Objective To analyze and compare the Eucommia ulmoides leaves from different producing areas by IR;To establish a TLC method for identification of Eucommia ulmoides leaves;To provide a reference for its quality control. Methods The characteristic absorption peaks were identified and the positions and intensities of Eucommia ulmoides leaves from 6 producing areas were compared by IR and second derivative spectrum, including clustering analysis; Separation and identification of the active components in Eucommia ulmoides leaves were conducted by TLC. Results There a difference exited in the characteristic absorption peaks in peakshapes, positions and intensities. And the samples from 6 producing areas could be divided into one category. Results found 6 batches of sample spots of consistent by TLC, but between samples of different producing areas trace components spots existed differences. Conclusion The two methods are direct, simple, fast and convenient, which can provide a reliable evidence for identification and quality control of the Eucommia ulmoides leaves.

Objective:To investigate frequency of blood stasis syndrome(BSS) defined by traditional Chinese medicine in cerebral infarction and its correlations with carotid atherosclerotic plaque(CAP).Methods: All subjects comprised 151 patients aged 40 to 80 years(Mean ? SD age,65 ?11 years) with 67.9% for males and 32.1% for females.With the use of ACUSON7 color Doppler ultrasound,carotid atherosclerosis was evaluated by the plaque score,the left plaque score,the right plaque score,the numbers of the plaque respectively as defined by the sum of all plaque heights in bilateral carotid arteries.On the basis of neurological signs and symptoms,medical history,and brain MRI,we diagnosed stroke and its subtypes as follows: stroke(n=117),and vertebrobasilar insufficiency(VBI)(n=34) without the history of the stroke,which were based on Diagnostic Criteria for Cerebral Vascular Diseases in 2005.Diagnosis for syndromes defined by traditional Chinese medicine were made according to Diagnostic Criteria for Stroke in 1994.One-way ANOVA was used in comparison between groups,and multivariant Logistic Regression Analysis was conferred in correlations between several variables.Results: 47.0% of all cases with cerebral infarction presented the BSS,with as lower than syndrome of fire-heat(51.0%),as but significantly higher than syndrome of Qi deficiency(32.0%),liver-wind syndrome(27.0%),phlegm syndrome(23.0%) and syndrome of asthenic yin causing predominant yang(6.0%).There is a significant difference between groups for 44(79.0%) cases of 56 patients with cerebral infarction and the BSS have CAP,and only 35(57.0%) cases of 61 patients with cerebral infarction but without the BSS have CAP(P
