Ficus Glomerata

The present study was carried out to investigate the thrombolytic and antimitotic potentiality of various extracts of fruits of Ficus glomerata, a traditional medicinal plant, using an in vitro assay method. Three crude extracts such as petroleum ether (FGPE), chloroform (FGCE), and methanol (FGME) were used for the study, with a standard (streptokinase) and negative control (sterile distilled water) to validate the method. The thrombolytic nature of the plant was found significant with methanol extract and chloroform and petroleum ether extracts have recorded mild activity, when compared with the negative control (sterile distilled water). The extracts have shown mild clot lysis, that is, 2.16%, 23.06%, 27.60%, and 47.74% of sterile distilled water, FGPE, FGCE, and FGME, respectively, while the standard (streptokinase) has shown 74.22% clot lysis. FGME inhibited the root growth in number as well as length effectively, followed by FGPE, while FGCE exhibited moderate antimitotic activity and it was supported by mitotic index. Therefore, the obtained results suggest that among all the extracts of plant the methanolic extract has shown highest thrombolytic and antimitotic activity.

Crude Methanol Extract

Brassica rapa subsp. chinensis (L.) Hanelt is a popular herb in Bangladesh. In the present studies, the plant has been assessed to evaluate its in vitro thrombolytic and membrane stabilizing properties. Initially, the plant was collected, processed and extracted with methanol and the concentrated crude methanol extract was fractionated into petroleum ether, carbon tetrachloride, chloroform and aqueous soluble materials. All extractives, including the parent extract were subjected to thrombolytic and membrane stabilizing bioassays. In case of thrombolytic study, the carbon tetrachloride soluble fraction exhibited highest clot lysis. Here, streptokinase and distilled water were used as positive and negative control, respectively. However, in the assay for membrane stabilizing activity, the crude methanol extract along with other extractives were capable to inhibit hemolysis of erythrocyte membrane in hypotonic solution- and heat- induced conditions, which indicated anti-inflammatory property of the samples. Acetyl salicylic acid was used as standard drug in this assay. This represents the first report of thrombolytic and membrane stabilizing activities of B. rapa subsp. chinensis.

Background: Anchusa azurea Mill. (AA) is a medicinal plant largely used traditionally in folk medicine in Algeria, it is locally named: hamham. It is effective in the treatment of various diseases. Objectives: The aim of the present study is to determine the antioxidant, anti-inflammatory and anti-hemolytic effects of phenolic fractions from Anchusa azurea Mill. Methods: In this study, various extracts from Anchusa azurea Mill. (AA) using solvents with increasing polarity were prepared. The quantification of polyphenols and flavonoids was determined. The anti-radical activity of the different extracts was evaluated using DPPH and by measuring the inhibition of the oxidative degradation of β-carotene. The In vitro antihemolytic effect of the plant extracts is determined (CrE, ChE, AcE and AqE). For each extract, four concentrations were tested: 10.59, 21.18, 42.37, 84.74 µg/ml. Vitamin C is used as a standard. Free-radical attack was measured by measuring the HT50 (Half-Hemolysis Time). The anti-inflammatory effect using PMA on mice of the methanolic extract (CrE) was evaluated. Results: The quantification of polyphenols and flavonoids showed that ethyl acetate extract (AcE) contains a higher amount of polyphenols. However, chloroform extract (ChE) presents a higher amount of flavonoids. AcE showed an important scavenging activity using the DPPH radical (IC50= 68.35 µg/ml). The results showed that AcE also exhibited very great inhibition on the oxidation of β-carotene/linoleic acid (84.33%). All extracts increased the HT50 values (Half-Hemolysis Time) in a dose-dependent manner. The three highest concentrations (21.18, 42.37 and 84.74 µg / ml) of ChE caused a very significant delay (p ≤ 0.001) of hemolysis compared to the negative control and the positive control "VIT C". The anti-inflammatory effect using PMA on mice showed that the methanolic extract (CrE) of AA reduced the weight of the ear edema. Conclusions: This plant has a strong pharmacological power, which supports its traditional medicinal use.

Abstract Background Campsis radicans L. is a flowering plant in Bangladesh, traditionally used for the treatment of several human diseases. In this study, in vitro antioxidant, thrombolytic, membrane stabilizing and in vivo analgesic, hypoglycemic, anti-diarrheal and CNS antidepressant activities of organic soluble fractions of crude methanol extract of C. radicans leaf were investigated using appropriate experimental models. Methods The leaves of C. radicans were collected, authenticated, dried and extracted with methanol at room temperature for 30 days. The concentrated methanol extract was partitioned to petroleum-ether (PESF), dichloromethane (DMSF) and ethyl acetate (EASF) soluble fractions. The antioxidant activity of these fractions was determined by DPPH free radical scavenging method. Total phenolic content was determined by the Folin-Ciocalteau’s spectrophotometric method. The thrombolytic activity was assessed by measuring clot lysis ability whereas the membrane stabilizing activity was evaluated by heat- and hypotonic solution-induced hemolysis assay. Tail immersion procedure and acetic acid- induced writhing model were used to measure the analgesic activity of C. radicans. The hypoglycemic, anti-diarrheal and CNS antidepressant activities were determined by oral glucose tolerance test, castor oil-induced diarrheal model and thiopental-sodium induced sleeping time test in mice, respectively. Results All the organic soluble fractions of C. radicans contained phenolic compounds varying from 6.38 to 60.13 mg of GAE/gm of extractive, while in DPPH assay, EASF showed the highest free radical scavenging activity with IC50 is 4.69 μg/ml. The PESF exhibited highest thrombolytic activity (57.14% clot lysis) and the DMSF showed maximum 53.95% inhibition of heat-induced hemolysis of human RBCs. In both tail immersion and acetic acid induced writhing models, the PESF, DMSF, EASF at the doses of 200 and 400 mg/kg body weight, induced a significant (P < 0.001) decrease in the painful sensation in mice. Substantial (P < 0.05) anti-hyperglycemic activity of test samples was found in mice loaded with glucose at the same doses mentioned earlier. Castor oil induced diarrheal test of the plant extractives has shown significant effect in comparison to control group. In CNS antidepressant activity assay, the test samples were able to reduce the duration of sleep in mice caused by thiopental administration. Conclusion All these findings revealed that C. radicans possess significant antioxidant, thrombolytic, membrane stabilizing, analgesic, hypoglycemic, anti-diarrheal and CNS antidepressant activities.

The study was designed to investigate the antioxidant activities of the methanolic extract of leaves of Begonia roxburghii by five different in vitro methods namely Folin-Ciocalteu, total flavonoid content, phosphomolybdenum, total reducing power determination, and DPPH scavenging activity. Phenol content (Gallic acid equivalent) was found as 180.40±0.03 mg/g of the dry sample by the Folin-Ciocalteu method. Flavonoid assay method revealed the content of flavonoids (Quercetin equivalent) as 60.43±0.27 mg/g of the dry sample. Total antioxidant capacity of the extract was observed 243.43±0.11 mg/g ( ascorbic acid equivalent) by phosphomolybdenum method. Free radical scavenging activity (measured by the DPPH test) of the methanolic extract was found 158.36±0.22 μg/mL whereas ascorbic acid, the standard, showed 19.53±0.04 μg/mL. The methanolic extract of Begonia roxburghii leaves exhibited positive and linear dose dependent reducing power activity and its activity was comparable to the standard ascorbic acid for a given dose. Phytochemical screening of the extract showed positive results for alkaloids, carbohydrates, flavonoids, glycosides, saponins, steroids, and tannins, which demonstrate definite pharmacological actions on human body. The extract showed negative results for the steroids. Jahangirnagar University J. Biol. Sci. 9(1 & 2): 79-89, 2020 (June & December)
