Abstract:
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.
