4 Discussion
Aerva lanata
is also called as
Aerva elegans
,
Illecebrum lanatum
and
Achyranthes lanata
and is
commonly known as mountain knot grass. There are
about 28 identified species of Aerva genus (Chawla et
al., 2012). This medicinal plant is locally named as
Pindidonda
in Telugu,
Chaya, Gorakh buti, Gorakh
ganja, kapurijad, Khari
and
Khali
in Hindi, C
iru-pulai
and
Ulinai
in Tamil, Kapurmadhuri in Marathi,
Bili
Himdi Soppu
in Kannada, Cherula in Malayalam,
Bhuyi
in Rajasthan,
Chaya
in Bengali,
Bhui
and
Jari
in Sindhi,
Polpala
in Sinhalese,
Kinongo
in Swahili
and
Bhadra, Ashmahabhedah, Gorakshaganja,
Pashanabheda
and
Shatakabhedi
in Sanskrit.
Aerva
lanata
has been traditionally used as a medicine for
treating various ailments. Increased antibacterial
activities of the
Aerva lanata
plant extracts were
observed against few potential bacterial pathogens as
compared to the standard drug tested highlighting their
use in treating the infections in human. Antifungal
properties of
Aerva lanata
plant extracts were
compared with the control drug and were found to
possess either similar or increased activities. A
previous research study has reported the antibacterial
activity of whole plant extract of
Aerva lanata
against
both multi-drug resistant (
Escherechia coli
and
Pseudomonas aeruginosa
which are extended spectrum
beta lactamase (ESBL) producers) and common human
pathogens (
Salmonella
typhi
,
Salmonella
paratyphi
A,
Salmonella
paratyphi
B,
Proteus
spp
,
Streptococcus
spp
,
Klebsiella
spp
,
Serretia marcescens
,
Escherechia
coli
and
Pseudomonas aeruginosa
). The study revealed
that ethanolic extract showed maximum zone of
inhibition against
Klebsiella
pneumoniae
,
Proteus
mirabilis
and
Pseudomonas aeruginosa
(ESBL). It
was also observed that ethanolic extract was ineffective
against
Salmonella
paratyphi
A. The study results also
indicated that petroleum ether and benzene plant
extract was ineffective against many bacterial species
(Murugan et al., 2014).
5 Conclusion
Very limited studies are available in literatures which
have evaluated the in-vitro and the potential in-vivo
antimicrobial properties of various plants extracts of
Aerva lanata
. In view of emerging multi-drug
resistance among various microbes isolated from
human infections, extensive research on the potential
antimicrobial activities of
Aerva lanata
plant extracts
is warranted. Future studies should include evaluating
the various plant extracts of
A lanata
for their
antimicrobial activities against proven multi-drug
resistant microorganisms responsible for serious
infections and other potential medicinal properties
both in-vitro and in-vivo.
