The results showed that the ultrasonic extraction is a rather ideal method of extracting red P. tha fortuneana pigment. Cyanidin3glucoside can be hydrolysised to aglycon cyanidin under the conditions of 90℃, 9％HCl and 11min.Silica gel thinlayer chromatography with developping agent benzene∶ethyl acetate∶formic acid = 2∶2∶1 is better to separate cyanidin. Cyanidin is stable to heat and light, unstable to Zn2+ and Fe3+ and Cu2+, insensitive to Co2+ and Bi3+, befitting to acidic condition.

结果表明，超声提取法是提取火棘红色素的较理想方法；矢车菊素3葡萄糖苷在90℃和9％盐酸中水解11 min，可以顺利得到其苷元矢车菊素；以苯、乙酸乙酯、甲酸(2∶2∶1)为展开剂的硅胶薄层层析法分离矢车菊素的效果较好；矢车菊素对热和光较稳定，在酸性条件下稳定，对Co2+和Bi3+不敏感，对Zn2+、Fe3+、Cu2+不稳定。

The silk-protein-like polymers could be dissolved in hexafluroisopropanol and strong organic acid (e. g., formic acid, dichloroacetic acid and trifluroacetic acid), while they showed a poor solubility in common solvents.

所合成的模拟聚合物难溶于通常溶剂，但可以溶解在强酸溶剂（甲酸、二氯乙酸及三氟乙酸）和六氟异丙醇中；通过在二氯乙酸中25℃下的特性粘度测定而估算出聚合物的分子量在2～5万之间。
