Composition and antioxidant activity of Senecio nudicaulis Wall. ex DC. (Asteraceae): a medicinal plant growing wild in Himachal Pradesh, India. Natural product research, 2015, Volume: 29, Issue:9 The composition of essential oil isolated from Senecio nudicaulis Wall. ex DC. growing wild in Himachal Pradesh, India, was analysed, for the first time, by capillary gas chromatography (GC) and GC-mass spectrometry. A total of 30 components representing 95.3% of the total oil were identified. The essential oil was characterised by a high content of oxygenated sesquiterpenes (54.97%) with caryophyllene oxide (24.99%) as the major component. Other significant constituents were humulene epoxide-II (21.25%), α-humulene (18.75%), β-caryophyllene (9.67%), epi-α-cadinol (2.90%), epi-α-muurolol (2.03%), β-cedrene (1.76%), longiborneol (1.76%), 1-tridecene (1.16%) and citronellol (1.13%). The oil was screened for antioxidant activity using DPPH, ABTS and nitric oxide-scavenging assay. The oil was found to exhibit significant antioxidant activity by scavenging DPPH, ABTS and nitric oxide radicals with IC50 values of 10.61 ± 0.14 μg mL(- 1), 11.85 ± 0.28 μg mL(- 1) and 11.29 ± 0.42 μg mL(- 1), respectively.

Constituents of essential oils from the leaf and flower of Plumeria alba grown in Nigeria. Natural product communications, 2014, Volume: 9, Issue:11 This paper reports on the compounds identified in the leaf and flower essential oils obtained by hydrodistillation of Plumeria alba L. (Apocynaceae) grown in Nigeria. The chemical analysis of the essential oils was achieved by means of gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS). Linalool (13.2%), n-nonanal (9.6%), phenyl acetaldehyde (8.5%), neryl acetone (5.3%) and n-decanal (5.1%) were the main constituents of the leaf oil. On the other hand, the flower oil comprised mainly of limonene (9.1%), linalool (7.9%), α-cedrene (8.0%), caryophyllene oxide (7.9%) and (E, E)-α-farnesene (6.6%). This is the first report on the essential oil constituents of P. alba.
