Abstract: Two new together with 32 known compounds were isolated from the leaves of Lycium barbarum. Their structures were elucidated using 1D and 2D NMR, HRESIMS, and ECD spectroscopic techniques. Compounds 1–34 were evaluated for their anti-rheumatoid arthritis activities in a lipopolysaccharide (LPS)-induced MH7A cells inflammatory model. As a result, compounds 1–3, 6, 8, 10, 14, 17–19, 29 and 31 inhibited the activity of lactate dehydrogenase (LDH) and nitric oxide (NO) at concentrations 20 μM. Among them, compound 1 showed the best effectiveness, with inhibition rates of 46.7% for NO and 32.8% for LDH.
