POLYGONUM GLABRUM
(WILLD)
Phylum: Magnoliophyta Class: Magnoliopsida
Order: Polygonales Family: Polygonaceae
Common name: Common marsh, buckwheat
Distribution: India, Nepal, Sri Lanka, China, Africa, Afghanistan, Japan, Malaysia
Habitat: Semiaquatic, marshy areas
Description: The leaves are lanceolate, and their arrangement is alternate spi-
ral. While the leaf base is acute, its margin is entire. The lowers are pink
and are in terminal racemes.
Compounds and activities: The bioactive compound isolated from this species
is 1,1-diethoxy propane. The extracts of leaves of this species have yielded
phenolic compounds, tannins, and alkaloids. Compounds such as four new
diesters of 2,3-dihydroxyisodrimeninol of this species have shown anti-
helmintic activities. The phenolic and alkaloid compounds of this species
have shown antibacterial activities against
Proteus vulgaris
and
Bacillus
subtilis
. The minimum inhibitory concentration (MIC) value of stem meth-
anol extract and leaf ethanol extract of this species against
B. subtilis
was
1 mg/ml. Further, the MIC values of lower ethyl acetate extract and leaf
methanol extract of this species against
Proteus vulgaris
were found to be
1 and 0.5 mg/ml, respectively (Jani et al., 2012). In another investigation,
its 1,1-diethoxy propane content has been reported to possess antimicrobial
activities to the extent of 65%.
