal zone of the eastern coast of the United States. It was introduced to China by Nanjing University in 1992. It has been reported in the literature that the flowers, leaves and roots of seaside mallow are edible. In particular, the roots can be eaten raw, cooked and fried, and can be used as tea drinks, and can be dried and crushed to be used as raw materials for candy and chewing gum to increase the viscosity of the gum. The root extract can be concentrated to egg white for use instead of egg white. ...
