Three previously unreported diterpenoids, -gaultheric acid (), 7-hydroxy-karamatsuic acid () and -bodinieric acid J (), along with seven known diterpenoids (), were yielded from the 95% ethanol extract of the aerial parts of Vahl. The elucidation of their structure was accomplished through integrated interpretation of physicochemical characteristics combined with multi-spectral investigations, including 1D/2D NMR, ECD and HR-ESI-MS. Anti-inflammatory activity tests were conducted on the compounds -, revealing that inhibited LDH release with an IC value of 14.

Article Synopsis
- - Ten new flavonoids, called denticulains A-J, were discovered in the plant Macaranga denticulata, along with seven previously known flavonoids.
- - The structures of these compounds were determined using advanced techniques and by comparing them with existing data.
- - Two specific compounds (denticulain A and another known flavonoid) showed the ability to inhibit cancer cell growth in lab tests, with respective IC values of 46.08 μM and 56.83 μM.
