Mineral composition and antimicrobial activity of <i style="mso-bidi-font-style:normal">Swertia cordata</i> (G. Don) Clarke aerial parts and roots
273-277The study aim was to evaluate the concentration of
mineral elements and antimicrobial activity of <i style="mso-bidi-font-style:
normal">Swertia cordata
(G. Don) Clarke aerial parts and roots. Macro minerals, viz. sodium,
potassium, calcium, lithium were estimated by
Flame Photometer while micro minerals, viz. iron, copper, manganese, zinc and
cobalt were determined by Atomic Absorption Spectrophotometer. Among all the
elements, highest concentration of potassium was recorded in both aerial parts
(385.6 mg/100 g) and roots (421.3 mg/100 g) of <i style="mso-bidi-font-style:
normal">S. cordata. Methanol extract of both <i style="mso-bidi-font-style:
normal">S. cordata aerial parts and roots obtained by Soxhlet extraction
were screened for their antimicrobial activity against 6 bacteria and 2 fungi
using disc diffusion method. The results showed that both the extracts
exhibited moderate antibacterial activity while roots showed good antifungal
activity against Candida albicans
(ZOI =20 mm)
Chemical composition and antimicrobial activity of the essential oils of <i style="">Senecio rufinervis</i> DC. (Asteraceae)
44-47The chemical composition of the essential oil obtained from the
leaves and roots of Senecio rufinervis DC.
was analyzed by GC, GC/MS and NMR. Germacrene D was the major constituent in
both the oils studied (40.19 and 24.95%, respectively). The antimicrobial
activity of the oil was determined by disc diffusion method. Results showed
that both the oils exhibited significant antibacterial activity
