Conclusion: the method is simple, accurate, reproducible and suitable for the determination of polysaccharide in cultivating liquid of photosynthetic bacteria transforming ramulus viscid.
结论:所用方法操作简便,重复性好,适用于光合细菌转化槲寄生培养液中多糖的含量测定。
Aim: To observe the antagonistic effect of different solution extracts of ramulus viscin on platelet-activating factor (PAF).
目的:观察中药槲寄生不同溶剂提取物对血小板活化因子(PAF)的拮抗作用。
The results of experiment showed that the rooting capability of young ramulus cuttings with the xyloid basis and old cuttings with the flower buds removed was stronger than that of the control.
结果表明,保留木质基部的嫩枝插穗和摘去花苞的硬枝插穗其生根能力显着高于对照。
