[Objective] To establish a Folin-Ciocaileu method for determination of the contents of total hydroxybenzene in antioxidant effective fraction of leaves of Lonicera Hypoglauca Miq. which is used in the exploration of the content changes of total hydroxybenzene in antioxidant effective fraction of leaves of Lonicera Hypoglauca Miq. of different batches. [Methods]The methodology of the method for determination of the contents of total hydroxybenzene in water extraction of leaves of Lonicera Hypoglauca Miq. was investigated by Folin-Ciocaileu method. The contents of total hydroxybenzene in water extractions or the precipitation and filtrate of 30%ethanol precipitating action from 12 batches of leaves of Lonicera Hypoglauca Miq. were determined.[Results] The methodological study showed that the linear range of total hydroxybenzene was 6 μg·mL-1~16 μg·mL-1 (r=0.9996). The repetitiveness RSD of total polyphenol was 0.31%(n=6). In addition, the average recovery of total polyphenol was 98.67%, with RSD 2.66%(n=9). The total hydroxybenzene contents in different batches extraction of leaves of Lonicera Hypoglauca Miq. were quite different. While the contents of total hydroxybenzene in the same leaves of Lonicera Hypoglauca Miq. were: water extraction>the filtrate of 30% ethanol precipitating action>the precipitation of 30% ethanol precipitating action.[Conclusions]The method is simple, accurate, reproducible and suitable for simultaneous determination of the contents of total polyphenol in antioxidant effective fraction of leaves of Lonicera Hypoglauca Miq.. The total hydroxybenzene contents in various extraction of leaves of Lonicera Hypoglauca Miq. were water extraction>the filtrate of 30% ethanol precipitating action>the precipitation of 30% ethanol precipitating action.
