A SIMPLE AND EASY DEVICE FOR VOLATILE OIL CONTENT MEASUREMENT

Objective: A simple apparatus for volatile oil determination is designed with the use of common glass apparatus in order to refreshen the shortcoming of pharmacopoeia device. Methods: This device was used to measure the volatile oil content of common medicinal herbs by coeno-water distillation and compared with the results measured by pharmacopoeia device; at the same time, their applicability was compared. Results: The extraction efficiency of this method is basicly consistent with that of the pharmacopoeia method, and it possesses the advantage that the practical scope is extensive, and the precision is high , and it can be used in microdetermination etc. Conclusion: This apparatus possesses great application and popularization value.
