This study was designed to investigate the chemical constituents of the anti-osteoporotic part of Lepidium meyenii Walp. (maca) produced in Heqing, Yunnan. Seven compounds were isolated from the n-BuOH extract of maca using combination of column chromatographies on MCI resin, silica gel, C18 bonded silica gel, and Sephadex LH-20, followed by semi-preparative HPLC and recrystallization. The purified compounds were identified on the basis of their physicochemical properties and spectral data as macaolidine (1), tryptophan (2), daucosterol (3), (3S)-1, 2, 3, 4-tetrahydro-β-carboline-3-carboxylicacid (4), chlorogenic acid (5), luteolin (6), and hyperoside (7). Compound 1 is a new phenylacetamide alkaloid, and compounds 4-7 were isolated from Lepidium meyenii for the first time.

对云南鹤庆产黄玛咖(Lepidium meyenii Walp.)的抗骨质疏松部位进行了化学成分研究。采用MCI大孔吸附树脂、正相硅胶色谱、反相硅胶色谱、Sephadex LH-20色谱、半制备HPLC柱色谱以及重结晶等多种分离手段,从黄玛咖的正丁醇部位分离得到7个化合物,对所得单体化合物依据理化性质及波谱数据进行结构鉴定,分别为:macaolidine(1)、色氨酸(2)、胡萝卜苷(3)、(3S)-1,2,3,4-四氢-β-卡波林-3-羧酸(4)、绿原酸(5)、木犀草素(6)和金丝桃苷(7)。化合物1为一个新的酰胺类生物碱,化合物4~7均为首次从该植物中分离得到。

This study was designed to investigate the chemical constituents of the anti-osteoporotic part of Lepidium meyenii Walp. (maca) produced in Heqing, Yunnan. Seven compounds were isolated from the n-BuOH extract of maca using combination of column chromatographies on MCI resin, silica gel, C18 bonded silica gel, and Sephadex LH-20, followed by semi-preparative HPLC and recrystallization. The purified compounds were identified on the basis of their physicochemical properties and spectral data as macaolidine (1), tryptophan (2), daucosterol (3), (3S)-1, 2, 3, 4-tetrahydro-β-carboline-3-carboxylicacid (4), chlorogenic acid (5), luteolin (6), and hyperoside (7). Compound 1 is a new phenylacetamide alkaloid, and compounds 4-7 were isolated from Lepidium meyenii for the first time.

玛咖为十字花科独行菜属一年生或两年生草本植物Lepidium meyenii Walp.的根茎, 原产于秘鲁的安第斯山区, 被当地土著人用作蔬菜和保健药物。现代药理学研究证明, 玛咖具有改善性功能、提高生育能力、增强免疫力、抗疲劳、预防骨质疏松、改善更年期综合征等多种功效[1-5], 很快被国际主流社会广泛接受, 其消费量大增。因原产地的玛咖产量远远不能满足市场需求, 世界粮农组织建议推广种植玛咖, 美国、日本、欧洲等国都有引种[6]。我国也在云南、吉林、新疆、西藏等地引种了玛咖[7-10]。但目前对我国产玛咖的药理作用尚缺乏深入的研究, 其能否替代秘鲁产玛咖尚未可知, 故急需对国产玛咖进行质量评价。但玛咖的有效成分至今尚未阐明, 成为玛咖质量评价的障碍。本课题组采用活性导向的成分分离法, 研究玛咖的化学成分, 意在阐明玛咖的药效成分。
彭璐等[11]发现, 云南产玛咖的乙醇提取物对维甲酸致大鼠骨质疏松有较好的预防作用。本课题组则发现, 给维甲酸所致骨质疏松小鼠灌胃云南鹤庆产黄玛咖正丁醇提取物39.52 mg·kg-1一个月, 可明显改善模型小鼠的骨质疏松症状, 包括增加模型动物的股骨长度和股骨干重至正常对照水平, 骨磷含量也恢复至正常对照水平, 且逆转模型动物的骨显微结构破坏, 使骨小梁数量增加至接近正常水平。本文对该玛咖正丁醇萃取物进行了化学成分研究, 拟为确定玛咖的抗骨质疏松有效成分提供筛选试样, 也为评价玛咖质量提供含量测定的对照品。最终, 从鹤庆产黄玛咖的正丁醇提取物中分离得到7个化合物, 分别鉴定为macaolidine (1)、色氨酸(2)、胡萝卜苷(3)、(3S)-1, 2, 3, 4-四氢-β-卡波林-3-羧酸(4)、绿原酸(5)、木犀草素(6)和金丝桃苷(7) (图 1)。化合物1为一个新的酰胺类生物碱, 化合物4~7均为首次从该植物中分离。
化合物1    白色无定形结晶粉末。UV λmaxMeOH(nm): 250、282。IR νKBr (cm-1): 3 329、3 327、3 076、3 047、2 918、2 845、1 647、1 587、1 527、1 411.89、1 367、1 242、1 010、694; HR-ESI-MS: m/z 409.226 1 [M+H]+ (计算值409.219 5), 分子式为C23H28N4O3, 有11个不饱和度。IR光谱显示, 分子结构中存在-CONH-(3 329、3 327、1 647、1 527、1 242 cm-1), 结合1H NMR谱中的氨基氢信号δH 8.57 (1H, brs)及13C NMR谱中的羰基碳信号δC 172.4和169.8, 推测1含有两种酰胺基。1H NMR谱中的5个芳香质子信号δH 7.33~7.21 (5H, m, H-Ph), 结合13C NMR谱中的4个芳香碳信号δC 140.0、128.7、127.6、127.1, 提示该化合物含单取代苯环。根据其1H NMR谱、13C NMR谱信号数目和分子量、不饱和度, 推断该化合物为对称结构。HMBC谱(图 2)中, 亚甲基质子信号δH 4.26 (2H, d, J = 6.0 Hz)与芳碳信号δC 127.6 (C-3', 7')、140.0 (C-2')及羰基碳信号δC 172.4 (C-1) 有远程相关, 表明分子结构中有N-苄基酰胺片段。HSQC谱中, δH 1.98~1.89 (1H, m)和δH 1.89~1.81 (1H, m)均与δC 27.7相关, 表明有一个与手性C相连的-CH2-; 由HMBC谱中的相关峰δH 2.32 (2H, t, J = 7.5 Hz)/δC 27.7、δH 3.16 (1H, t, J = 6.5 Hz)/δC 27.7、δH 1.98~1.89/δC 32.5、δH 1.89~1.81/δC 32.5、δH 1.98~1.89/δC 54.2、δH 1.89~1.81/ δC 54.2, 结合HSQC相关峰δH 2.32/ δC 32.5、δH 3.16/ δC 54.2, 推断1含有-CH2-CH2-CH-片段。HMBC相关峰δH 2.32/δC 172.4提示, -CH2-CH2-CH-片段的亚甲基侧与N-苄基酰胺片段的羰基相连; δH 3.16和δC 169.8的远程相关表明, -CH2-CH2-CH-片段的次甲基侧与另一-NH-CO-的胺基相连。根据13C NMR谱中δC 172.4和δC 169.8的信号强度差异推测, 172.4 ppm处的酰胺基有2个, 而169.8 ppm处的酰胺基只有1个。分子还剩1个不饱和度, 故1还应含有1个环, 应为两个对称的-CH2-CH2-CH-片段通过次甲基相连, 构成2-咪唑烷酮。综上所述, 确定化合物1为一个新的酰胺类生物碱化合物(图 1), 命名为macaolidine。

细胞水平实验显示, 绿原酸可降低骨髓间充质干细胞来源的软骨样细胞在缺氧环境下的凋亡[17]; 且绿原酸表现出调控成骨细胞增殖和分化的能力, 通过促进骨基质的形成和钙化来促进新骨成熟, 具有一定的成骨活性[18]。Lin等[19]发现金丝桃苷通过BMP和Wnt/β-catenin信号通路共同促进成骨细胞MC3T3-E1的碱性磷酸酶的活性和细胞矿化结节的表达, 并且具有剂量依耐性。因为绿原酸(化合物5)和金丝桃苷(化合物7)在鹤庆产黄玛咖的正丁醇部位含量较高, 故依据文献推测, 绿原酸和金丝桃苷可能是鹤庆产黄玛咖的抗骨质疏松活性成分。至于黄玛咖是否还含有别的抗骨质疏松活性成分, 本实验室正拟测试本文报道的其他几个化合物对破骨细胞和成骨细胞的作用, 以期阐明玛咖抗骨质疏松的物质基础和作用机制。
