Species of flowering plant in the family Alismataceae

Sagittaria sagittifolia (also called arrowhead because of the shape of its leaves) is an Old World flowering plant in the family Alismataceae.

Sagittaria sagittifolia is a herbaceous perennial plant, growing in water from deep. The leaves above water are arrowhead shaped, the leaf blade long and broad, on a long petiole holding the leaf up to above water level. The plant also has narrow linear submerged leaves, up to long and 2 cm broad. Panicled flowers are 2–2.5 cm broad, with three small sepals and three white petals, and numerous purple stamens.

It is native to wetlands in most of Europe (it is extinct in Spain) and Asia in Finland and Bulgaria, in Russia, Ukraine, Siberia, Turkey and the Caucasus.

The round tuber is edible. It is starchy with a bland flavour and a texture similar to a potato but somewhat crunchier, even when cooked. In Japan, it is known as クワイ (慈姑) and its tuber is eaten particularly during the New Year. In China, it is known as 慈姑 and often used in winter hot pots. Remnants of Sagittaria sagittifolia have been found in the Paleolithic/Mesolithic site of Całowanie in Poland. S. sagittifolia is used in Chinese medicine, and in 2006 seven new ent rosane diterpenoids and a new labdane diterpene were purified from the plant. Four of these compounds (Sagittine A–D) exhibited antibacterial activity against Streptococcus mutans and Actinomyces naeslundii while another (Sagittine E) was only active against A. naeslundii (MIC = 62.5 μg ml–1). Recently, the same group identified five new diterpenoids from Sagittaria pygmaea. None displayed activity against A. actinomycetemcomitans, while four of the others were active against A. viscosus and three against S. mutans, of which 18 ß D 3',6' diacetoxyglucopyranosyl ent kaur 16 ene was the most active.
