ALTERNANTHERA SESSILIS
(L) R. BR. EX DC.
Phylum: Magnoliophyta Class: Magnoliopsida
Order: Caryophyllales Family: Amaranthaceae
Common name: Sessile joy weed, dwarf copper leaf
Distribution: World distribution
Habitat: Ditches, damp places, wet headlands
Description: This perennial herb, which grows to a height of 50 cm, has pros-
trate stems. Leaves (15 × 3 cm) are elliptic or obovate. The lowers are in
sessile spikes.
Compounds and activities: The chloroform extracts of air-dried leaves of this
species possess a mixture of diastereomers of a new lonone derivative,
which show antimicrobial activities against
Pseudomonas aeruginosa
and
Trichophyton mentagrophytes
and large amounts of carotenes. The crude
extracts of this species have also been reported to possess cytotoxic (against
three cancer cell lines), antioxidant, hematinic (hemoglobin and serum ferri-
tin enhancement), and antilipidemic (anticholesterolemic) activities (Jalalpure
et al., 2008; Arallado and Osi, 2010). In traditional medicines, this plant is
used for treating gastrointestinal problems. The methanol extract of the leaves
of this species possesses nootropic potential (memory-enhancing effect).
