A quantitative H-NMR method (H-qNMR) was developed to determine the concentration of acteoside and geniposidic acid in Plantaginis semen, which is an important crude drug for diuretic purposes. The purity of geniposidic acid and acteoside was determined by the ratio of the intensity of the H-3 signal at δ 7.51 ppm or the H-7″ signal at δ 7.58 ppm in methanol-d to that of a hexamethyldisilane (HMD) signal at 0.04 ppm, respectively. The concentration of HMD was corrected with the International System of Units traceability using potassium hydrogen phthalate of certified reference material grade. The geniposidic acid content in two batches of Plantaginis semen as determined by H-qNMR was found to be 0.84 and 1.00 %, and the acteoside content was determined to be 0.80 and 0.93 %. We demonstrated that this method is useful for the quantitative analysis of geniposidic acid and acteoside in Plantainis semen.

Oxidative stress is a key factor that activates several transcription factors and mediators involved in the inflammatory pathways responsible for the pathogenesis of many chronic diseases. Targeting the expression of these mediators represents a promising approach to preventing these diseases. leaf infusion is traditionally used for treating conditions such as inflammation and pain relief.

Renal fibrosis is an outcome of chronic kidney disease, independent of the underlying etiology. Renal fibrosis is caused primarily by oxidative stress and inflammation. We identified the components of Plantaginis semen and elucidated their anti-fibrotic and anti-inflammatory mechanisms.

Introduction: Fructus Gardeniae (ZZ), a traditional Chinese herb, has been used in treating patients with jaundice, inflammation, etc. When mixed with ginger juice and stir-baked, ginger juice-processed Fructus Gardeniae (JZZ) is produced, and the chemical compositions in ZZ would be changed by adding the ginger juice.
Objective: To illuminate the differential components between ZZ and JZZ.
