Abstract

The invention discloses a preparation and cultivation method of hairy roots of tongkat ali and belongs to the biological cell engineering technology. The preparation and cultivation method includes: tender stems of tongkat ali are used as explants which subjected to dedifferentiation to obtain fresh callus of tongkat ali, the callus and Agrobacterium rhizogenes containing Ri (root-inducing) plasmid are co-cultured, co-cultured bacteria liquid is transferred to an inductive medium for induced culture after excess bacteria liquid is absorbed with aseptic paper, fairy roots of tongkat ali grow at the callus of tongkat ali; and the explants with hairy roots are laced in an amplification medium for extended culture of the hairy roots after biostatistics culture. The tongkat ali hairy root culture system is established by the biological cell engineering technology and used to prepare the hairy roots of tongkat ali, standard production of tongkat ali is realized, wild resources are replaced, increasing market demands on tongkat ali are eased, and the problem that tongkat ali relies on import is solved. The preparation and cultivation method is important to industrial and commercial development of hairy roots of medicinal plants.

Description

technical field [0001] The invention relates to a method for preparing and cultivating a hairy root system of a plant, in particular to a method for preparing and cultivating a plant hairy root system, which belongs to biological cell engineering technology. Background technique [0002] The scientific name of Tongkat Ali is Eurycoma longifolia Jack, which belongs to Simaroubaceae. Dongge Ali is a slow-growing tropical rainforest shrub plant, mainly distributed in Southeast Asian countries and regions such as Malaysia, the Philippines, Indonesia and Thailand. Its roots are used as medicine, and are often used to treat diseases such as malaria, dysentery, oral ulcers, scarlet fever, headaches, etc. It also has the effect of enhancing male sexual function, and is called "Malaysian ginseng". Recent studies have shown that quassinoids extracted from this plant species also have good anti-tumor and anti-HIV effects. Dongge Ali is a dioecious plant. Because Dongge Ali is a worl...
