摘要

利用高效液相色谱法(highperformance liquid chromatography,HPLC)和酶标仪等测定了祁连山区不同海拔高度下祁连圆柏(Sabina przewalskii)和青海云杉(Picea crassifolia)叶片中色素含量、花青苷合成酶苯丙氨酸解氨酶(phenylalanine ammonialyase,PAL)和类黄酮糖基转移酶(UDP glucose-flavonoid3-O-glucosyl-transferase,UFGT)活性。结果表明:两树种花青苷(anthocyanin,Acy)含量除了在海拔高度3100-3200m有所升高外,总体上随海拔高度上升...
