          摘   要 目的 分离、鉴定海州常山茎正丁醇部位的化学成分,并考察其体外抗肿瘤活性。方法 使用85%乙醇回流提取海州常山
          的干燥茎得到其乙醇提取物。将所得乙醇提取物用水分散后,依次用石油醚、乙酸乙酯和正丁醇萃取,减压浓缩后分别得到各萃
          取部位浸膏。采用D101大孔树脂柱层析以及包括硅胶、羟丙基葡聚糖凝胶和Toyopearl HW-40F大孔树脂等在内的各种色谱技术
          对海州常山茎正丁醇部位进行分离纯化,并结合化合物的物理、化学性质以及质谱、核磁共振谱等波谱技术确定其结构。采用
          MTT法检测所得化合物对4种人源肿瘤细胞K562、MCF-7、A549和HepG2的增殖抑制活性。结果 从海州常山茎85%乙醇提取
          物的正丁醇部位共分离鉴定出14个化合物,分别鉴定为teuvincenone B(1)、钩大青酮(2)、villosin C(3)、丁香脂素(4)、丁香脂素-
          4′-O-β-葡萄糖(5)、3,12-O-β-D-二吡喃葡萄糖基-11,16-二羟基松香醇-8,11,13-三烯(6)、五叶山小橘苷C(7)、角胡麻苷(8)、异地
          黄苷(9)、2-(4-hydroxyphenyl)ethanol-O-β-D-glucopyranosyl-(1→2)-O-β-D-glucopyranoside(10)、3,4-二甲氧基苯基-1-O-β-D-呋喃
          芹糖基-(1→2)-β-D-葡萄糖苷(11)、2,6-二甲氧基-4-羟苯基-1-O-β-D-吡喃葡萄糖苷(12)、腺苷(13)和肉苁蓉苷F(14)。体外抗肿
          瘤活性研究表明,化合物1~3具有一定的抗肿瘤活性,其中化合物2对MCF-7、A549和HepG2细胞的增殖抑制活性最强,半数抑
          制浓度(IC50 )分别为 25.00、22.34、12.50 μmol/L;化合物 3 对 K562 细胞的增殖抑制活性较强,IC50为 28.41 μmol/L。结论 化合物
          10~13为首次从该属植物中分离得到,化合物4、5、14为首次从该植物中分离得到;松香烷型二萜类化合物(化合物1~3)对上述
          4种肿瘤细胞株的增殖抑制活性较好。

          ABSTRACT    OBJECTIVE To separate and identify the chemical constituents of the n-butanol fraction from the stems of
          Clerodendrum trichotomum,and to investigate their antitumor activities in vitro. METHODS The ethanol extracts were obtained
          with 85% ethanol from dried stems of C. trichotomum. After dispersed with water,ethanol extracts were distributed by petroleum
          ether,ethyl acetate and n-butanol in turn,then concentrated under reduced pressure to obtain the fractions of each extraction part.
          The n-butanol fraction from the stems of C. trichotomum was isolated and purified by macroporous resin D101 column
          chromatography and various chromatographic techniques including silica gel,hydroxypropyl glucan gel and Toyopearl HW-40F
          macroporous resin and so on. The structures of them were identified by physical and chemical properties,MS and NMR. All these
          compounds were evaluated for cytotoxic activities against 4 kinds of human tumor cells such as cultured K562,MCF-7,A549 and
          HepG2,using the MTT assay. RESULTS Fourteen chemical constituents were isolated and identified as teuvincenone B(1),
          uncinatone(2),villosin C(3),syringaresinol(4),syringaresinol-4ʹ-O-β-glucopyranoside(5),3,12-O-β-D-diglucopyranosyl-11,16-
