Peoniflorin (PF) and albiflorin (AF) are two principal components of Paeonia species, which exhibit various biological activities such as improvement of blood circulation and immunoregulating function. To further utilization of waste parts of peony plants, an efficient method for preparative purification of these two ingredients from white peony ...

Abstract Ginsenoside-Ro which belongs to the oleanane-type saponins has anti-inflammatory, anti-platelet, anticomplementary and immunomodulatory activities. The present paper described the preparation of ginsenoside-Ro from panax ginseng with high recovery and efficiency by combination of normal-phase medium-pressure liquid chromatography (NP-MPLC ...

ABSTRACTIntroductionLignans and flavonols are the primary constituents of Sinopodophyllum emodi and have been used as cathartic, anthelmintic, chemotherapeutic and anti‐hypertensive compounds. Although these compounds have been isolated, there have been no reports on the separation of 4′‐demethyl podophyllotoxin, podophyllotoxin, deoxypodophyllotoxin ...

Defatted seed meals, the byproducts of Indian mustard seed oil industry, which are just used as animal feedstock and nitrogen fertilizers, possess various nutrients and phytochemical compounds, such as sinigrin and gluconapin. The present study demonstrated a novel, low-cost, and efficient method for the co-production of sinigrin and gluconapin from ...

A novel method for separation and on-line characterization of flavonoids from Asparagus officinalis by medium-pressure liquid chromatography coupled to electrospray ionization multi-stage mass spectrometry (MPLC-ESI-MSn) was successfully established. The hyphenation between MPLC and ESI-MSn was designed to keep the split ratio exactly in the range from
