Determination of seasonal variation of volatile organic constituents of the leaves of traditional herb ocimum sanctum linn - Vol.83(4), July-Aug - Mumbai Indian Journal of Pharmaceutical Science 2021 - 750-757p.
In the traditional system of medicine Ocimum sanctum Linn. is used to cure diseases like dysentery,
bronchitis, malaria, bronchial asthma, diarrhea, arthritis, skin diseases, painful eye diseases, chronic
fever. The essential oil obtained by using hydrodistillation of the leaves of Ocimum sanctum Linn. (purple
variety) is collected throughout 1 y and analyzed employing gas chromatography equipped with flame
ionization detector and gas chromatography connected with mass spectrometry. The yield of essential oil
varied in the range from 0.14 to 0.21 % (w/w). 23 to 39 constituents were identified which represented
95.39±0.38 % of the total oil. The most abundant compound was identified as methyl eugenol with an
average of 69.88±0.09 % with varying quantities from 55.48±0.36 to 76.78±0.54 %. The other constituents
were beta-caryophyllene 10.40±0.06 %, alpha-ylangene 4.18±0.04 %, gamma-muurolene 3.64±0.04 % and
borneol 2.02±0.01 %. The oil was found to be rich in phenylpropanoid (71.98±0.27 %) type constituents
(average of 12 mo). A high amount of methyl eugenol (76.78±0.54 %) was observed during November while
low (55.48±0.36 %) in April. It was noticed that when the plant was matured in April the accumulation of
sesquiterpenes increased and phenylpropanoids decreased.
