中文摘要：
目的 对中药色谱指纹图谱潜信息特征进行判据研究，用F和I等37个指标揭示色谱指纹图谱的潜信息特征。方法 用银杏叶提取物（GBE）、银杏达莫注射液（GLEDI）和苦碟子（ISH）与苦碟子注射液（ISHI）的HPLC指纹图谱进行比较研究。结果 从积分信号强度、信号均化程度、分离度、指纹信息量等多方面综合评价出GBE指纹图谱好于GLEDI，ISH指纹图谱好于ISHI，GBE与ISH指纹图谱基本相当。结论 F和I等37个指标可客观、真实、全面地揭示中药指纹图谱的潜信息特征。
英文摘要：
Aim To exploit the characteristic digital criterion for the potential information characteristics of traditional Chinese medicine chromatographic fingerprints, the 37 parameters such as F and I were firstly proposed to disclose the potential information characteristics of traditional Chinese medicine fingerprints. Methods The HPLC fingerprints of the Ginkgo biloba extract （GBE） , Ginkgo leaf extract and diphyridamole injection （GLEDI） , lxeris sonchifolia Hance （ISH） and lxeris sonchifolia Hance injection （ISHI） were compared each other. Results As far as the peak signal intensity, the uniform of peak signal, resolution and the fingerprint information were concerned. The GBE fingerprint was better than the GLEDI＇ s, and the ISH fingerprint was also better than the ISHI＇ s, then GBE fingerprint was close to the ISHI＇ s. Conclusion The 37 parameters such as F and I can be used to objectively, authentically and thoroughly display the potential information characteristics of the traditional Chinese medicine chromatographic fingerprints.
