In traditional medicine, the plant Ocimum gratissimum L. (Lamiaceae) is employed in neurological specialty and rheumatic affections, in seminal weakness, and aphthae of children. In homeopathy, the recent mature leaves are employed in constipation, cough, fever, nasal catarrh, and additionally in gonorrhea with troublesome urination. The essential oil is obtained by a Clevenger sort equipment from leaves of Ocimum gratissimum L. (Lamiaceae) acquired during one year. The chemical composition of the essential oil is examined by exploitation of gas chromatography fitted with a flame ionization detector (GC-FID) and gas chromatography connected with mass spectrometry (GC–MS). The antioxidant activity of oils and eugenol was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH·) colored persistent radical assay. The yield variation of oil was found to be within the purview of 0.17 to 1.07% (w/w). Thirty-four to 42 known constituents were delineated as 97.27 ± 0.27% of the entire oil. Eugenol was an associated significant compound in inconsistent amounts ranging from 65.65 ± 0.57 to 85.71 ± 0.55%, in accord with modest variations among different constituents. It was ascertained that no rain throughout January and February led to the monoterpene organic compound (Z)-β-ocimene being a rarity in high amounts and eugenol having low amounts. Essential oils of O. gratissimum collected throughout the study year showed antioxidant activity with IC50 values within the purview of 2.04 ± 0.04 to 3.02 ± 0.03 μg/mL. The essential oil gathered in June showed higher antioxidant activity with an IC50 value of 2.04 ± 0.04 μg/mL, and that gathered in February showed the lowest IC50 value of 3.02 ± 0.03 μg/mL. The months March to November were favorable for the synthesis of a high quantity of medicinally vital eugenol by O. gratissimum within the range of 81.71 ± 0.34 to 85.71 ± 0.55% with antioxidant activity less than 3.0 μg/mL.

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.

The present study explored essential oil constituents of the medicinal plants used in traditional medicine and growing wild in the Western Ghats region of India, which is one of the 34 global biodiversity hotspots. The hydro distilled essential oils of Blumea lanceolaria (Roxb.) Druce. (Asteraceae), Heliotropium indicum L. (Boraginaceae) and Triumfetta rhomboidea Jacq. (Tiliaceae) were analyzed using gas chromatography equipped with a flame ionization detector (GC-FID) and gas chromatography coupled with mass spectroscopy (GC/MS). Thirty-six, twenty-seven, and fifty constituents were identified from the essential oils of B. lanceolaria, H. indicum, and T. rhomboidea, respectively comprising 97.3% (B. lanceolaria), 98.2% (H. indicum) and 97.6% (T. rhomboidea) of the total oil constituents. The major compounds of B. lanceolaria, H. indicum, and T. rhomboidea were identified as β-pinene (82.3%), methyl salicylate (54.3%), and β-caryophyllene (28.9%), respectively. The essential of B. lanceolaria was found to be rich in monoterpene hydrocarbons (90.4%), while H. indicum and T. rhomboidea oils were rich in phenyl derivative (72.8%) and sesquiterpene hydrocarbons (69.5%) type constituents, respectively. The common compounds viz., terpin-4-ol and eugenol were identified in the essential oils of B. lanceolaria, H. indicum, and T. rhomboidea.
