目的:根据气味鉴别不同产地栽培及野生喜马拉雅紫茉莉。方法:利用电子鼻检测喜马拉雅紫茉莉样品气味在传感器上的响应值,采用判别因子分析(DFA)、分层聚类分析(HCA)、人工神经网络(ANN)等方法分析。结果:不同产地栽培及野生喜马拉雅紫茉莉气味差异明显。结论:电子鼻技术能用于区分不同产地栽培及野生喜马拉雅紫茉莉,电子鼻技术可以引入到藏药的质量评价中来。 Purpose: To identify cultivated and wild Himalayan Mirabilis from different origins based on their odor. Methods: The response of sensor to sensorial odor of Mirabilis jalapa in Himalayas was detected by electronic nose, and analyzed by DFA, HCA and ANN. Results: There were significant differences in smell of Mirabilis jalapa between different habitats and wild Himalayas. Conclusion: Electronic nose technology can be used to distinguish between cultivated and wild Mirabilis jalapa in different habitats. Electronic nose technology can be introduced into the quality evaluation of Tibetan medicine.
