ABSTRACT
Phytochemical investigation of the fruits of Rosa roxburghii resulted in the isolation of four organic acid derivatives and three phenylpropanoids, including a new organic acid derivative, Roxbuacidester A (1) and six known compounds (2-7). The structures of all isolates were established by 1D and 2D NMR spectra referring to the literatures, together with HR-MS spectrometric analysis. In addition, compounds 1 and 2 were evaluated for their inhibitory activities on nitric oxide (NO) production stimulated by lipopolysaccharide (LPS) in a RAW 264.7 cell line. Compounds 1 and 2 showed moderate inhibition of NO production with IC50 values of 46.8 ± 2.3 and 62.5 ± 3.7 μM, respectively.
