Abstract
Seven undescribed iridoids, identified as valeriridoids A-E (compounds 1, 5, 18, 19a, 19b, 20a, and 20b), were isolated from the roots and rhizomes of Valeriana officinalis L., along with sixteen known iridoids and nine known lignans. The structures were elucidated using NMR and MS spectroscopy, and the absolute configurations of the undescribed iridoids were determined through ECD calculations. Valeriridoids D and E were found to be epimeric and scalemic mixtures, which were successfully resolved through a chiral column. These isolated iridoids were evaluated for their antiproliferative activities, with valeriridoid A, jatamanvaltrates P, and Q showing significant effects against human non-small cell lung cancer cells, with IC50 values of 14.68, 8.77, and 10.07 μM, respectively. Furthermore, the antihyperglycemic properties of the compounds were investigated in insulin-resistant human hepatoblastoma cells induced by palmitic acid treatment, revealing that valeriridoid A, jatamanvaltrates P, and Q at a concentration of 10 μM led to a notable increase in glucose consumption.
期刊介绍:
Phytochemistry is a leading international journal publishing studies of plant chemistry, biochemistry, molecular biology and genetics, structure and bioactivities of phytochemicals, including ''-omics'' and bioinformatics/computational biology approaches. Phytochemistry is a primary source for papers dealing with phytochemicals, especially reports concerning their biosynthesis, regulation, and biological properties both in planta and as bioactive principles. Articles are published online as soon as possible as Articles-in-Press and in 12 volumes per year. Occasional topic-focussed special issues are published composed of papers from invited authors.
