Background: Belonging to the Boraginacae family, Ehretia asperula Zoll. et Mor., called “Xa den”, is a precious medicinal plant also known as the “cancer tree” by the Muong ethnic group in Hoa Binh Province, Vietnam. Xa den has been demonstrated to inhibit the development of malignant tumors, reduce oxidation and enhance the human immune system. This research focused on examining friable callus induction from young stems of Ehretia asperula Zoll. et Mor. Methods: Samples of Xa den were less than two years old. Young stems with 2 to 6 leaves served as explants for callus induction. Explants placed on autoclaved B5 nutrients incubated at 25oC, in the dark. The testing factors were concentrations of 2,4-Dichlorophenoxyacetic acid (2,4-D) and Benzyl adenine (BA), types and concentrations of sugars.Result: Friable callus was induced on B5 medium with 0.4 mg/L of 2,4-D, 0.1 mg/L of BA and 30 g/L of glucose at the highest rate (100%). Additionally, callus grew best after 5 weeks of culture weighing 0.194 g. Friable callus was used as material for cell suspension cultures. After two weeks, the Xa den cell suspension cultures contained single cells and small cell clumps. The liquid medium had changed from dark yellow to light brown.

2,4 Dichlorophenoxyacetic Acid

Cotyledon cell suspension cultures of bush bean required 2, 4-dichlorophenoxyacetic acid (2,4-D) for growth. Kinetin was not essential but was required for optimum growth. Both of the regulators were required for optimum production of extracellular polysaccharide (EP).The two regulators had different effects upon the production of three polysaccharide fractions (two pectins and a neutral polysaccharide) isolated from the EP at various stages of the culture cycle.The neutral sugar composition of the pectin fractions from all treatments, including regulator treatments, showed considerable fluctuation during the culture cycle and could be changed markedly by regulator treatments. Changes in composition of the neutral polysaccharide were slight. As a consequence of these results it is now possible to obtain cells differing in the nature of the systems synthesizing, or controlling the synthesis of, the polysaccharides.
