肉苁蓉组织培养研究进展及应用前景

肉苁蓉由于采挖过度而濒临灭绝,组织培养是合理利用肉苁蓉,防止其资源枯竭的有效方法。组织培养研究较多的是荒漠肉苁蓉和盐生肉苁蓉,分别对这两种肉苁蓉愈伤组织的诱导、培养基的优化和药用成分的诱导条件等方面的研究进行综述,介绍了应用组织培养生产肉苁蓉药用成分的经济价值和生态效益,以及利用组织培养进行肉苁蓉快速繁殖的实践意义,浅析了肉苁蓉大规模细胞培养的产业化前景。

Research progress and application prospect on tissue culture of Herba Cistanche

Objective To study the sample quality of 'whitish' Radix Salvia Miltiorrhiza(the root of a grown-environmental-influenced variant sample of Salvia miltiorrhiza,which cortex and transection is white) grown in Luanchuan Region of Henan Province and normal Radix Salvia Miltiorrhiza by the means of TLC and HPLC chromatographic fingerprints;hence to compare the difference of their constituents.Methods TLC Chromatographic condition: Precoated silica gel F_(254) plate;hydrophilic and lipophilic constituents were developed and derivatizated with different solvent systems and visualization reagents,respectively.HPLC Chromatographic condition: Zorbax SB C_(18) column;hydrophilic and lipophilic constituents were gradient eluted,respectively.Results The 'whitish' Radix Salvia Miltiorrhiza contains lower content of lipophilic compounds,the main diterpene quinones was only trace amount,while the content of hydrophilic constituents was relatively higher.Conclusion The 'whitish' phenomenon suggests that the 'micro'-environmental condition can probably influence negatively the bio-synthesis of diterpene-quinones.The factors of influence still need further study.Such phenomenon would be worth concerning seriously for GAP administration.
