This article presents and describes Plantago humboldtiana, an extremely narrow endemic rheophytic new species from a waterfall in Corupá, Santa Catarina state, southern Brazil. The new species is unique in presenting a combination of type-G antrorse trichomes on scapes, pendulous inflorescences and 1-seeded pyxidia. Only one population is known to exist, despite intensive search efforts in near...

Prostate cancer is the most common type of diagnosed in men worldwide and second leading cause death after lung cancer. Testosterone dihydrotestosterone (DHT) have been known to play an essential role prostate Androgen receptor (AR) binding ligand allows homodimerization translocation nucleus, which acts as a transcription factor for androgen-responsive genes such PSA (Prostate-specific antigen...

Seven phenolic compounds, including a new phenylethanoid glycoside, were isolated from the ethyl acetate fraction of an aqueous ethanol extract of Plantago Herb (whole part of Plantago asiatica L.), which showed significant antioxidative activity. The new compound was characterized as 2-(3,4-dihydroxyphenyl)ethyl 3-O-β-D-allopyranosyl-6-O-caffeoyl-β-D-glucopyranoside on the basis of spectral an...

Two iridoid glucosides, catalpol and aucubin, one chlorinated iridoid aglycon, rehmaglutin D were isolated from the iridoid fraction of the aerial parts of Plantago lagopus L. together with the megastigman glucoside, phlomuroside. The structures of the isolated compounds were identified by means of spectroscopic (UV, HR-ESI, 1H-NMR, 13C NMR , HMQC, HMBC, COSY) methods. This is the first report ...
