This study aimed to evaluate the in vitro thrombolytic potential of Mimosa pudica (Makahiya) using the crude extract of the plant. This study utilized randomized controlled trial to determine the thrombolytic potential of Mimosa pudica (Makahiya) plant extract on the Citrated Platelet Poor Plasma. Makahiya plant was subjected to the phytochemical screening tests to determine the presence of glycosides. The study utilized twenty-one (21) healthy human subjects with normal Prothrombin time results to ensure that no recent or history of oral or intravenous anticoagulation therapy was taken. The volunteers’ blood sample were collected and subjected to centrifugation to yield citrated platelet-poor plasma. This study utilized the Euglobulin Clot Lysis Time to determine the thrombolytic potential of Mimosa pudica (Makahiya). 0.5 mL of citrated platelet poor plasma was placed into 3 test tubes labeled as positive control, experimental control, and negative control. The plasma was diluted and acidified to precipitate the euglobulin fraction. The tubes were added with 25 μL of thrombin to induce clot formation and the stopwatch was started immediately. Once clot was formed, test tube 1 was added with the 25 μL of Makahiya plant extract, and served as the experimental control. Test tube 2 was added with 25 μL of Streptokinase which served as the positive control. Test tube 3 only contained the citrated platelet poor plasma and served as the negative control.
The mean percent euglobulin clot lysis time in minutes of blood samples treated with Makahiya plant extract, Streptokinase, and untreated blood samples are 3.27 + .15, 2.33 + 3.7, and 360 respectively. Wilcoxon signed ranks test revealed that there was a significant difference between the median euglobulin clot lysis time in minutes of the blood samples treated with Makahiya extract and Streptokinase at .05 level of significance, z = -2.371 and p < .05. On the average, blood samples treated with makahiya extract (Median = 3.18) had longer euglobulin clot lysis time compared to the blood samples treated with streptokinase (Median = 2.54).
Based on the findings, Mimosa pudica (Makahiya) plant crude extract had an in vitro thrombolytic potential on citrated platelet poor plasma.

In case of cytotoxic activity observation, Brine shrimp lethality bioassay testing method was used, 5% DMSO and brine shrimps were used as test materials, where DMSO as solvent for proper solution. The percent of thrombolysis by the extract showed 43.067 ± 3.0601%, whereas percent of thrombolysis by streptokinase was found 68.582 ±1.7764%. From the cytotxicity study of the crude extract LC50 was found 1.981µg/ml with 95% confidence limit was 1.7299-2.2706 µg/ml. The current study refers the plant leaves as impressive thrombolytic and cytotoxic agent for further laboratory study.

The methanolic extract of the leaves of Smilax lanceifolia Roxb. (Family-Smilacaceae) was subjected to pharmacological investigation to ascertain analgesic and antibacterial activity.. The phytochemical screening demonstrated the presence of different types compound like anthraquinone glycoside, alkaloids, terpenoids, tannins, carbohydrate,flavone aglycone, saponin, phenolic compound, reducing sugar, and phlobotannin. The methanolic extract of the plant was tested for analgesic activity using chemical writhing method (0.6% acetic acid) and antibacterial activity against Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi bacteria using cup diffusion method. The extract significantly(p<0.05) inhibited in a dose dependent fashion analgesia(nociception) induced by acetic acid as indicated by the reduction in number of writhing movement in mice. Antibacterial activity was observed against S.aureus, S.typhi, E.faecalis, and E.col...
