Preparation method of anti-aging cell telomerase active agent

The invention relates to a process of a preparation method of an anti-aging cell telomerase active agent. The preparation method comprises the following steps: (1) taking 500g of astragalus membranaceus fine powder; (2) putting the astragalus membranaceus fine powder into an HWC-3 microwave extraction equipment instrument, performing microwave heating, performing extraction for three times by using an alcohol and water extraction method, controlling the heating power of the microwave extraction equipment to be 500w-1000w, controlling the temperature to be 70-75 DEG C / C, performing alcohol extraction twice, adding ethanol which is 5 times of the mass of 70-90% of the micro powder for the first time, performing reaction extraction for 20-30 minutes, adding 75-95% ethanol which is 5 times of the mass of the micro powder for the second time, and (3) concentrating the secondary ethanol extracting solution, removing ethanol, adding distilled water which is 10 times of the mass of the astragalus membranaceus micro powder for the third time, heating at 70-75 DEG C / C, reacting for 2 hours, standing for 24 hours, recovering the concentrate from the supernate, and carrying out vacuum drying for 48 hours to obtain an astragaloside active matter crystal. The extraction process method shortens the reaction extraction time, the extraction process is energy-saving and efficient, and the utilization rate of effective components is high.

Chemical inducer for radix astragali adventitious root tissue culture and application of chemical inducer in radix astragali adventitious root culture

InactiveCN114711142AEasy to synthesizePromotes synthesis and accumulationHorticulture methodsPlant tissue cultureBiotechnologyRoot growth
The invention belongs to the technical field of chemical induction of traditional Chinese medicine radix astragali adventitious roots, and provides a chemical inducer for radix astragali adventitious root tissue culture and application of the chemical inducer in radix astragali adventitious root culture in order to solve the problems of green and sustainable development of radix astragali resources at present. Cis-3-hexenal is dissolved in water to prepare a mother solution with the concentration of 200 mmol/L, and the mother solution is stored at the temperature of 4 DEG C for standby application after being filtered and sterilized by a sterile filter membrane. The growth of the radix astragali adventitious roots and the synthesis and accumulation of triterpenes and isoflavone active ingredients are promoted in a dose-dependent manner, so that the browning of radix astragali adventitious root culture is inhibited; and synthesis and accumulation of astragaloside I, isoastragaloside I, astragaloside II, astragaloside III, cycloastragaloside II, liquiritin, formononin, calycosin, glucoside of calycosin and the like in the roots are promoted. The additive is expected to be developed into a green additive which is applied to an astragalus mongholicus adventitious root tissue culture system to improve the yield of root culture and the content of active substances.
