ABSTRACT
<p><b>OBJECTIVE</b>To analyze and identify fatty acids in the seeds of Sterculia lychnophora.</p><p><b>METHOD</b>The compositions was isolated and determined by GC-MS technique, and area normalization method was used to make quantitative analyze of the content of compositions.</p><p><b>RESULTS</b>21 Fatty acids and 5 other compositions were isolated and determined.</p><p><b>CONCLUSION</b>The major fatty acids are 9,12(Z,Z)-octadecadienoic acid(37.96%), hexadecanoic acid(24.77%), 9-(Z)-octadecenoic acid(19.77%) and octadecanoic acid(5.01%).</p>

<p><b>OBJECTIVE</b>To study the chemical constituents from the seed of Trigonella foenum-graecum.</p><p><b>METHOD</b>The compounds were isolated with silica gel chromatography and their structures were identified by physical, chemical properties and spectral analysis.</p><p><b>RESULT</b>Seven compounds were isolated and identified as N,N'-dicarbazyl, glycerol monopalmitate, stearic acid, beta-sitosteryl glucopyranoside, ethyl-alpha-D-glucopyranoside, D-3-O-methyl-chiroinsitol and sucrose.</p><p><b>CONCLUSION</b>All the compounds were obtained from this plant for the first time and N,N'-dicarbazyl is a new natural product.</p>
