Four alkaloids were isolated from L., including two new compounds, 2-(4-amino-6-hydroxy-1,6-dihydropyrimidin-5-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol, named Olerapyrimidine () and (2 R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-((6-hydroxypyridin-3-yl)oxy)tetrahydro-2H-pyran-3,4,5-triol, named Olerapyridine (), and two known compounds including 1H-imidazole () and (5S, 6 R, 7S, 8 R)-5-amino-(2Z,4Z)-1,2,3-trihydroxybuta-2,4-dienyloxy-pentane-6,7,8,9-tetraol () from for the first time. Their structures were determined by spectroscopic methods, including UHPLC-ESI-Q-TOF/MS, 1D and 2D NMR spectra. Both Olerapyrimidine and Olerapyridine at 20 μM could inhibit the inflammatory factors, IL-1β and TNF-α in the RAW 264.7 cells induced by LPS.

, a genus within the Malvaceae family, is abundantly distributed in tropical and subtropical areas worldwide. Many species of this genus are widely utilized in various ways, including chewing, in folk medicine, acting as an anti-inflammatory agent, and treating gastrointestinal disorders, rheumatism, and asthma, among other conditions. These applications are largely due to their secondary metabolites, primarily quinolone alkaloids and cyclopeptides.
