基于直观推导式演进特征投影（ＨＥＬＰ）法，对冬虫夏草子座和虫体分别进行了多组分同时定性定量测定．结果表明，ＨＥＬＰ法能减少样本提取分离的步骤，降低色谱分离条件的要求，提高检测准确度．联用色谱检测与化学计量学解析法相结合将为复杂中草药分析提供一种全新手段
Based on the intuitive derivation evolution feature projection (HELP) method, simultaneous qualitative and quantitative determinations of multiple components of Cordyceps sinensis and its parasites were performed. The results show that the HELP method can reduce the steps of sample extraction and separation, reduce the requirements of chromatographic separation conditions, and improve the detection accuracy. The combination of combined-use chromatographic detection and chemometric analysis will provide a new approach to the analysis of complex Chinese herbal medicines
