Exploration and evaluation of antioxidant activity in isolated phenolics from (retz) vahl.

Given the widespread and established use of (Retz) Vahl, a member of the Oleacea family, this study aimed to identify and characterise secondary metabolites derived from the plant, with the objective of evaluating their potential biological activities. Using chromatographic separations techniques based on molecular weight and polarity, various VLC fractions of the plant were purified. These fractions yielded seven compounds- 2-(4-hydroxyphenyl)-ethanol , 2-(4-hydroxy-3-methoxy-phenyl)-ethanol , 1-(4-hydroxy-3-methoxy-phenyl)-1,2,3-propanetriol , 1-(4-hydroxy-3,5-dimethoxy-phenyl)-1,2,3-propanetriol , lupeol , β-sitosterol , and methyl linoleate , which have never been previously reported in this plant.

Cryopreservation of Bangladeshi ram semen using different diluents and manual freezing techniques.

A study was conducted to establish a sustainable and effective manual freezing technique for cryopreservation of Bangladeshi ram semen. Three diluents and freezing techniques were tested, both as treatment combinations (diluent × freezing technique) and fixed effects (diluent or freezing technique) on post-thaw sperm motility (SM), viability (SV), plasma membrane integrity (SPMI) and acrosome integrity (SAI). Ten rams were selected, based on semen evaluation.
