Abstract Novel acylatedglycerolglucosides, regaloside A and B, both bitter to the taste, have been isolated from the fresh bulbs of Liliumregale. Their structures have been shown by the spectral and chemical evidence to be (2S)-1-O-p-coumaroyl-3-O-β- d -glucopyranosylglycerol and (2S)-1-O-p-coumaroyl-2-O-β-d-glucopyranosyl-3-O-acetylglycerol, respectively.
摘要 从新鲜百合球茎中分离到了新的酰化甘油糖苷,即 Regaloside A 和 B,它们都具有苦味。它们的结构已通过光谱和化学证据显示为 (2S)-1-Op-coumaroyl-3-O-β-d-吡喃葡萄糖基甘油和 (2S)-1-Op-coumaroyl-2-O-β-d -吡喃葡萄糖基-3-O-乙酰甘油,分别。
