Studies
• 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
test organisms.
• 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
antioxidants.
