A comprehensive pharmacokinetic strategy for systematic evaluation of whole interaction of different constituents in Astragali Radix -Fructus Corni to improve diabetic kidney disease.

Ethnopharmacological Relevance: Astragali-Radix (the dried root of Astragalus mongholicus Bunge, AR) - Fructus Corni (the dried ripe fruit of Cornus officinalis Sieb. et Zucc., FC) has been used as a herb-pair remedy to treat diabetic kidney disease (DKD) for hundred years.

Phytochemical component profiling and anti-renal fibrosis effects of crude and salt-stir fried Eucommiae Cortex extracts on renal fibrosis rats caused by high-purine diet.

A prolonged diet laden with purine-rich foods represents a significant contributor to renal fibrosis (RF). Eucommia ulmoides Oliver, a plant homologous to food and medicinal materials, has long been employed to recover kidney function. This investigation presents a strategy integrating chemistry, biochemistry, and metabolomics to evaluate bioactive components and efficiency mechanism of crude and salt-stir fried Eucommiae Cortex (EC) extracts against RF.

[Effect of compatibility of Corni Fructus before and after wine-processing with Astragali Radix on plasma metabolomics in diabetic nephropathy rats based on UHPLC-Q-TOF-MS/MS].

Based on the processing and compatibility, this study explored the effects of components in Corni Fructus(CF) and Astragali Radix(AR) on plasma metabolomics in diabetic nephropathy rats. SD rats were randomly divided into four groups and diabetic nephropathy rat model was induced by high-fat diet combined with 30 mg·kg~(-1) streptozotocin(STZ). Histopathological observations of kidney tissue sections of rats in each group were conducted using HE, PAS, and Masson staining.
