Chemical study on the bulbs of Lilium (L.) mackliniae has led to the isolation of a total of 27 compounds, including nine new phenolics. The structures of the new compounds have been shown by spectral analysis and chemical degradation to be 4,4'-di-O-acetyl-3,6'-di-O-feruloylsucrose, 3,4'-di-O-p-coumaroylsucrose, 3,6'-di-O-p-coumaroylsucrose, 2'-O-acetyl-3,4'-di-O-p-coumaroylsucrose, 3'-O-acetyl-3,4'-di-O-p-coumaroylsucrose, (2S)-1-O-p-methoxycinnamoyl-2-O-β-D-glucopyranosylglycerol (methylregaloside D), (2S)-1-O-cinnamoyl-2-O-β-D-glucopyranosyl (regaloside J), (2S)-l-O-caffeoyl-2-Oβ-D-glucopyranosylglycerol (regaloside K) and (2R)-1-O-β-D-glucopyranosyl-2-O-caffeoylgly-cerol (regaloside L). In addition, several previously reported phenolic glycosides, steroidal saponins and steroidal alkaloid have been isolated and identified. The presence of the steroidal alkaloid supported the idea that L. mackliniae is taxonomically related to the genus Fritillaria.
