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.
