固定化介导提高苦味叶下珠中的海冰叶下珠脂素和叶下珠次素的含量(英文)

摘要： Phyllanthus amarus plant is used in the traditional system of medicine as a hepatoprotective drug for which the majorlignans phyllanthin and hypophyllanthin are responsible.So far,no significant work has been done on the culture of this plant.Realizingthe hepatoprotective potential,the present investigation was undertaken.A cost effective process was developed for enhancingphyllanthin and hypophyllanthin utilizing the immobilization technique.HPTLC was used to compare the phyllanthin and hypophyllanthincontents in calcium alginate immobilized cells obtained from fresh grown plants and MS medium was supplemented withdifferent abiotic elicitors,under aseptic conditions for the treatment with chitosan,copper sulphate,phenylalanine and silver nitratesolution to make the whole process commercially viable.It was revealed that silver nitrate and phenylalanine at low concentrationenhances phyllanthin and hypophyllanthin yield as compared to control immobilized cell culture.The study revealed that an increase inthe content of phyllanthin and hypophyllanthin was elicitor concentration dependent and silver nitrate treatment gave a maximum yieldof hepatoprotective bioactives as compared to the other abiotic elicitors used. ... （共6页）
