YWG

Methods The chromatographic conditions included a column YWG C18, mobile phase: methanol-water ( 50 ∶ 50), adjusting to pH 3.0 by 0.3% triethylamine solution and phosphoric acid, flow rate 1 ml/ min, and wavelength 230 nm.

流动相为甲醇-水（50∶50，含0.3%三乙胺，磷酸调pH3.0）；流速1ml/min；

METHODS: HPLC, colume: YWG C 18 ( 4.6mm × 250mm, 5 μ m), mobile phase: methanol 0.25% phosphoric acid ( 80 ∶ 20), wavelength: 436nm, flow rate: 1.1ml/ min, column temperature: room temperature.

方法：用高效液相法测定，选定YWG C18分析柱（4.6mm×250mm，5μm），流动相：甲醇0.25%磷酸（80∶20），检测波长：436nm，流速：1.1ml/min，柱温：室温。

Conclusion: YWG can protect the gastric mucosa and repair its damage by regulating the secretion of gastrointestinal hormone.
