Measurement of Sarcandra Glabra Based on Surface Enhanced Raman Spectroscopy
摘要
Abstract
Sarcandra glabra is one of the traditional Chinese medicine.A method was demonstrated to measure it by surface enhanced Raman spectrum (SERS) technology.Silver colloid was prepared by using aqueous reduction of silver nitrate with trisodium citrate.SERS in the samples of Sarcandra glabra was detected by taking silver nanoparticles as enhancing substrates.After disposed by the silver colloid,the intensity of the SERS signal of Sarcandra glabra stem section increased obviously.In SERS of Sarcandra glabra samples,the characteristic peaks were observed at 637,1 176,1 309,1 476,1 612 cm-1 The SERS signal of Sarcandra glabra was assigned tentatively to some biochemical substances and molecular structure including benzopyrone ring,methoxy and phenolic hydroxyl group through a derivative spectrum of Sarcandra glabra and Isofraxiden.The results show that the SERS might provide a new,precise and convenient method for the research of tradition Chinese medicinal materials.关键词
