Sagittaria sagittifolia (also called arrowhead because of the shape of its leaves) is an Old World flowering plant in the family Alismataceae.
Description
Sagittaria sagittifolia is a
Distribution and habitat
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.[1] It is also cultivated as a food crop in some other countries. In Britain it is the only native species of Sagittaria.[4][2]
Ecology
S. sagittifolia can be weedy or invasive according to the
Uses
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 kuwai クワイ (慈姑) and its tuber is eaten particularly during the New Year.[dubious ] In China, it is known as 慈姑 cígū and often used in winter hot pots.[3] In Vietnam, the plant's young petiole leaves and rhizomes are used for soups.[6][dubious ]
Remnants of Sagittaria sagittifolia have been found in the Paleolithic/Mesolithic site of Całowanie in Poland.[7]
S. sagittifolia is used in Chinese medicine,[citation needed] 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.[8]
