摘要

摘要目的苯甲醛存在于许多植物中，尤其是蔷薇科，尤其是李属。在自然界中，蔷薇科有100多属3000多种。本研究的目的是研究桃（Prunus persica L.）和樱桃月桂（Pruns laurocerasus L.）的叶精油的化学成分，这两种植物是天然苯甲醛的新的潜在来源。方法采用加氢蒸馏法制备挥发油，采用气相色谱-火焰离子化检测器、气相色谱法测定挥发油的化学成分，并对其色谱图谱进行比较。结果从桃和樱桃月桂叶中提取的精油是一种很有前景的天然苯甲醛来源。在实验室条件下，桃和樱桃月桂叶中苯甲醛含量分别达到95.5%和99.7%。结论实验室和中试实验证实，对200～300kg不同种类的李属植物，特别是桃和樱桃月桂的绿叶进行加工，可获得1kg的苯甲醛。

The Use of Enzyme Systems of the Genus Prunus for the Production of Benzaldehyde

Abstract Aim Benzaldehyde occurs in a number of plants, especially in the family Rosaceae and in particular in the genus Prunus. In nature, there are more than 100 genera and 3,000 species in the Rosaceae family. The objective of this study was to investigate the chemical composition of leaf essential oil of peach (Prunus persica L.) and cherry laurel (Prunus laurocerasus L.) as a new potential source of natural benzaldehyde. Methods The essential oil was prepared by hydrodistillation, and chemical constituents were determined by GC-FID, GC-MS and chromatographic profiles were compared with each other. Results The results show that essential oil obtained from peach and cherry laurel leaves appear to be a promising source of natural benzaldehyde. Under laboratory conditions the benzaldehyde content in peach and cherry laurel leaves reached 95.5% and 99.7%, respectively. Conclusions Laboratory and pilot experiments confirmed that by processing of 200–300 kg of green leaves of various species of the genus Prunus, especially peach and cherry laurel, 1 kg of benzaldehyde can be obtained.
