SAGITTARIA SAGITTIFOLIA
LINNAEUS
Phylum: Magnoliophyta
Class: Liliopsida
Order: Alismatales
Family: Alismataceae
Common name: Arrowhead
Distribution: Europe, Asia
Habitat: Wetlands
Description: It is a herbaceous perennial plant growing in shallow waters (50 cm
deep). Leaves above water are arrow shaped, and their blades measure 25
cm long and 20 cm wide. Narrow, linear, submerged leaves are also present.
Flowers that are 2 cm broad have white petals and three small sepals.
Compounds and activities: The ent-rosane diterpenoids, viz., sagittines A-D
and 13- epi- manoyl oxide-19- O- α-L-2-5′-diacetoxyrabine furonoside, have
been isolated from this species. Among them, sagittines A-D exhibited
antibacterial activity against oral pathogens such as
Streptococcus mutans
and
Actinomyces naeslundii
. The MIC values of these species ranged from
62.5 and 125 μg/ml (Liu et al.,
2006).
