Column temperature: 30°C; injection volume: 2 μl; flow rate: 0.25 ml/min. Mass spectrum conditions: retention time 4.94 min−1; ion pair l: quantitative ion 433.1/271.1, collision energy −22 V; ion pair 2: quantitative ion 433.1/150.9, collision energy −42 V.

Naringenin confers defence against Phytophthora nicotianae through antimicrobial activity and induction of pathogen resistance in tobacco. Mol Plant Pathol. 2022 Dec;23(12):1737-1750. doi: 10.1111/mpp.13255. Epub 2022 Sep 12. PMID: 36094814; PMCID: PMC9644278.
UHPLC
Chromatographic separation of SPLFA and SPLF was done on an Agilent 1290 UHPLC system coupled to an auto sampler, a diode array detector (DAD) and an ACQUITY UHPLC® HSS T3 column (2.1 ×100 mm, 1.8 μm; Waters, Milford, MA, USA)maintained at 30 ◦C. Eluent A was 0.05% formic acid in water and eluent B was 0.05% formic acid in acetonitrile. Elution of the SPLPA compounds was achieved using the following linear gradient elution (in %B): 0 min, 5%; 20 min, 60%; 20.1 min, 5%; 30 min, 5%, and for the SPLF compounds: 0 min, 20%, 25 min, 50%, 25.1 min, 20%, 35 min, 20%. The injection volume was 5 μL, with a flow rate of 0.3 mL/ min. All sample solutions were filtered through a 0.22 μm PTFE filter (Agilent Technologies) before analysis. The detection wavelength was 320 nm for SPLPA and 254 nm for SPLF.

HPLC-DAD
The identification and quantification of phenolics in the S. miltiorrhiza leaves extract before and after enrichment were analyzed using an Agilent 1260 Infinity LC system (Agilent Co., Palo Alto, CA, USA).10 μL of sample dissolved in 80 % methanol was injected into the HPLC system, and phenolics were chromatographed over a YMC-Pack ODS-A (250 × 4.6 mm, 5 μm) column at room temperature with a combination of 0.1 % trifluoroacetic acid (A) and acetonitrile (B) at a flow rate of 1 mL/min. The procedure for elution was as follows: 0− 5 min, 10 % B; 5− 10 min, 10 %–12 % B; 10− 20 min, 12 %–15 % B; 20− 25 min, 15 %–20 % B; 25− 60 min, 20 %–30 % B; 60− 65 min, 30 %–100 % B; 65− 70 min, 100 % B; 70− 80 min, 100 %-10 % B. Phenolics were detected by a diode array detector (DAD) at 280 nm.

UPLC-QTOT-MS
The C18 (2.1 × 100 mm, 1.7 µm) was kept at 30 ℃. The injection volume was 1 µL, and the elution was completed in 18 min with a flow rate of 0.3 mL/min. Solvents A (water + 0.1% formic acid) and B (acetonitrile) were used in the following gradients: 0–2 min (5–10% B), 2–10 min (10–20% B), 10–15 min (20–40% B), 15–17 min (40–70% B), and 17–18 min (70–100% B). The PDA spectra for phenolic compounds were measured at 320 nm and 350 nm. For MS analysis, anthocyanins were analyzed in the positive ion (PI) mode; other phenolic compounds were analyzed in the negative ion (NI) modes. The MS parameters were as follows: source temperature of 120 ℃, desolvation temperature of 250 ℃(400℃ in the positive ion), cone gas flow 50 L/h, desolvation gas flow 600 L/h (800 L/h in the positive ion), source capillary of 3.0 kV. The MS analysis was performed using mass scanning from m/z 50 to 1,500.

文献和实验的鉴定 A.水解方法：精密称取芦丁1g（±0.01g），加1%硫酸100ml，加热40min，放冷静置，过滤。所得沉淀用少许水洗除酸，干燥称重，计算苷元与糖的重量比。然后用乙醇（95%大约10ml）进行重结晶，即得苷元。 B.苷元的鉴定：用纸色谱法与对照品对照。 本实验讲解要点及注意事项 ①芦丁提取方法，重点介绍碱-酸法的原理及注意事项。 ②定性实验的目的、意义及注意事项。 ③UV及NMR光谱在芦丁结构检识中的应用。
的相关性，但并不完全相同，有时差别会很大。如英国Glaxo公司提供的头孢呋肟酯对照品，HPLC标定为96.9%，供含量测定用；UV为98.8%，供溶出度测定。虽然中国药典凡例明确规定卫生部所发对照品仅用于正文中所规定的分析方法。但由于： （1）卫生部提供的对照品使用说明书不够详尽，大多无对照品质量要求及标定方法； （2）对对照品或标准品的正确使用缺乏认识； （3）日常科研中极难找到相应的对照品； （4）中国药典正文中也常存在对照品混用的问题，如常将含量测定用的标准品或对照品用于溶出
