Phytoremedial Potential of a New Chemotype ofOcimum kilimandscharicumGuerke from Kumaun Himalaya

Journal of Essential Oil Bearing Plants (2018)

Gitu Kunwar Chitra Pande Geeta Tewari Sunita Bhatt Sonal Tripathi

Plant productivity and safety of agricultural crops growing in metal contaminated soils is emerging as a major environmental problem affecting human health. To assess the effect of metals on herbage and oil productivity and the feasibility of growing aromatic crops in metal contaminated areas, a green house pot experiment was designed in which saplings of Ocimum kilimandscharicum were planted in copper, lead and cadmium amended soils. The aerial parts of the plants were harvested after 120 days and were subjected to hydrodistillation using Clevenger. The oil composition was analyzed by GC and GC-MS. Metal content in soil and plant was determined by AAS. Significant variations were observed in the fresh weight and plant productivity while the composition of essential oil did not exhibit marked variation as compared to the control. Despite the presence of copper, lead and cadmium in the plants, they showed vigorous growth with no symptoms of morpho-phytotoxicity.

Volatile constituents ofArtemisia parvifloraBuch.-Ham. ex Roxb. from Kumaun Himalayan Region, India

Journal of Essential Oil Bearing Plants (2015)

Kiran Tewari Geeta Tewari Chitra Pande Gitu Kunwar

Artemisia parviflora Buch.-Ham. ex Roxb. (Family: Asteraceae) a perennial herb, widely distributed in hilly parts between altitude of 900–3500 and is used for the treatment of high blood pressure, diabetes and possesses anthelmintic and anti-viral properties. The essential oil of aerial parts of A. parviflora was analyzed by Gas chromatography and Gas chromatography-Mass spectrometry. A total of 45 compounds were present of which 37 compounds were identified representing 96.60 % of the oil. The oil was dominated by the presence of sesquiterpene hydrocarbons (70.24 %) such as germacrene D (41.01 %), β-caryophyllene (10.58 %) and α-humulene (7.86 %).

Effect of Heavy Metals on Terpenoid Composition ofOcimum basilicumL. andMentha spicataL.

Journal of Essential Oil Bearing Plants (2015)

Gitu Kunwar Chitra Pande Geeta Tewari C. M. Singh Girish C. Kharkwal

In a greenhouse study, saplings of Ocimum basilicum L. and Mentha spicata L. were planted in pots in four replicates on soils treated with different concentrations of lead, copper and cadmium. The essential oil composition of aerial parts was analyzed by GC and GC-MS. There was significant quantitative variation in the essential oil of Ocimum basilicum growing in all metal amended soils. In case of Mentha spicata, no significant change in essential oil composition was observed for plants grown in metal amended soils.

Variation in the chemical profile of Agrimonia aitchisonii Schönb.-Tem. aerial part from Himalayan region

Open access journal of medicinal and aromatic plants (2015)

Chitra Pande Kiran Tewari Geeta Tewari Gitu Kunwar Deepshekha Punetha

The herb Agrimonia aitchisonii is used for curing liver, gastrointestinal and respiratory related disorders. The essential oil composition of Agrimonia aitchisonii collected from two locations in Kumaun Himalaya, Uttarakhand, India was analyzed by GC and GC-MS. The oils were rich in methyl myrtenate, limonene and camphene.
