The genus 
Rumex 
belongs to the Polygonaceae family, and there are more than 200 
species on Earth. 16 species grow in Uzbekistan. 
Rumex
plants are widely used as 
medicinal, food, and fodder plants. 
Since ancient times, the leaves of the 
Rumex
species have been mainly eaten, while 
the roots and seeds have been used as medicines. The seeds help prevents diarrhea and 
the leaves are used to treat skin inflammation. Types of 
Rumex
have diuretic, 
hematopoietic, blood-purifying, tonic, refreshing and antipyretic properties. Extracts 
have been used to treat diarrhea and constipation, menstrual cramps, edema, and ulcers. 
Pharmacological studies have shown that extracts and isolated individual substances of 
Rumex 
species exhibit various biological activities, especially as antioxidants, 
antitumor, anti-inflammatory, and antipathogenic agents. 
The most medicinal types of 
Rumex
growing in the Flora of Uzbekistan have been 
selected and 10 species of 
Rumex

R. aquaticus

R. conglomeratus

R. confertus

R. 
crispus

R. holaezii

R. pomiricus, R. syriacus, R. tianschanicus
investigated. 
All extracts and fractions were studied for their antibacterial, antifungal, antioxidant, 
anticoagulant, cytotoxic, surface activity, insecticidal, acaricidal, repellant effects.
The chemical components were studied by column chromatography and HPLC, and 
plants with good biological activity were selected. The studied types of rumex contain 
anthraquinones 

chrysophanol, 
emodin, 
rein, 
1-
O
-methylemodin. 
Emodin, 
chryzaphanol, 1-
O
-methylemodin - compounds that have broad pharmacological 
properties, anti-inflammatory, antitumor (including cancer of the esophagus, liver and 
lung), hepatoprotective, antioxidant (strong), antimicrobial action. A method for 
obtaining the sum of anthraquinones has been developed. 
The founded that extracts and fractions of 
Rumex
species has excellent antibacterial, 
antifungal, antioxidant and anticoagulant activities.
