摘要
目的:研究炮制对荷叶中荷叶碱和槲皮素含量的影响。方法:以荷叶碱和槲皮素含量为指标,对荷叶生品、煅炭品及炒炭品进行比较,采用HPLC法测定荷叶碱和槲皮素含量。结果:荷叶经煅炭和炒炭后,荷叶碱含量较生品依次降低99.52%和99.23%,槲皮素含量较生品依次增加608.56%和643.85%。结论:加热炮制对荷叶中荷叶碱和槲皮素含量有显著影响。
AIM： To study the effect of the processing on the contents of nuciferine and quercetin existed in lotus leaf（Nelumbo nucifera Gaertn）.METHODS： Nuciferine and quercetin were allowed for the markers and its contents were assayed by HPLC.Marker constituents were compared among raw herb,carbonizing by stir-frying and carbonizing by calcining.RESULTS： By means of carbonizing processing,nucifering content of lotus leaf reduced to 99.25% and 99.23% compared with the unprocessed lotus leaf,quercetin content of lotus leaf increased to 608.56% and 643.85% compared with the unprocessed lotus leaf.CONCLUSION： The heating processing has remarkable effect on the contents of nuciferine and quercetin in Nelumbo nucifera Gaertn.
