The essential oil was isolated from the fruit peels of eight Rutaceae genotypes of South India by utilizing the cold pressing method and has been analyzed through GC/MS. Altogether, 28 chemical constituents were detected and grouped into seven categories based on the presence of functional groups. Among all the groups, monoterpene hydrocarbons constituted the most dominant group ranging from 86.96-100 %, followed by sesquiterpene hydrocarbons (0.32-12.27 %), other miscellaneous compounds (12.52 %), oxygenated monoterpenes (0.34-0.79 %), oxygenated sesquiterpenes (0.83 %) and aldehydes (0.46 %), respectively. Limonene was the most abundant compound found in all the samples (51.53-93.52 %), followed by γ-terpinene (19.77 % in CLMB, β-pinene (17.83 % in CLMBI; 17.02 % in CLMS; 14.58 % in CLMM; 13.11 % in CLMB), 5-Ethylidene-1-methylcycloheptene (12.52 % in CLT), sabinene (7.73% inAM) and α-pinene (5.86 % in CLMB). Principal component analysis of all the volatiles detected from the samples discriminated into two main chemotypes (limonene and γ- terpinene/β-pinene). Further, based on the rich content of limonene, γ-terpinene and β-pinene in the genotypes CS, CLMB and CLMBI, they could be the potential sources for the commercial production of essential oil in the pharmaceutical industries.
