Abstract

The invention discloses a method for culturing adventitious roots of oplopanax elatus Nakai by utilizing a bioreactor. The method comprises the steps of: injecting 4L of an MS culture medium in the 5L airlift bioreactor and adding 3-4mg/L of IBA (Iso Butyl Alcohol) and 40-50g/L of white sugar, wherein the pH is 5.8; injecting air at 75-100mL/min; and inoculating 20-40g of adventitious root explants, and culturing for 40-50 days in dark, so as to obtain a large number of adventitious roots of the oplopanax elatus Nakai. The total phenols content in each obtained adventitious root of the oplopanax elatus Nakai is higher than that in the root and the stem of cultivated oplopanax elatus Nakai with two or five growth years and the polysaccharide content in the adventitious roots is approximate to that in the root of the cultivated oplopanax elatus Nakai with the two growth years. The method is capable of accelerating the multiplication rate, so as to obtain a large number of explants within a short period. The bioreactor is used for cultivation, the cost of the culture medium can be reduced, the labor intensity and the production cost can be lowered, the problems that currently the wild oplopanax elatus Nakai plants are endangered and the artificial cultivation difficulty o the oplopanax elatus Nakai plants is high are solved and a new approach is provided for the commercialized production.

Description

Technical field [0001] The present invention involves the field of biotechnology, and specifically involves a method that uses biological reactors to cultivate northeast assassin. Background technique [0002] Northeast Assassin ( Oplopanax ellaatus NAKAI), also known as thorns, has the genus of Wujiake, and has perennial deciduous shrubs. It is a medicinal plant unique to Changbai Mountain in my country.The distribution area of Northeast Assassin is very narrow, mainly distributed in the Governor of Jilin Governor, and Russia and North Korea are also distributed.In the past 10 years, natural resources have been severely damaged due to a large number of excavations.At present, the natural Northeast Assassin's ginseng resources in Changbai Mountain have been endangered and are listed as a national second -category protected plant. [0003] The root and stems of the Northeast Assassin containing a variety of saponin, flavonoids, volatile oils, pyrine, fatty acids, proteins, sugars,...
