目的 研究独蒜兰Pleione bulbocodioides假鳞茎的主要化学成分及抗炎活性。方法 通过LC-MS分析主要成分;使用硅胶柱、Sephadex LH-20凝胶柱色谱、制备薄层色谱、半制备液相色谱等分离技术进行分离纯化,通过波谱技术并结合文献对化合物进行结构鉴定;采用脂多糖(lipopolysaccharide,LPS)诱导的RAW264。7小鼠单核巨噬细胞体外炎症模型进行抗炎活性评价。结果 分离得到20个化合物,分别鉴定为对羟基苄基乙醚(1)、对羟基苯甲醛(2)、4-(甲氧基甲基)苯1,2-二醇(3)、3,4-二羟基苯甲醛(4)、对羟基苯乙醇(5)、反式阿魏酸(6)、山药素Ⅲ(7)、3,3'-二羟基-5-甲氧基-2,6-二(对羟基苄基)联苄(8)、3',5-二羟基-3-甲氧基-2-(对羟基苄基)联苄(9)、3,3'-二羟基-5-甲氧基-2-(对羟基苄基)联苄(10)、bletistrin D(11)、4-烯丙基-2,6-二甲氧基苯基葡萄糖苷(12)、1-O-(4-羟甲基苯氧基)-2-O-反式肉桂酰-β-D-葡萄糖苷(13)、1-O-(4-羟甲基苯氧基)-6-O-反式肉桂酰-β-D-葡萄糖苷(14)、militarine(15)、bletistroside D(16)、天麻素(17)、1-[4'-O-(β-D-吡喃葡萄糖基)苄基]-2-O-(β-D-吡喃葡萄糖基)-4-{4'-O-[(3'-O-反式阿魏酰基)-β-D-吡喃葡萄糖基]苄基}-(2R)-2-异丁基琥珀酸酯(18)、bletistroside C(19)和dactylorhin A(20)。对化合物7、8、15、16、18~20进行了抗炎活性筛选,化合物7、15、20在50μmol/L时对NO的抑制率达到42。5%、23。1%和23。6%。结论 化合物18为新化合物,命名为白及琥珀酯苷M(bletistroside M),化合物8、11~14、16和19均是首次从该植物中分离得到;LC-MS显示独蒜兰的主要化学成分是山药素III(7)、militarine(15)和dactylorhin A(20)。此外,化合物7对LPS诱导的RAW264。7细胞炎症反应的抑制作用最好。
A new glucosyloxybenzyl derivative from Pleione bulbocodioides and anti-inflammatory activity
Objective To study the main chemical constituents of Pleione bulbocodioides and the anti-inflammatory activities. Methods The main compounds were analyzed by LC-MS;Silica gel column,Sephadex LH-20 gel column chromatography,preparative thin-layer chromatography and semi-preparative liquid chromatography were used to isolate and purify these compounds. The structures of the isolated compounds were identified by spectroscopy (MS and NMR) methods;All the isolates were tested for the anti-inflammatory activities using the lipopolysaccharide (LPS)-activated of RAW264.7 cells. Results A total of 20 compounds were isolated and identified as p-hydroxybenzyl ethyl ether (1),p-hydroxybenzaldehyde (2),4-(methoxymethyl)benzene-1,2-diol (3),3,4-dihydroxybenzaldehyde (4),p-hydroxylbenzyl alcohol (5),(E)-ferulic acid (6),batatasin Ⅲ (7),3,3'-dihydroxy-5-methoxy-2,6-bis(p-hydroxybenzyl)bibenzyl (8),3',5-dihydroxy-3-methoxy-2-(p-hydroxybenzyl)bibenzyl (9),3,3'-dihydroxy-5-methoxy-2-(p-hydroxybenzyl)bibenzyl (10),bletistrin D (11),4-allyl-2,6-dimethoxyphenyl glucoside (12),1-O-(4-hydroxymethylphenoxy)-2-O-trans-cinnamoyl-β-D-glucoside (13),1-O-(4-hydroxymethylphenoxy)-6-O-trans-cinnamoyl-β-D-glucoside (14),militarine (15),bletistroside D (16),gastrodin (17),1-[4'-O-(β-D-glucopyranosyloxy) benzyl)-2-O-(β-D-glucopyranosyloxy)-4-{4'-O-[(3'-O-(E)-feruloyl)-β-D-glucopyranosyloxy]benzyl}-(2R)-2-isobutylsuccinate (18),bletistroside C (19) and dactylorhin A (20). Compounds 7,8,15,16,18—20 are screened for anti-inflammatory activity. Compounds 7,15 and 20 showed 42.5%,23.1% and 23.6% inhibition of NO at 50 μmol/L. Conclusion Compound 18 is identified as a novel compound and named bletistroside M;Compounds 8,11—14,16 and 19 are obtained from this plant for the first time;LC-MS showed that the main chemical constituents were batatasin Ⅲ(7),militarine (15) and dactylorhin A (20). In addition,compound 7 showed the best anti-inflammatory effects.
