In Chinese folk medicine, TPSs are used for alleviating waist and leg pain. In the present study, a simple, accurate and rapid fingerprint method based on high performance liquid chromatography with diode array detection（HPLe-DAD） was developed and validated to quantify the profiles of ten representative compounds in TPSs. All standard calibration curves exhibited good linearity（R2〉0.9995） in the I-IPLC-DAD analysis. The recovery of the standards ranged from 96.37% to 102.10%. The results show that stilbe- noids are the major constituents in TPSs, and their total content ranges from 25.71 mg/g to 54.03 mg/g. Suffruticosol A, suffruticosol B, trans-e-viniferm, ampelopsin E and paeoniflorin are the major components in methanol- water（80：20, volume ratio） extracts with average contents of 3.962, 12.264, 5.826, 14.060 and 12.755 rag/g, respec- tively. Additionally, 14 batches of seeds collected from different regions were used to establish a reference fingerprint Their similarity values were higher than 0.944 except for the sample（0.863） from Linxia. These results collectively indicate that the quantitative HPLC fingerprint method can serve as a prerequisite quality control for TPSs, and is a promising resource for developing new herbal or food products.展开更多
为了推动油用牡丹产业的发展,优化油用牡丹种植技术。以油用牡丹“凤丹”作为试验材料,在聊城大学农学院植物种植园和试验室内进行采集、试验分析,利用不同氮素添加水平:不施氮(N0),施氮5 kg N/hm~2(N1)、10 kg N/hm~2(N2)、15 kg N/hm~...为了推动油用牡丹产业的发展,优化油用牡丹种植技术。以油用牡丹“凤丹”作为试验材料,在聊城大学农学院植物种植园和试验室内进行采集、试验分析,利用不同氮素添加水平:不施氮(N0),施氮5 kg N/hm~2(N1)、10 kg N/hm~2(N2)、15 kg N/hm~2(N3)、20 kg N/hm~2(N4)和25 kg N/hm~2(N5)对牡丹幼苗进行处理,得到了根系性状的数据表明:适量增施氮肥,可有效提高幼苗根系同化物积累量,过量增施氮肥又呈下降趋势;随着氮素的增加,根系总表面积、磷素含量、根尖数和分叉数均表现不同程度先升高后降低的趋势;幼苗根系氮素含量随着施氮量的增加前期上升缓慢、中期无明显差异、后期上升迅速,总体呈不断上升的趋势。因此,为保证“凤丹”牡丹幼苗根系吸收能力和正常发育,进而促进“凤丹”牡丹稳产高产,最佳的施氮量为10 kg N/hm~2(N2)。展开更多
