All data indicated that f i was a pure substance. third, using modern analytic techniques such as nucleic magnetic resonance ( nmr ), infrared spectroscopy ( ir ), ultraviolet visible absorption spectra ( uv ) and mass spectrometry ( ms ), we analyzed the basic chemical structure of f i and nominated it phthalic acid di ( 3 - methyl ) nanyl ester ( pdne ). we estimated primarily it was a novel natural compound
第三,利用核磁共振,紅外光譜,紫外分析,質譜等現代分析測試技術對分離提取物f進行結構鑒定,解析出f的結構,初步推斷該物質為鄰苯二甲酸- ( 3 -甲基)壬酯( pdne ) ,根據目前所掌握的資料,還沒有檢索到該物質相關的報道,初步認定為一種新型的天然產物。 -
