| 摘要: |
| 目的 研究鸡头黄精(Polygonatum sibiricum Red.)根茎的化学成分及其相关活性。方法 采用凝胶柱色谱、硅胶柱色谱、半制备高效液相色谱等技术进行分离和纯化,根据其理化性质和波谱数据对得到的化合物进行结构鉴定。采用对硝基苯基-β-D-吡喃葡萄糖苷(PNPG)法、2,2'-联氮双(3-乙基苯并噻唑啉-6-磺酸)二铵盐(ABTS)试剂盒,分别评价所得化合物的α-葡萄糖苷酶抑制活性、抗氧化活性。结果 从鸡头黄精石油醚提取物和乙酸乙酯提取物中分离并鉴定得到15个化合物,分别鉴定为disporopsin(1)、5,7-二羟基-6,8-二甲基-3-(4'-羟基苄基)苯并二氢吡喃-4-酮(2)、5,7-二羟基-6-甲基-3-(4'-羟基苄基)苯并二氢吡喃-4-酮(3)、polygonatone H(4)、4'-demethylleucomin-7-O-β-D-glucopyranoside(5)、4-氨基肉桂酸(6)、对羟基苯甲酸(7)、6,7-二甲氧基-4-羟基-1-萘酸(8)、丁香脂素(9)、蔗糖(10)、3β,22α-二羟基-7β-甲氧基-24β-乙基胆甾-5-烯(11)、豆甾-5-烯-3β,7α-二醇(12)、β-谷甾醇(13)、β-胆甾酮(14)、24-乙基-5α-胆甾-3β,5,6β-三醇(15)。化合物1、4、5对α-葡萄糖苷酶具有抑制活性,其IC50值分别为(23.47±1.30)、(51.24±2.41)、(83.74±15.77) μmol/L;化合物1、2、4、8具有ABTS自由基清除能力,IC50值分别为(14.39±1.77)、(23.76±2.27)、(24.51±2.49)、(11.57±1.03) μmol/L。结论 化合物2、4、6、8、9、11、15为首次从鸡头黄精中分离得到。化合物1~5为较少见的高异黄酮类化合物,且该类化合物在α-葡萄糖苷酶抑制、抗氧化方面具有潜在活性。 |

| Abstract: |
| Objective To study the chemical constituents of the rhizomes of Jitou Huangjing (JTHJ, Polygonatum sibiricum Red), and their associated biological activities. Methods Gel column chromatography, silica gel column chromatography, and semi-preparative high-performance liquid chromatography (HPLC) were used to isolate and purify the chemical constituents of JTHJ. The obtained compounds' structures were identified by physicochemical properties and spectral data. Their α-glucosidase inhibitory and antioxidant activities were evaluated by p-Nitrophenyl-β-D-glucopyranoside (PNPG) assay and 2, 2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assay kit, respectively. Results 15 compounds were isolated and identified from the petroleum ether and ethyl acetate extracts of JTHJ, namely disporopsin (1), 5, 7-dihydroxy-6, 8-dimethyl-3-(4'-hydroxybenzyl)chroman-4-one (2), 5, 7-dihydroxy-6-methyl-3-(4'-hydroxybenzyl) chroman-4-one (3), polygonatone H (4), 4'-demethylleucomin-7-O-β-D-glucopyranoside (5), 4-aminocinnamic acid (6), p-hydroxybenzoic acid (7), 6, 7-dimethoxy-4-hydroxy-1-naphthoic acid (8), syringaresinol (9), sucrose (10), 3β, 22α-dihydroxy-7β-methoxy-24β-ethyl-cholest-5-ene (11), stigmast-5-ene-3β, 7α-diol (12), β-sitosterol (13), β-sitostenone (14), 24-ethyl-5α-cholestane-3β, 5, 6β-triol (15). Compounds 1, 4, 5 showed α-glucosidase inhibitory activity, with IC50 values of (23.47±1.30), (51.24±2.41), (83.74±15.77) μmol/L, respectively. Compounds 1, 2, 4, 8 exhibited ABTS radical scavenging activity, with IC50 values of (14.39±1.77), (23.76±2.27), (24.51±2.49), (11.57±1.03) μmol/L, respectively. Conclusion Compounds 2, 4, 6, 8, 9, 11, and 15 were isolated from JTHJ for the first time. Compounds 1-5 belong to the relatively rare class of homois-oflavonoids with potential α-glucosidase inhibitory and antioxidant activities. |
