OBJECTIVE To investigate the terpenoid constituents from the fresh-used leaves of Artemisia argyi Levl. et Vant. and their anti-inflammatory activities. METHODS Modern phytochemical separation techniques such as high performance preparative liquid chromatography (HPLC) were used to isolate the 95% ethanol extract of the fresh leaves from A. argyi and to identify the structure by combining physicochemical properties with MS and NMR data. The anti-inflammatory activity of terpenoids was evaluated by the inhibitory ability of nitric oxide (NO) release from LPS-induced RAW264.7 macrophages. RESULTS Fifteen terpenoids were isolated from the fresh leaves of A. argyi and identified as artanomaloide (1), dehydroleucodin (2), tamaulipin-B acetate (3), moxartenolide (4), yomogin (5), costic acid (6), costic acid methyl ester(7), PBI(8), (-)-3-hydroxy-β-ionone(9), pubinernoid A(10), subamone(11), artefrigin(12), cassipourol(13), 3β-acetoxy-24-oxo-dammara-20, 25-diene (14), dammara-20,24-dien-3β-ol acetate (15). The IC50 values of the anti-inflammatory activity of compounds 1-12 ranged from (1.27±0.02) to (17.55±0.13) μmol·L-1. CONCLUSION The fresh leaves from A. argyi are more abundant in terpenoids with anti-inflammatory activity, among which compounds 3 and 7-14 are isolated for the first time, and this kind of components can be applied in the development of pharmaceutical and health products.

目的 研究新鲜艾叶(Artemisia argyi Levi. et Vant.)中萜类成分及其抗炎效果。方法 利用高效制备液相色谱等现代植物化学分离技术对新鲜艾叶体积分数95%乙醇提取物进行分离,结合理化性质与质谱法(MS)、核磁共振谱法(NMR)等数据鉴定结构。以脂多糖(LPS)诱导RAW264.7巨噬细胞释放一氧化氮(NO)抑制能力评价萜类物质的抗炎能力。结果 共分离15个萜类物质:artanomaloide(1)、dehydroleucodin(2)、tamaulipin-B acetate(3)、莫沙坦内酯(4)、yomogin(5)、木香酸(6)、costic acid methyl ester(7)、PBI(8)、(-)-3-hydroxy-β-ionone(9)、pubinernoid A(10)、subamone(11)、artefrigin(12)、cassipourol(13)、3β-acetoxy-24-oxo-dammara-20,25-diene(14)、dammara-20,24-dien-3β-ol acetate(15),其中化合物1~12抗炎活性IC50值介于(1.27±0.02)~(17.55±0.13) μmol·L-1结论 鲜用艾叶中含有较为丰富的、具有明显抗炎活性的萜类物质,其中化合物3、7~14均为首次从艾叶中分离,该类成分有进一步在医药大健康产品中开发应用的潜能。

目的 研究新鲜艾叶(Artemisia argyi Levi. et Vant.)中萜类成分及其抗炎效果。方法 利用高效制备液相色谱等现代植物化学分离技术对新鲜艾叶体积分数95%乙醇提取物进行分离,结合理化性质与质谱法(MS)、核磁共振谱法(NMR)等数据鉴定结构。以脂多糖(LPS)诱导RAW264.7巨噬细胞释放一氧化氮(NO)抑制能力评价萜类物质的抗炎能力。结果 共分离15个萜类物质:artanomaloide(1)、dehydroleucodin(2)、tamaulipin-B acetate(3)、莫沙坦内酯(4)、yomogin(5)、木香酸(6)、costic acid methyl ester(7)、PBI(8)、(-)-3-hydroxy-β-ionone(9)、pubinernoid A(10)、subamone(11)、artefrigin(12)、cassipourol(13)、3β-acetoxy-24-oxo-dammara-20,25-diene(14)、dammara-20,24-dien-3β-ol acetate(15),其中化合物1~12抗炎活性IC50值介于(1.27±0.02)~(17.55±0.13) μmol·L-1结论 鲜用艾叶中含有较为丰富的、具有明显抗炎活性的萜类物质,其中化合物3、7~14均为首次从艾叶中分离,该类成分有进一步在医药大健康产品中开发应用的潜能。

OBJECTIVE To investigate the terpenoid constituents from the fresh-used leaves of Artemisia argyi Levl. et Vant. and their anti-inflammatory activities. METHODS Modern phytochemical separation techniques such as high performance preparative liquid chromatography (HPLC) were used to isolate the 95% ethanol extract of the fresh leaves from A. argyi and to identify the structure by combining physicochemical properties with MS and NMR data. The anti-inflammatory activity of terpenoids was evaluated by the inhibitory ability of nitric oxide (NO) release from LPS-induced RAW264.7 macrophages. RESULTS Fifteen terpenoids were isolated from the fresh leaves of A. argyi and identified as artanomaloide (1), dehydroleucodin (2), tamaulipin-B acetate (3), moxartenolide (4), yomogin (5), costic acid (6), costic acid methyl ester(7), PBI(8), (-)-3-hydroxy-β-ionone(9), pubinernoid A(10), subamone(11), artefrigin(12), cassipourol(13), 3β-acetoxy-24-oxo-dammara-20, 25-diene (14), dammara-20,24-dien-3β-ol acetate (15). The IC50 values of the anti-inflammatory activity of compounds 1-12 ranged from (1.27±0.02) to (17.55±0.13) μmol·L-1. CONCLUSION The fresh leaves from A. argyi are more abundant in terpenoids with anti-inflammatory activity, among which compounds 3 and 7-14 are isolated for the first time, and this kind of components can be applied in the development of pharmaceutical and health products.

艾叶(Artemisia argyi Levl. et Vant.),菊科多年生草本植物,广布全国[1]。作为我国传统中药,苗、布依、土家、傣等民族习用药,具有温经止血,散寒止痛,主要用于治疗吐血,衄血,崩漏,少腹冷痛,经寒不调,宫冷不孕等症[2]。鲜用艾叶始载《名医别录》用于止血、杀虫[3], 随后《本草纲目》等载其捣汁用于咽喉肿痛[4];土家、布依、傣族鲜煎水服用于咽喉痛、慢性支气管炎等[5]。现代研究主要针对陈艾或干品开展,主要含有黄酮、挥发油、萜类等化学成分,在抗炎、抗氧化、抗病毒、抗菌等方面呈现出一定优势[6];其中抗炎活性物质以挥发油为主,Reinhardt等[7]发现艾叶中倍半萜内酯可通过抑制T细胞活性达到抗炎作用,Meng等[8]揭示了鲜艾对于神经性皮炎具有很好的治疗效果。鉴于艾叶悠久的鲜用史,以及现有研究未能较好支撑艾叶鲜用的现状,本研究开展了新鲜艾叶的化学成分研究,从中获得15个萜类成分:artanomaloide(1)、dehydroleucodin(2)、tamaulipin-B acetate(3)、moxartenolide(4)、yomogin(5)、costic acid(6)、costic acid methyl ester(7)、PBI(8)、(-)-3-hydroxy-β-ionone(9)、pubinernoid A(10)、subamone(11)、artefrigin(12)、cassipourol(13)、3β-acetoxy-24-oxo-dammara-20,25-diene(14)、dammara-20,24-dien-3β-ol acetate(15);其中化合物3、7~14均为首次从艾叶中分离,化合物1~12具有明显的抗炎活性,可在医药健康产品开发中加以利用。

利用LPS诱导RAW 264.7细胞构建炎症模型,Griess 法测定细胞NO释放量[24-25]。将RAW 264.7巨噬细胞培养并配成细胞悬液,以每毫升2×105个接种于96孔板中,每孔80 μL,37 ℃、5% CO2培养箱内培育24 h。细胞按空白、模型、样品、 阳性对照[地塞米松(DX)]进行分组,样品组浓度分别为0.5、1.0、5.0、10.0、20.0 μmol·L-1,各浓度设复孔3个。除空白外,各组加 LPS 刺激(5.0 μg·mL-1),继续培养24 h,取细胞上清液50 μL,每孔依次加 Griess Ⅰ、Griess Ⅱ试剂各50 μL,混匀后于540 nm波长测定吸光度,计算NO浓度,结果见表1。由表1可知,化合物1~12表现出明显的抗炎活性,IC50值介于(1.27±0.02)~(17.55±0.13) μmol·L-1,其作用与阳性对照DX相当,是鲜艾叶主要的非挥发性抗炎物质,这些非挥发性物质可在后续抗炎产品开发中与其挥发油搭配使用,亦可作为候选先导分子进一步加以甄选。
挥发油提取是鲜用艾叶的重要形式,以桉叶素、樟脑、龙脑、松油醇、石竹烯等为主的萜类成分是其物质基础,在医药大健康产业中得到广泛应用[6]。然而在挥发油应用中,非挥发性萜类往往被忽略,倍半萜类物质作为蒿属(Artemisia L.)植物的重要特征性成分,具有多种生物活性,具有较好的应用前景[26]。本研究针对鲜用艾叶中化学成分进行研究,从中分离得到15个萜类成分,其中化合物3、7~14均为首次从艾叶中分离;通过LPS诱导RAW 264.7细胞炎症模型对所有化合物进行活性筛选,初步揭示了鲜艾叶非挥发性抗炎活性物质是以倍半萜类为主的萜类成分。为更好发挥鲜艾叶的药用价值,在今后的抗炎产品应用中,可考虑合理提取非挥发性萜类成分搭配挥发油进行使用,既能更好地增强抗炎效果,又可减少资源浪费。
