Optimization of Ultrasound-Assisted Extraction of Leaves: Maximal Phenolic Yield and Antioxidant Capacity.

() is a medicinal plant with secondary metabolites such as phenolics, flavonoids, glycosides, saponins, and alkaloids. This study was designed to optimize the ultrasonic-assisted extraction (UAE) parameters to enhance the phenolic content and characterize the phenolic compounds using ultra-high-performance liquid chromatography, coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (UHPLC-ESI-QTOF-MS/MS), and antioxidant activities in extract. Extraction time, sample-to-solvent ratio, and extraction temperature were considered for UAE optimization.

Feeding Practice During a Diarrheal Episode and Associated Factors Among Mothers/Caregivers with 6-59-Month-Old Children Visiting Health Centers in Shanan Dhuggo District, West Hararge Zone, Oromia Region, Ethiopia.

Background: Continued feeding and increasing fluids is the cornerstone treatment package for a child with acute diarrhea. However, there is a deficiency of evidence on child feeding practice during a diarrheal episode globally and particularly in low-income countries. This study aimed at assessing feeding practice during diarrheal episodes and associated factors among mothers/caregivers with 6-59-month-old children visiting health centers in Shanan Dhuggo district, West Hararge zone, Oromia region, Ethiopia.
