quercetin-3-O-D-glucopyranoside
kaempferol-3-O-D-glucopyranoside
LUDWIGIA HYSSOPIFOLIA
(G. DON)
Phylum: Magnoliophyta Class: Magnoliopsida
Order: Myrtales Family: Onagraceae
Common name: Seed box, primrose willow
Distribution: Africa, Asia, Sri Lanka, India, China
Habitat: Pools, shallow ditches, river edges
Description: This annual herbaceous plant grows to a maximum height
of 3 m. The stem is glabrous, branched, and green to red colored with
striations. Leaves (10 × 3 cm) are lanceolate to linear-lanceolate and white-
green. Flowers are small, axillary, solitary, and sessile with four yellow,
white, orange, or red petals that are ovate or elliptic.
Compounds and activities: An alkaloid compound, 1-[5-(1,3-benzodioxol-5-yl)-
1-oxo-2,4-pentadienyl] piperidine (piperine), possessing antitumor and
antibacterial activities was isolated from this species. Piperine exhibited anti-
tumor activity with an IC
50
value of 13.50 µg/disc. Ethyl acetate extract has
been reported to possess antitumor properties (Das
et al., 2007) and showed
73.05 and 84.14% inhibition of
Agrobacterium tumefaciens
