Effects of algerian nettle ( < em > Urtica dioica < /em > L.) on benign prostatic hyperplasia and their mechanism of action elucidation: in vivo and in silico approaches
This study investigated the effect of Urtica dioica roots etheric extract (UDEE) on oxidative stress, and urine obstruction with histopathological examinations of prostatic and renal tissues,and suggests computational methods as a complementary method, to make a hypothesis on the overall effect of UDEE in the treatment of benign prostatic hyperplasia (BPH).Gas chromatography/mass spectrometry was utilised to characterise UDEE.BPH was induced in rats through daily subcutaneous injections of testosterone propionate. Rats were also orally administered UDEE or a vehicle. After four weeks, prostate weight, urine output, and bio...

Nat Prod Res. 2023 Oct 22:1-10. doi: 10.1080/14786419.2023.2272288. Online ahead of print.ABSTRACTSalacia debilis Walp., (Celastraceae) is used traditionally in West Africa for the treatment of malaria. However, no scientific reports validating these effects and its active constituents are on record. Therefore, this study is aimed at evaluating the antimalarial effects, of its ethanolic extract and isolated compounds against Plasmodium falciparum 3D7 and P. berghei ANKA strains. Using chromatographic, spectrometric and spectroscopic techniques three compounds were isolated and characterised. The extract of S. debilis was a...
