This is the first chemical study of Sarcomelicope follicularis, a species endemic to New Caledonia. The stem barks were dried and powdered, then extracted successively with cyclohexane and methylene chloride. GC-MS analysis was performed using an Agilent 6890 gas chromatograph coupled with a Hewlett Packard 5973 Mass Selective Detector, with compound identification based on mass spectral data (Wiley 275, NIST 98, and home-made libraries), retention index determination (comparison with ADAMS library), and interpolation between C9–C31 n-alkanes. A total of 37 compounds were identified from the cyclohexane and CH₂Cl₂ extracts, including monoterpenes, sesquiterpenes, fatty acids, alkaloids, phytosterols, and pentacyclic triterpenes. Cyclomegistine, a rare alkaloid previously only isolated from S. megistophylla, was confirmed in S. follicularis, and its EI mass spectrum (m/z [M⁺.] 361(1); 333(32); 330(12); 319(20); 318(100); 290(16)) was reported for the first time. Chemotaxonomically, the alkaloid composition (e.g., acronycine, present in all Sarcomelicope species studied to date) aligns with the genus' characteristics, while the terpenoids supplement the chemical diversity of Sarcomelicope, as prior studies focused mainly on alkaloids.
