Objective:

To establish a content determination method for 14 components in pine needles of different varieties and origins simultaneously by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-QQQ MS/MS).

Methods:

The UPLC-QQQ MS/MS was adopted. A Waters ACQUITY UPLC BEH HILIC (100 mm×2.1 mm,1.7 μm) chromatographic column was used,with a column temperature of 35 ℃. The mobile phase was a mixture of 0.1% formic acid-acetonitrile solution (A) and 0.1% formic acid-aqueous solution (B) for gradient elution,with a flow rate of 0.2 mL·min-1. Electrospray ionization was used,and multiple reaction monitoring mode was employed. The monitored ion pairs of each component were m/z 125.0/79.1(gallic acid),m/z 105.1/77.2(p-hydroxybenzyl alcohol),m/z 109.1/91.1(protocatechuic acid),m/z 93.1/65.2(p-hydroxybenzoic acid),m/z 190.9/85.2(chlorogenic acid),m/z 151.8/108.2(vanillic acid),m/z 135.1/89.2(caffeic acid),m/z 167.0/122.9(syringic acid),m/z 119.2/93.2(p-coumaric acid),m/z 208.1/193.0(sinapic acid),m/z 82.0/77.2(benzoic acid),m/z 91.3/65.3(phenylacetic acid),m/z 93.1/65.2(salicylic acid),and m/z 103.2/77.2(cinnamic acid).

Results:

The content ranges of each component in the 12 determined pine needle samples were as follows:gallic acid 0.34-3.42 mg·g-1p-hydroxybenzyl alcohol 1.32-9.76 mg·g-1,protocatechuic acid 0-6.32 mg·g-1p-hydroxybenzoic acid 0-19.06 mg·g-1,chlorogenic acid 0-18.78 mg·g-1,vanillic acid 0.16-3.81 mg·g-1,caffeic acid 0-6.68 mg·g-1,syringic acid 0.09-4.64 mg·g-1p-coumaric acid 0.10-9.90 mg·g-1,sinapic acid 0.98-19.01 mg·g-1,benzoic acid 1.28-18.21 mg·g-1,phenylacetic acid 0.95-20.72 mg·g-1,salicylic acid 0-3.25 mg·g-1,and cinnamic acid 0-0.27 mg·g-1. Each component had a good linear relationship within the test range,and the average sample recovery rate was between 98.0% and 101.7%. The quantitative limits of the 14 components were between 0.01 and 0.4 ng.

Conclusion:

This method is applicable for the determination of phenolic acids in common pine needles,in which 9 compounds,including p-hydroxybenzyl alcohol,chlorogenic acid,vanillic acid,syringic acid,p-coumaric acid,sinapic acid,benzoic acid,salicylic acid,are determined for the first time in pine needles,which can provide reference for the determination of various phenolic acids in pine needles.

目的:

建立超高效液相色谱串联质谱(UPLC-QQQ MS/MS)同时测定不同品种和产地的松针中14个成分的含量测定方法。

方法:

运用UPLC-QQQ MS/MS技术,采用Waters ACQUITY UPLC BEH HILIC(100 mm×2.1 mm,1.7 μm)色谱柱,柱温35 ℃,以0.1%的甲酸-乙腈溶液(A)和0.1%的甲酸-水溶液(B)为流动相,梯度洗脱,流速0.2 mL·min-1;电喷雾离子源,多反应监测模式。各成分的监测离子对分别为m/z 125.0/79.1(没食子酸)、m/z 105.1/77.2(对羟基苯甲醇)、m/z 109.1/91.1(原儿茶酸)、m/z 93.1/65.2(对羟基苯甲酸)、m/z 190.9/85.2(绿原酸)、m/z 151.8/108.2(香草酸)、m/z 135.1/89.2(咖啡酸)、m/z 167.0/122.9(丁香酸)、m/z 119.2/93.2(对香豆酸)、m/z 208.1/193.0(芥子酸)、m/z 82.0/77.2(苯甲酸)、m/z 91.3/65.3(苯乙酸)、m/z 93.1/65.2(水杨酸)、m/z 103.2/77.2(肉桂酸)。

结果:

所测定的12份松针样品中各成分含量范围分别为没食子酸0.34~3.42 mg·g-1、对羟基苯甲醇1.32~9.76 mg·g-1、原儿茶酸0~6.32 mg·g-1、对羟基苯甲酸0~19.06 mg·g-1、绿原酸0~18.78 mg·g-1、香草酸0.16~3.81 mg·g-1、咖啡酸0~6.68 mg·g-1、丁香酸0.09~4.64 mg·g-1、对香豆酸0.10~9.90 mg·g-1、芥子酸0.98~19.01 mg·g-1、苯甲酸1.28~18.21 mg·g-1、苯乙酸0.95~20.72 mg·g-1、水杨酸0~3.25 mg·g-1、肉桂酸0~0.27 mg·g-1,各成分在测试范围内线性关系良好,平均加样回收率均在98.0%~101.7%,14个成分定量限介于0.01~0.4 ng。

结论:

本方法适用于常见松针中酚酸类成分的含量测定,其中对羟基苯甲醇、绿原酸、香草酸、丁香酸、对香豆酸、芥子酸、苯甲酸、苯乙酸、水杨酸9个成分为首次在松针中发现和测定,可为松针中多种酚酸类成分含量测定提供参考。

目的:

建立超高效液相色谱串联质谱(UPLC-QQQ MS/MS)同时测定不同品种和产地的松针中14个成分的含量测定方法。

方法:

运用UPLC-QQQ MS/MS技术,采用Waters ACQUITY UPLC BEH HILIC(100 mm×2.1 mm,1.7 μm)色谱柱,柱温35 ℃,以0.1%的甲酸-乙腈溶液(A)和0.1%的甲酸-水溶液(B)为流动相,梯度洗脱,流速0.2 mL·min-1;电喷雾离子源,多反应监测模式。各成分的监测离子对分别为m/z 125.0/79.1(没食子酸)、m/z 105.1/77.2(对羟基苯甲醇)、m/z 109.1/91.1(原儿茶酸)、m/z 93.1/65.2(对羟基苯甲酸)、m/z 190.9/85.2(绿原酸)、m/z 151.8/108.2(香草酸)、m/z 135.1/89.2(咖啡酸)、m/z 167.0/122.9(丁香酸)、m/z 119.2/93.2(对香豆酸)、m/z 208.1/193.0(芥子酸)、m/z 82.0/77.2(苯甲酸)、m/z 91.3/65.3(苯乙酸)、m/z 93.1/65.2(水杨酸)、m/z 103.2/77.2(肉桂酸)。

结果:

所测定的12份松针样品中各成分含量范围分别为没食子酸0.34~3.42 mg·g-1、对羟基苯甲醇1.32~9.76 mg·g-1、原儿茶酸0~6.32 mg·g-1、对羟基苯甲酸0~19.06 mg·g-1、绿原酸0~18.78 mg·g-1、香草酸0.16~3.81 mg·g-1、咖啡酸0~6.68 mg·g-1、丁香酸0.09~4.64 mg·g-1、对香豆酸0.10~9.90 mg·g-1、芥子酸0.98~19.01 mg·g-1、苯甲酸1.28~18.21 mg·g-1、苯乙酸0.95~20.72 mg·g-1、水杨酸0~3.25 mg·g-1、肉桂酸0~0.27 mg·g-1,各成分在测试范围内线性关系良好,平均加样回收率均在98.0%~101.7%,14个成分定量限介于0.01~0.4 ng。

结论:

本方法适用于常见松针中酚酸类成分的含量测定,其中对羟基苯甲醇、绿原酸、香草酸、丁香酸、对香豆酸、芥子酸、苯甲酸、苯乙酸、水杨酸9个成分为首次在松针中发现和测定,可为松针中多种酚酸类成分含量测定提供参考。

Objective:

To establish a content determination method for 14 components in pine needles of different varieties and origins simultaneously by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-QQQ MS/MS).

Methods:

The UPLC-QQQ MS/MS was adopted. A Waters ACQUITY UPLC BEH HILIC (100 mm×2.1 mm,1.7 μm) chromatographic column was used,with a column temperature of 35 ℃. The mobile phase was a mixture of 0.1% formic acid-acetonitrile solution (A) and 0.1% formic acid-aqueous solution (B) for gradient elution,with a flow rate of 0.2 mL·min-1. Electrospray ionization was used,and multiple reaction monitoring mode was employed. The monitored ion pairs of each component were m/z 125.0/79.1(gallic acid),m/z 105.1/77.2(p-hydroxybenzyl alcohol),m/z 109.1/91.1(protocatechuic acid),m/z 93.1/65.2(p-hydroxybenzoic acid),m/z 190.9/85.2(chlorogenic acid),m/z 151.8/108.2(vanillic acid),m/z 135.1/89.2(caffeic acid),m/z 167.0/122.9(syringic acid),m/z 119.2/93.2(p-coumaric acid),m/z 208.1/193.0(sinapic acid),m/z 82.0/77.2(benzoic acid),m/z 91.3/65.3(phenylacetic acid),m/z 93.1/65.2(salicylic acid),and m/z 103.2/77.2(cinnamic acid).

Results:

The content ranges of each component in the 12 determined pine needle samples were as follows:gallic acid 0.34-3.42 mg·g-1p-hydroxybenzyl alcohol 1.32-9.76 mg·g-1,protocatechuic acid 0-6.32 mg·g-1p-hydroxybenzoic acid 0-19.06 mg·g-1,chlorogenic acid 0-18.78 mg·g-1,vanillic acid 0.16-3.81 mg·g-1,caffeic acid 0-6.68 mg·g-1,syringic acid 0.09-4.64 mg·g-1p-coumaric acid 0.10-9.90 mg·g-1,sinapic acid 0.98-19.01 mg·g-1,benzoic acid 1.28-18.21 mg·g-1,phenylacetic acid 0.95-20.72 mg·g-1,salicylic acid 0-3.25 mg·g-1,and cinnamic acid 0-0.27 mg·g-1. Each component had a good linear relationship within the test range,and the average sample recovery rate was between 98.0% and 101.7%. The quantitative limits of the 14 components were between 0.01 and 0.4 ng.

Conclusion:

This method is applicable for the determination of phenolic acids in common pine needles,in which 9 compounds,including p-hydroxybenzyl alcohol,chlorogenic acid,vanillic acid,syringic acid,p-coumaric acid,sinapic acid,benzoic acid,salicylic acid,are determined for the first time in pine needles,which can provide reference for the determination of various phenolic acids in pine needles.

松针是松属植物的针状叶,在历史上被视为重要的药食同源天然产品。中医理论认为松针具有“祛风湿,调节内脏阴阳,轻身不饥,延年益寿”的作用[1]。现代药理研究表明,松针具有抗癌抗真菌抗关节炎降血糖降血脂抗氧化防治动物疾病等作用[2-3]。酚酸类化合物是在包括松属在内的植物中含有的天然活性物质,是主要的次生代谢产物[4]。它广泛存在于植物的各个部位,具有显著的抗氧化[5],抗炎[6]和抗微生物[7]活性。对于松针化学成分研究的报道颇多[8-10],然而对于松针中酚酸类成分的研究相对较少,关于松针抗氧化和抑菌活性的物质基础研究较多以“总酚酸”的形式呈现,其酚酸类单体成分研究不够丰富[11]。超高效液相色谱串联三重四极杆质谱(UPLC-QQQ MS/MS)技术具有高通量,重复性好,适合定量分析等特点,目前用于定性、定量分析已较为普及,是含量测定研究的常用技术[12-13],适合用于解决酚酸类成分在松针中含量差异大且易产生干扰等分析困难。本文在前期对松针酚酸类成分单体分离、鉴定的基础上,参考了相关文献[14-16],运用UPLC-QQQ MS/MS法,进行酚酸类成分的含量表征方法的研究,为该类成分进一步精准研究和开发提供参考。

本研究考查了纯水、纯甲醇、30%甲醇溶液、50%甲醇溶液、70%甲醇溶液以及纯乙醇、50%乙醇溶液的提取效果,发现纯水不能完全提取出所测成分,特别是苯乙酸、水杨酸等成分影响较大;纯水、纯甲醇、30%甲醇中多糖等水溶性杂质较高,影响待测成分的分离,除杂效果不佳;70%甲醇溶液以及纯乙醇、50%乙醇溶液提取液中杂质较高,可能与树脂含量增高有关,这造成基线在后半段分析时间内漂移较大;综合考虑,发现50%甲醇作为溶剂超声提取液所测的图谱分离度较好,基线平稳,能够较好的满足分析需要,故采用50%甲醇作为提取溶剂。另外,实验中考查了Waters ACQUITY UPLC HSS C18 (100 mm×2.1 mm,1.8 μm)、Waters ACQUITY UPLC BEH HILIC(100 mm×2.1 mm,1.7 μm)和Agilent Eclipse Plus C18 RRHD(150 mm×2.1 mm,1.8 μm)色谱柱对样品的分离表现,发现Agilent Eclipse Plus C18 RRHD (150 mm×2.1 mm,1.8 μm)柱测得的酚酸色谱峰对称性不佳,拖尾明显,Waters ACQUITY UPLC HSS C18 (100 mm×2.1 mm,1.8 μm)柱所测的各成分保留时间不稳定,受流动相中甲酸含量影响较明显,相对而言,Waters ACQUITY UPLC BEH HILIC(100 mm×2.1 mm,1.7 μm)柱对所测成分的分离效果理想、对称性好,适合较多酚酸成分的同时测定需要,故采用Waters ACQUITY UPLC BEN HILIC(100 mm×2.1 mm,1.7 μm)柱进行分析。
通过提取、分离、纯化、结构鉴定等工作,首先在雪松松针中得到了文中所述的14个单体化合物,后续研究发现,这些成分普遍存在于各种松针中。其中对羟基苯甲醇、绿原酸、香草酸、丁香酸、对香豆酸、芥子酸、苯甲酸、苯乙酸、水杨酸等9个物质是在松针中首次分离、和测定。这些成分以酚酸类成分为主,可能是松针发挥抗氧化和抑菌活性的部分物质基础,同时可能也是松针化感作用和胃肠道刺激作用的主要来源。因此本研究对于未来松针精准、科学的应用具有一定的参考价值。
松针作为能够抑菌和抗氧化的天然产物,在医疗保健以及食品保鲜方面广泛应用,这与其所含的酚酸类成分密切相关,所测定的松针中各酚酸类成分含量差异较为明显,6种松针中,白皮松测得的总酚酸含量最低(<26 mg·g-1),而华山松中测得的总酚酸含量最高(>43 mg·g-1);与其他品种的松针相比,落叶松以水杨酸含量最高,咖啡酸含量较低为特征;油松松针以绿原酸、咖啡酸含量最高为特征;樟子松松针以苯甲酸含量最高为特征;华山松松针以对香豆酸含量最高为特征,雪松松针以苯乙酸含量最高、咖啡酸含量最低为特征;以上特征与松针的来源有关,同品种的松针因产地不同,在成分上亦产生较大差别,说明生长环境对植物的次生代谢产物含量影响同样重要;另外,对雪松、白皮松、华山松不同生长年限次生代谢产生的酚酸类成分含量与其抑菌活性的关系进行考察,发现松针抑菌活性与酚酸的含量有关,但同时受其他因素影响,考虑到这不是本文重点讨论的内容,因此另作讨论。目前虽不能将植物种酚酸类成分的差异与生物学活性之间的联系完全阐明,然而,本文对不同松针酚酸类成分化学轮廓的描述以及未来谱效关系的建立仍具有参考价值。
作者曾用HPLC法对文中所述的14个成分进行测定,除检测波长需要按照不同成分最大吸收波长进行切换外,还需要对所测成分进一步富集,所建立的色谱条件基本与文中所述的色谱方法相同,同样能测定松针中的以上成分;然而,由于个别成分在松针中含量不高,一些酚酸峰面积相差几百倍,加之各成分检测波长相差较大,导致色谱图中这些峰的识别不够直观,含量很低的成分积分误差较为明显,检测限的建立相对困难;若采用测波长切换技术则限制了多数品牌HPLC之间的通用性,且较为烦琐;故使用液质联用技术对这些成分进一步分析研究,这样可以较好地解决前述问题。
