摘要 为研究民间药冷饭藤的化学成分,采用硅胶、MCIHP20凝胶、SephadexLH.20凝胶等柱色谱技术对其藤茎的70%丙酮提取物进行分离和纯化,得到20个化合物,根据化合物的理化性质和波谱数据鉴定化学结构为:heteroclitalignanA(1)、kadsulignanF(2)、kadoblongifolinC(3)、schizanrinF(4)、heteroclitalignanC(5)、kadsurarin(6)、kadsulignanO(7)、eburicol(8)、meso-dihydroguaiareticacid(9)、kadsufolinA(10)、tiegusaninM(11)、heteroclitinB(12)、(7’回-parabenzlactone(13)、angeloylbinankadsurinB(14)、propinquainH(15)、quercetin(16)、kadsulignanP(17)、schizanrinG(18)、micrandilactoneC(19)和(-).shikimicacid(20)。化合物1、5、8、11~15、18、20为首次从冷饭藤中分离得到。本文应用斑马鱼模型对化合物1~10进行毒性评价,观察其对斑马鱼胚胎发育、心脏功能的影响,发现经化合物7、9和10处理后,斑马鱼胚胎出现水肿、心率明显下降,说明化合物7、9和10对斑马鱼心脏发育具有干扰作用。 To study the chemical constituents of K. oblongifolia, silica gel column chromatography, MCI and Sephadex LH-20 were used to separate the 70% acetone extract of the stems of K. oblongifolia. The structures of the isolated compounds have been established on the basis of physicochemical and NMR spectroscopic evidence as well as ESI-MS in some cases. Twenty compounds were obtained and identified as heteroclitalignan A (1), kadsulignan F (2), kadoblongifolin C (3), schizanrin F (4), heteroclitalignan C (5), kadsurarin (6), kadsulignan O (7), eburicol (8), meso-dihydroguaiaretic acid (9), kadsufolin A (10), tiegusanin M (11), heteroclitin B (12), (7'S)-parabenzlactone (13), angeloylbinankadsurin B (14), propinquain H (15), quercetin (16), kadsulignan P (17), schizanrin G (18), micrandilactone C (19) and (-)-shikimic acid (20). Compouds 1, 5, 8, 11-15, 18 and 20 were isolated from this plant for the first time. Toxicity of compounds 1-10 were evaluated with zebrafish model to observe the effect on its embryonic development and heart function. The results showed that compounds 7, 9 and 10 caused edema of zebrafish embryo and decreased the heart rate of zebrafish,which exhibited interference effect on heart development of zebrafish.
