摘要:目的:为扩大和提高甘肃道地药材秦艽资源的利用效率。方法:以秦艽种子的萌发所获得的幼芽作为外植体,诱导形成愈伤组织;筛选诱导愈伤组织产生的不同培养基和培养条件,并继代培养;应用HPLC法测定龙胆苦苷的含量。结果:秦艽愈伤组织生长的最佳培养基为MS+2,4-D(1.0 mg/L)+6-BA(0.5 mg/L),最佳继代培养基为MS+2,4-D(1.0 mg/L)+6-BA(0.5 mg/L)+NAA(0.5 mg/L),最佳继代时间为30 d。龙胆苦苷积累量在指数生长后期(28~30 d)达最高,为0.78 mg/g DW。结论:筛选出了适宜的秦艽愈伤组织培养方法。秦艽愈伤组织在固体培养基上的生长曲线呈"S"型,且愈伤组织中龙胆苦苷的积累量随愈伤组织增殖而不断增加。
Objective:To explore and improve the utilization efficiency of Gentiana macrophylla resources. Methods:The germina-tion of Gentiona rnacrophylla seeds were used as explants to induce calluses; Cultured on various culture media and condition for callus induction and subculture by test; The content of gentiopieroside in callus was determined by HPLC. Results :The optimum medium for callus was MS + 2,4-D ( 1.0 mg/L) + 6-BA(O. 5 rag/L), and MS + 2,4-D( 1.0 mg/L) + 6-BA(O. 5 mg/L) + NAA(0. 5 mg/L) was the optimum for subculture,the optimum time of subculture was 30 d; The accumulated gentiopicroside reached the highest level with O. 78 mg/g DW when entered 28 - 30 d. Conclusion : The optimized culture method of callus of Gentiana. macrophylla is obtained ; The growth curve of callus of Gentiona macrophylla turns on "S" appearance and the accumulated gentiopieroside increases along with the callus appreciation.
