Pharmacognostic Study of Some Phytochemically Unexploited Floristic Trees of Hathwa, Gopalganj (Bihar)

Abstract

Pharmacognosy of Indian plants has been a perk for studies and medicinal researches. Hathwa has been blessed with
Flora with extraordinary nutritional and medicinal benefits. Plants of Moringa oleifera (Lam.), Holarrhena antidysenterica
(Roth)Wall, Erythrina indica (Lam.) were found to be present at outskirts of Hathwa region of Gopalganj Bihar, They have been
traditionally used in several disorders faced by human body but the stringent record and detailing is missing and this research
was accomplished to relate their antimicrobial activities with their phytochemical entities. The plant extracts of bark was chosen
because of its abundance presence and easy availability. The extracts were found positive for phenol, quinine, steroids, protein
and amino acids The time-kill kinetics profile of extract of bark of H. antidysentrica (Roth) against the test organisms
K. pneumoniae, P. aeruginosa and V. cholerae at the test concentrations of Moringa oleifera showed reduction in number of viable
cells over the first 4, 8, and 12 hours P. aeruginosa, and V. cholerae, respectively, followed by a gradual rise up to the 10th?h and
14thh for K. pneumoniae when compared to the control (organisms without antimicrobial agent).The time-kill kinetics profile of
extract against the test organisms; at test concentrations studied showed reduction in number of viable cells over the first 2, 6,
and 24 hours K. pneumoniae, P. aeruginosa, and V. cholerae respectively, followed by a gradual rise up to the 24thh for P. aeruginosa
and V. choleraeand 12thh for K. pneumonia when compared to the control. Therefore from our research it was concluded that
Moringa oleifera (Lam.), Holarrhena antidysenterica (Roth)Wall, Erythrina indica (Lam.) plants present at the outskirts of Hathwa
region possess antimicrobial properties with important nutritional values. The aim of our research was to target some crucially
important plants of Hathwa Gopalganj Bihar to study their antimicrobial potential, and this research targeted to explore the
Phytoconstituents of those used plants which made them potent for antimicrobial activity.
