Article Synopsis
  • - Phyllanthi Fructus (PF) has a history of use for its strong antioxidant and anti-inflammatory properties, mainly due to its high polyphenol content, but current extraction methods limit its potential.
  • - This study used ultrasonic-assisted extraction (UAE) to enhance polyphenol yields and antioxidant activity in PF, employing techniques like Plackett-Burman designs (PBD) and response surface methodology (RSM) to optimize the extraction process.
  • - Results showed an optimized polyphenol yield of 213.49 mg/g and significant antioxidant activities, with 26 polyphenol components identified, including ellagic acid and myricetin, which may interact with proteins like AKT1 to exert antioxidant

RSA-1 is a polysaccharide obtained from Raphani semen with a relatively clear structure and anti-colon cancer activity. In this study, high-performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), and nuclear magnetic resonance (NMR) spectroscopy were applied to characterise the complex chain structure of RSA-1. Subsequently, the inhibitory effect on colon cancer growth through apoptosis induction in colon cancer cells was explored.

(Gouteng in Chinese, GT) is the main medicine in many traditional recipes in China. It is commonly used to alleviate central nervous system (CNS) disorders, although its mechanism in Alzheimer's disease is still unknown. This study was designed to predict and validate the underlying mechanism in AD treatment, thus illustrating the biological mechanisms of GT in treating AD.

In this study, we developed an ultra-performance liquid chromatography-electrospray tandem quadrupole mass spectrometry (UHPLC-ESI-MS/MS) method to simultaneously determine Picroside-I, Picroside-II, Picroside-III, minecoside, and sweroside in rat plasma. The chromatographic column was an ACQUITY UHPLC BEH Amide Column (2.1 × 100 mm, 1.
