A novel catalytic resonance light scattering method for the determination of traces of formaldehyde in blood plasma was developed. It was based on the fact that potassium bromate reacted with pyronine Y to form association nanoparticles which gave stronger resonance light scattering effect, and formaldehyde can catalyze potassium bromate oxidizing pyronine Y resulting in decreasing of the intensity of resonance light scattering in sulfuric acid.

在稀硫酸介质中，溴酸钾与吡啰红Y能聚集成较大粒径的纳米微粒而使共振光散射增强，而甲醛能催化溴酸钾氧化吡啰红Y而导致体系共振光散射减弱，据此建立了一种灵敏、简单、快速测定血浆中痕量甲醛的新方法。

The content of the composition of polysaccharides was determined by anthranone-sulfuric acid method. Result There was no absorption at 240 nm and 260 nm. The IR spectrum graph of the polysaccharides was similar to Polygonatum odoratum, Radix Ranunculi Ternati and Agrimonia pilosa Ledeb.
