Christia vespertilionis (L. f.) Bakh. f. is well-known for treating various contagious diseases. This plant has been recognised among researchers and locals to have anti-inflammatory properties and has thus become popular for treating cancer. Two types of C. vespertilionis are acknowledged which are green and red. The green C. vespertilionis has been widely studied by many researchers, however just a few have studied the red type. This study was carried out to optimise the extraction method of red C. vespertilionis leaves by different extraction techniques (maceration and Soxhlet extraction) and solvents (methanol and ethanol) to yield bioactive phytochemicals using gas chromatography-mass spectrometry (GC-MS). The components were identified through GC-MS via comparisons as guided by the National Institute of Standards and Technology Mass Spectral Library 2011 (NIST 11, version 2.0g). According to the four (4) samples of red C. vespertilionis leaves using maceration of methanol (RMM), maceration of ethanol (RME), Soxhlet extraction of methanol (RSM), and Soxhlet extraction of ethanol (RSE), seventy-one (71) bioactive phytochemicals were identified. Eleven (11) major bioactive phytochemicals (abundance of > 4) were identified namely, acetic acid, butyl ester; 1-butanol, 3-methyl-, acetate; heptanoic acid, propyl ester; hexanoic acid, 3-oxo-, ethyl ester; phenol, 3,5-bis(1,1-dimethylethyl)-; 1-octadecene; 4-O-methylmannose; .alpha.-d-mannofuranoside, methyl; 2-undecene, 9-methyl-, (E)-; n-hexadecanoic acid; and 1-octadecanol. Only seven (7) out of eleven (11) compounds were reported to have biological activities. Among those samples, RSM was the most effective using correlation coefficient between abundance () and retention time (minute(s)) with a significant difference at P < 0.05. © 2022, Malaysian Society of Analytical Sciences.
