Megastigmane glycosides from the traditional Uighur medicine Cydonia oblonga Mill.
Phytochemical investigation on the fruits of Cydonia oblonga Mill., a traditional Uighur medicine, led to the isolation of seven undescribed and nine known megastigmane glycosides. Their structures including absolute configurations were characterized by an extensive analysis of spectroscopic data including HRESIMS and NMR, combined with ECD calculations. Additionally, compounds 1, 2, 4, and 6–16 exhibited anti-inflammatory activity by inhibiting the secretion of cytokines TNF-α and IL-6 in RAW264.7 cells induced by lipopolysaccharides (LPS) with inhibitory rates of 10.79%–44.58% at 20 μM.
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.
