To provide the human being with safe drinking water is one of the most important issues in public health. In response to the more and more serious pollution of algal toxins, growing concern has been attached to the water bodies contaminated with algal toxins and the effects posed on human health. Drinking water suppliers are confronted with the important problem of how to remove the toxins to the acceptable levels. Conventional water treatment procedures are not efficient in removing toxins. Activated carbon adsorption, membrane filtration, photocatalic process, ozonation and chlorination are effective in removing cyanobacterial toxins, but each has its limitation.

OBJECTIVE:To interpret the contribution of Sun Simiao Qianjin Yi Fang to herbalism. METHODS:Using“Sun Simiao”“Qianjin Yi Fang”“herbalism”and other words as key words,related literatures were retrieved from CNKI,Wanfang,Dayi Yixue database and so on during 1983-2015;four aspects explained in Qianjin Yi Fang by Sun Simiao were summarized,involving“herb gathering season ranking the first”“nomen proprium ranking the second”“herb source ranking the third”and“prescription rank-ing the forth”. RESULTS & CONCLUSIONS:More than 50 literatures were collected,including 14 effective literatures. It is the quintessence of precious experience that herbalism is placed in the front of Sun Simiao Qianjin Yi Fang,which greatly contributes to herbalism.“Herb gathering season ranking the first”is the true essence of herb quality guarantee;“nomen proprium ranking the second”guarantees accurate use of herb in the clinic fundamentally;“herb source ranking the third”lays the foundation of therapeu-tic efficacy;“prescription ranking the forth”creates a new era of herb classification by functions.

OBJECTIVETo develop a HPCE analysis method for fingerprints of Forsythia suspensa from Hebei province, get reference fingerprint and compare the fingerprints of F. suspensa collected from different producing areas and different parts of the plant.

METHODElectrophoresis was performed on a fused silica capillary column (75 microm x 60 cm, 30 cm). The running buffer was composed of 50 mmol x L(-1) borax (adjust to pH 9.90 with 0.1 mol x L(-1) NaOH). The applied voltage was 15 kV and the temperature was 20 degrees C. The detection wavelength was 214 nm. The semblances to the crude drugs of different producing areas were compared.

RESULTThe mutual mode of HPCE fingerprints was set up with 12 common peaks. The fingerprints of F. suspensa from Hebei province had high similarity, F. suspensa from Shanxi and Henan were also of good quality. The chemical composition in different parts of the herb had big differences.

CONCLUSIONThe method is simple, quick, accurate and can be used as a new means for the quality control of F. suspensa.
