The orthogonal design was adopted to optimize the extraction of isovanillin, periplocin and 4-methoxy salicylaldehyde. The optimal extracting condition was methanol consumed ten times the amount of material, and three times for 20 min each time.

采用正交试验设计，对香加皮提取工艺进行了优化，香加皮中异香草醛、杠柳毒苷和4-甲氧基水杨醛最佳提取工艺为：加入10倍量甲醇，超声提取3次，每次20min。

Isovanillin, 3-hydroxy- 4-methoxybenzaldehyde, and veratraldehyde, 3, 4-dimethoxybenzaldehyde are two sorts of significant perfumes of benzaldehyde. They have important effects on the markets of perfumes.

因此,探讨研究异香兰素和藜芦醛的合成路线是一项很有意义的课题。
