Abstract: In order to prepare natural benzaldehyde from amygdalus ledebouriana schleche in Xinjiang, the UV absorb method is used to determine the content of benzaldehyde and inspect its efficiency of preparation by steam distillation after getting rid of the fat in amygdalus ledebouriana schlecht by ultrasonic method. The content of natural benzaldehyde in amygdalus ledebouriana schlecht is 1.264%.The average recovery of preparation is 83.99% and RSD is 3.0%. The practical average productivity of natural benzaldehyde reaches 83.60% and RSD is 1.7%. So to prepare natural benzaldehyde under the conditions is available and the recovery is steady.

Key words: amygdalus ledebouriana schleche, natural benzaldehyde: preparation
