Abstract

Litsea umbellata (Lour.) Merr) is quite common in our country and grows in many places: Lao Cai, Vinh Phu, Gia Lai, Kontum,.... The study aimed to describe the morphological characteristics, Anatomy and antioxidant activity of bitter leaf extracts. The results show that: Boi Lii has a well-developed root that penetrates deep into the ground, the root size is relatively equal. In the secondary structure of bitter gourd roots, the wood and libe are arranged in an open superimposed bundle. Stems have thick tissue at the primary stem. Hard tissue forms a ring around the body. Vascular bundles are many, they are linked together by a wood beam system. Intestinal soft tissue located in the midsection of the body is composed of polygonal or slightly rounded cells of different sizes. Leaves alternate, oval, oblong-oval, narrow or rounded at base, pointed at tip, often clustered at branch tips, hedging tissue has a strongly developed layer, underside of leaf has stomata. transpiration and gas exchange with the environment. The ethanol extract of bitter gourd leaves has high oxygen activity with an average IC50 value of 3.22 µg/ml. From the research results, it is shown that bitter gourd is a potential medicinal plant containing many antioxidant compounds.
