• Cytotoxicity / Antibacterial: Cytotoxicity and antibacterial activity
of Sida rhombifolia (Malvaceae) grown in Bangladesh: The
ethyl acetate extract showed potent cytotoxicity. Extracts showed weak
antibacterial activity against both Gram-positive and Gram-negative
• Antioxidant: Evaluation
of In Vitro Antioxidant Activity of Sida rhombifolia (L.) Ssp. retusa
(L.) : All the extracts showed effective free radica
scavenging activity, reducing activity, and superoxide scavenging activity.
The results indicate S. rhombifolia is a potential source of natural
• Antibacterial / Antifungal: In a study of nine Zairean medicinal plants, six extracts, including Sida rhombifolia, demonstrated marked antibacterial activity agaiinst K pneumonia, S aureus, Strep mutans and significant antifungal activity against A niger, C albicans and M gypseum. Most of the bactericidal and fungicidal consstituents were found in the ethyl acetate and aqueous fractions.
• Anti-Arthritic: Results of study of aerial parts of Sida rhombifolia on adjuvant-iinduced arthritis, motor performance, distance traveled and histopath findings showed it to be useful in the treatment of arthritis.
• Antinociceptive / Anti-Inflammatory: Results showed the leaves of S rhombifolia possessed antinociceptive and anti-inflammatory activities confirming its traditional uses for pain and inflammatory ailments.
• Anti-Gout / Xanthine-Oxidase Inhibitor: Earlier studies have reported that flavonoids from the crude extract possessed invitro inhibitory activity against xanthine oxidase. Study results showed the crude extract flavonoids had an inhibitory effect from 48 to 71%.
• Toxicity Studies: Acute and subchronic toxicity studies of the water extract of the root of Sida rhombifolia failed to show toxicity evidence in male and female rats.
• Antibacterial / Fruit Extracts: Study of fruit extracts showed significant in vitro antibacterial activity against most of the test bacteria. Phytochemical screening yielded alkaloids, flavonoids, and reducing sugars in the methanolic extract.
• Hypoglycemic: Study of aqueous extract of S. rhombifolia ssp. retusa leaves showed significant hypoglycemic effects in normal rats but marginal activity in STZ-induced diabetic rats.
• Bioactive Components / Antibacterial: Study yielded major phytochemical compounds such as vasicinol, Ephedrine vasicinone, and Hypaphorine. The methanol extract was effective against all phytopathogens. Results suggest a potential source of compounds against bacterial diseases in humans and plants.
• Anthelmintic: Study results showed potent antioxidant and anthelmintic activitiy. Antioxidant activity was tested using DPPH, NO scavenging and hydrogen peroxide scavenging assays. Anthelmintic activity was evaluated using the Indian earthworm Pheretima posthuma.
