Abstract
This study was carried out to investigate the morphological properties and pyrrolizidine alkaloids of comfrey cultivating in Korea. 12 comfrey samples cultivation in Korea was selected and their appearance (whole plant, leaves, root etc.) were observed by expert and microscopy for morphological analysis. It is confirmed that their species are Symphytum officinale Linnaeus. Samples were extracted by hot MeOH and ultra-sonification. Their extracts contained pyrrolizidine alkaloids, which was identified by TLC analysis. By spraying thin-layer chromatograms of pyrrolizidine alkaloids stable purple spots were developed. But the extracts of chicory, pumpkin and sesame leaves did not show any purple spots. Same HPLC pattern were displayed at about 30 min of retention show peaks an one and the same time.
