从珊瑚兰(Galeola faberi Rolfe)根茎的乙醇提取物中首次分离鉴定出五个脂溶性酚类衍生物(Ⅰ～Ⅴ)和三个水溶性酚类衍生物(Ⅵ～Ⅷ),即:对羟基苯甲醛(Ⅰ)、4,4′-二羟基二苯基甲烷(Ⅱ)、2,4-二对羟苄基苯酚(Ⅲ)、5-甲氧基-3-(2-苯基-反-乙烯基)-2,4-二对羟苄基苯酚(Ⅳ)、对羟基苯甲醇(Ⅴ)、对羟甲基苯-β-D-吡喃葡萄糖甙(天麻素,Ⅵ)、二[4-(β-D-吡喃葡萄糖氧)苄基](S)-(-)-2-异丙基苹果酸酯(Ⅶ)和二[4-(β-D-吡喃葡萄糖氧)苄基](S)-(-)-2-仲丁基苹果酸酯(Ⅷ)。其中Ⅳ和Ⅷ为新化合物,Ⅲ为新天然产物。
Five lipid-soluble phenolic derivatives (I-V) and three water-soluble phenolic derivatives (VI-VIII) were isolated and identified from the ethanol extract of the root of Galeola faberi Rolfe for the first time. Benzaldehyde (I), 4,4’-dihydroxydiphenylmethane (II), 2,4-di-p-hydroxybenzylphenol (III), 5-methoxy-3-(2-phenyl-anti) -vinyl)-2,4-bis-p-hydroxybenzyl phenol (IV), p-hydroxybenzyl alcohol (V), p-hydroxymethyl benzene-β-D-glucopyranoside (gaspsin, VI), di 4-(β-D-glucopyranosyloxy)benzyl](S)-(-)-2-isopropylmalate (VII) and di[4-(β-D-glucopyranoxy)benzyl] Based on (S)-(-)-2-sec-butyl malate (VIII). Among them, IV and VIII are new compounds, and III is a new natural product.
