A systematic phytochemical investigation of Polygonatum cyrtonema Hua. processed by nine cycles of steaming and sun-drying was carried out using silica gel, Toyopearl HW-40C, octadecylsilyl (ODS) silica gel, and semi-preparative HPLC, leading to the isolation of three nitrogen-containing compounds. The structures of the isolates were elucidated by comprehensive spectroscopic analyses, including HRESIMS, NMR, IR, and UV, and were identified as cyrtoneine F (1), (2S,5S)-5-[(1S)-1-methylpropyl]-3,6-dioxo-2-piperazine propanoic acid (2), (2S,5S)-5-(2-methylpropyl)-3,6-dioxo-2-piperazine propanoic acid (3). Compound 1 was characterized as a new amide, whereas compounds 2 and 3 were determined to be diketopiperazines, which were isolated for the first time from Polygonatum cyrtonema Hua.

采用硅胶、Toyopearl HW-40C、ODS以及半制备液相等方法和技术对九蒸九晒多花黄精进行系统地化学成分研究, 分离得到3个含氮类化合物。通过HRESIMS、NMR、IR、UV等波谱学方法进行结构鉴定, 分别鉴定为多花黄精碱F (1), (2S,5S)-5-[(1S)-1-methylpropyl]-3,6-dioxo-2-piperazine propanoic acid (2), (2S,5S)-5-(2-methylpropyl)-3,6-dioxo-2-piperazine propanoic acid (3)。其中化合物1为新的酰胺类化合物, 化合物2和3为二酮哌嗪类化合物且为首次从多花黄精中分离得到。

A systematic phytochemical investigation of Polygonatum cyrtonema Hua. processed by nine cycles of steaming and sun-drying was carried out using silica gel, Toyopearl HW-40C, octadecylsilyl (ODS) silica gel, and semi-preparative HPLC, leading to the isolation of three nitrogen-containing compounds. The structures of the isolates were elucidated by comprehensive spectroscopic analyses, including HRESIMS, NMR, IR, and UV, and were identified as cyrtoneine F (1), (2S,5S)-5-[(1S)-1-methylpropyl]-3,6-dioxo-2-piperazine propanoic acid (2), (2S,5S)-5-(2-methylpropyl)-3,6-dioxo-2-piperazine propanoic acid (3). Compound 1 was characterized as a new amide, whereas compounds 2 and 3 were determined to be diketopiperazines, which were isolated for the first time from Polygonatum cyrtonema Hua.

多花黄精(Polygonatum cyrtonema Hua.)为百合科黄精属植物, 与黄精(Polygonatum sibiricum Red.)、滇黄精(Polygonatum kingianum Coll. et Hemsl.)共同作为黄精(Polygonati Rhizoma)使用。据中国药典(2025年版)记载, 其具有补气养阴、健脾、润肺、益肾之功效, 临床上用于治疗脾胃气虚、肺虚燥咳、精血不足、早发白发、内热消渴、潮热盗汗等证[1]。此外, 黄精作为86味药食两用中药之一, 亦可制作为黄精酒、黄精功能饮料、黄精药渣蛋白饲料等相关产品, 具有抗氧化、抗疲劳等功效[2]。黄精生食具有麻舌感且刺人咽喉, 需炮制后入药, 传统炮制工艺包括九蒸九制法、酒制法、蜜制法等[3]。据文献报道, 黄精中含有多糖[4]、皂苷[5]、黄酮、生物碱[6]、氨基酸等多种化学成分, 具有抗肿瘤[7]、抗氧化[8]、抗疲劳、提高免疫力、降血糖、降血压、降血脂、保护神经、抗病毒等药理作用[9]。为阐明其发挥药效的物质基础, 并提升该药用植物的资源开发价值, 本研究对九蒸九晒多花黄精的70%丙酮提取物进行系统的分离纯化, 得到3个新化合物, 包括1个酰胺类和2个二酮哌嗪类化合物。

实验用九蒸九晒多花黄精药材由郑州瑞龙制药股份有限公司于2024年5月提供(批号: E230701), 药材标本保存于河南中医药大学药学院中药化学实验室。
九蒸九晒多花黄精40 kg, 使用70%丙酮组织破碎提取两次, 合并提取液, 减压浓缩得到总浸膏(14.24 kg), 总浸膏加水分散后经大孔吸附树脂柱色谱, 依次使用水、10%乙醇、20%乙醇、30%乙醇、50%乙醇进行梯度洗脱, 依次得到各个洗脱部位。10%乙醇部位(162.21 g)经MCI柱色谱, 使用甲醇-水(0∶100~100∶0)进行梯度洗脱, 得到7个洗脱部位10-1~10-7。10-3 (34.78 g)经ODS柱色谱, 使用甲醇-水(10∶90~30∶70)进行梯度洗脱, 得到2个洗脱部位10-3-1和10-3-2。10-3-1 (4.03 g)经Toyopearl HW-40C柱色谱, 使用甲醇-水(0∶100~50∶50)进行梯度洗脱, 得到2个组分10-3-1-1和10-3-1-2。组分10-3-1-1 (1.24 g)经半制备高效液相(甲醇-水, 20∶80)等度洗脱, 得到4个组分10-3-1-1-1~10-3-1-1-4。组分10-3-1-1-2 (59.07 mg)再次经半制备高效液相(甲醇-水, 15∶85)等度洗脱, 得到化合物1 (7.26 mg, tR = 34.37 min)。组分10-3-1-1-3 (47.91 mg)经半制备高效液相(甲醇-水, 18∶82)等度洗脱, 得到化合物2 (11.43 mg, tR = 35.87 min)。组分10-3-1-1-4 (57.98 mg)经半制备高效液相(甲醇-水, 18∶82)等度洗脱, 得到化合物3 (11.69 mg, tR = 43.62 min)。
称取化合物各1.0 mg, 加入6 mol L-1盐酸水溶液3 mL, 于115 ℃加热水解2 h。反应液冷却至室温后, 加水并减压浓缩, 该操作重复3次以除去残留的盐酸。浓缩干燥后, 加入1 mol L-1 NaHCO3水溶液100 μL溶解样品, 再加入10 mg mL-1 L-FDAA丙酮溶液50 μL, 于80 ℃水浴加热3 min。随后加入2 mol L-1盐酸水溶液50 μL淬灭反应。最后, 加入1.3 mL 50%乙腈水溶液稀释混合物, 备用。D-异亮氨酸、L-异亮氨酸、D-亮氨酸、L-亮氨酸、D-谷氨酸、L-谷氨酸标准品按照上述衍生方法衍生得到对照品。由于化合物1经酸水解后得到甘氨酸、异亮氨酸、谷氨酸, 而甘氨酸无手性, 故无甘氨酸对照品。通过高效液相色谱仪分析衍生产物, 色谱条件: Symmetry C18 (250 mm × 4.6 mm, 5 μm), 流动相为乙腈-水(10∶90~100∶0, 30 min, 水中含有0.1%的甲酸), 流速为1.0 mL min-1。通过与对照品保留时间对比, 确定化合物1中的氨基酸为L-异亮氨酸、L-焦谷氨酸(图3), 化合物2中的氨基酸为L-异亮氨酸、L-谷氨酸, 化合物3中的氨基酸为L-亮氨酸、L-谷氨酸。
多花黄精为中药材黄精中的上品, 为药食两用中药材之一。九蒸九晒为传统炮制工艺, 经炮制后, 其药性趋于温润, 可减轻不良反应并增强补益之功。本研究对九蒸九晒多花黄精70%含水丙酮提取物进行系统的分离纯化, 得到3个化合物, 包括1个新的酰胺类化合物和2个二酮哌嗪类化合物。丰富了九蒸九晒多花黄精的化学成分, 为其开发利用奠定物质基础。
