目的:对昭通产天麻Gastrodia elata Blume的化学成分进行研究。方法:采用硅胶柱层析、重结晶等方法分离纯化化合物,并运用现代波谱技术鉴定其结构。结果:从天麻中分离纯化得到14个化合物,分别鉴定为:对羟基苯甲醇(1)、对羟基苯甲醛(2)、3,4-二羟基苯甲醛(3)、4,4’-二羟基二苄基醚(4)、4-羟苄基-4’-羟基-3’-(4"-羟苄基)苄基醚(5)、对乙氧基苄醇(6)、对甲氧基苄醇(7)、二(3,4-二羟基苯基)甲烷(8)、4,4'-二羟基二苯基甲烷(9)、2,4-二-(4’-羟苄基)苯酚(10)、4-(甲氧甲基)苯-1,2-二酚(11)、对甲基苯-1—O-β-D-吡喃葡萄糖(12)、N6-(4'-羟苄基)-腺苷(13)、届.谷甾醇(14)。结论:其中,化合物6—8、11为首次从该植物中分离得到。
Objective: To study the chemical constituents of Gastrodia elata. Methods:The compounds were isolated by silica gel column chromatography and recrystallization and their structures were elucidated by spectral analysis. Results:The structures of 14 compounds were identified as : p-hydroxybenzyl alcohol ( 1 ), p-hydroxybenzaldehyde (2), 3,4-dihydroxybenzaldehyde ( 3 ), 4, 4'-dihydroxy, dibenzyl ether (4), 4-hydroxymethyl benzyl4'-hydroxy-3'-(4''-hydroxy benzl) benzyl ether (5), 4-ethoxybenzyl alcohol (6), anisic alcohol (7), bis ( 3, 4-dihydroxyphenyl ) methane ( 8 ), 4, 4'-dihydroxydiphenyl methane ( 9 ), 2, 4-bis ( 4'-hydroxy- benzyl)-phenol (10), 4-(methoxymenthyl) benzene-l, 2-diol (11), p-methylphenyl-1-O-β-D-glucopyranoside (12), N6-(4'- hydroxybenzl)-adenosine (13)and β-sitosterol (14). Conclusion: Compounds 6 -8 and 11 are isolated from this plant for the first time.
