Natural habitat of Ipomoes aquatica and its invitro antimicrobial activity

Ipomoea aquatica known as water convovulus or swamp cabbage is prolific in many parts of Asia. The plant species which might be a native to China is rich in nutrient and very popular among Asian cuisine. In Malaysia, Indonesia, Sri Lanka and Vietnam the plant is called kangkong whereas in Japan it i...
