Compounds were identified based on the compounds’ mass spectral data and retention indices compared with those of the NIST Mass Spectral Library (December 2011), the Wiley Registry of Mass Spectral Data, 8th edition, and many authentic standards. The content (%) was calculated in triplicate using the normalization method based on the GC-MS data. The presented data are shown as the average of three replicas. (-): Unidentified in the sample. Standard deviation did not exceed 3% for any of the values. KI: Kovats index calculated on Rtx-5MS column. (Scl) S. cumini leaves, (Scf) S. cumini fruits, (Scs) S. cumini seeds, (Scb) S. cumini bark.
