Quisqualis indica plant (Stem bark) was analyzed in-vitro to evaluate biological activities including anti-microbial properties and cytotoxic potentials. The crude n-hexane, carbon tetrachloride, chloroform and aqueous soluble partitionates of the methanolic extract of the plant were subjected to the microbiological investigation against a wide range of Gram positive, Gram negative bacteria and fungi. Brine shrimp lethality bioassay was used for evaluation of cytotoxic activity of Quisqualis indica. The zones of inhibition produced by the hexane, carbon tetrachloride, chloroform and aqueous soluble partitionates of the methanolic extract of Quisqualis indica were ranged from 7-15 mm, 8-18 mm, 12-20 mm and 10-16 mm respectively at a concentration of 400μg/disc. The obtained results were compared against standard Kanamycin (30µg/disc). In case of brine shrimp lethality bioassay, the n-hexane, carbon tetrachloride, chloroform and aqueous soluble partitionates were found to show LC50 of 1.254, 0.826, 3.866 and 5.366 µg/ml respectively as compared with vincristine sulfate (with LC50 value of 0.3229 µg/ml) as a standard positive control. The obtained results confirmed the presence of anti-microbial properties and cytotoxic potentials of Quisqualis indica which supports the traditional use of this plant in various diseases caused by pathogenic microorganisms and can be a good candidate for a further anti-tumor drug study.

Bangladesh possesses a rich flora of medicinal plant. Out of the estimated 5000 species of phanerogams and pteridophytes growing in this country, more than a thousand are regarded as having medicinal properties. The aim of this study was to evaluate the in vitro antimicrobial activity and brine shrimp lethality of the whole plant extracts of Spilanthes paniculata, a plant belonging to the family Asteraceae. The crude extract, n-Hexane, chloroform and ethyl acetate soluble fraction of crude extract showed significant to moderate antimicrobial activity against three Gram positive and three Gram negative microorganisms. The zones of inhibition produced by the crude extract (methanolic extract), n-hexane, choloform and ethyl acetate soluble fractions were found to be 14.89 mm-19.40 mm, 14 mm-19.40 mm, 10.66 mm-13.50 mm and 9.50 mm-13.26 mm, consecutively at a concentration of 30 µg/disc. N-Hexane, chloroform and ethyl acetate soluble fractions of methanolic extract of Spilanthes paniculata were screened for antitumor properties using brine shrimp lethality bioassay. From the results of the brine shrimp lethality bioassay, it can be well predicted that n-hexane, chloroform and ethyl acetate soluble fractions of methanolic extract possess mild cytotoxicity on shrimp naupalii. The median lethal concentration (LC50, the concentration at which 50% mortality of brine shrimp nauplii occurred) of n-hexane, chloroform and ethyl acetate were 48.978 mg/ml, 92.61 mg/ml and 216.770 mg/ml, respectively, comparison with positive control vincristine sulphate with 0.839 mg/ml.

The purpose of the present study is to examine the antibacterial and cytotoxic properties of methanol extract of leaves of Stephania japonica. The crude methanolic extract of S. japonica, n-hexane, chloroform and ethyl acetate soluble fractions of methanolic extract were screened for their antimicrobial activity against a wide range of both Gram-positive and Gram-negative bacteria by disc diffusion method. The crude extract showed moderate and n-Hexane, chloroform soluble fraction of crude extract showed mild antibacterial activity against both Gram-positive and Gram-negative bacteria. Ethyl acetate soluble fraction of the extract showed significant antimicrobial activity against Salmonella typhi, Escherichia coli and Bacillus cereus. The zones of inhibition produced by the crude methanolic extract, n-hexane, chloroform and ethyl acetate soluble fractions were found to be 12.80-16.55 mm, 12.60 mm, 5-14.30 mm and 10-20.25 mm, respectively, at a concentration of 30 g/disc. Chloroform, n-hexane and ethyl acetate soluble fractions of methanolic extract of S. japonica were screened for antitumor properties using brine shrimp lethality bioassay. A reputed cytotoxic agent vincristine sulphate was used as a positive control. From the results of the brine shrimp lethality bioassay, it can be well predicted that chloroform and ethyl acetate soluble fractions of methanolic extract of S. japonica possess cytotoxic principles (with LC50 66.488 mg/ml and LC50 45.662 mg/ml, respectively) comparison with positive control vincristine sulphate (with LC50 0.839 mg/ml). But n-hexane soluble fractions of methanolic extract of S. japonica exhibited no lethality effect on shrimp nauplii.

The methanol extract of leaf of Picrasma javanica as well as its n-hexane, carbon tetrachloride,chloroform and aqueous soluble partitionates were subjected to screening for antioxidant and thrombolytic activities and brine shrimp lethality. The antioxidant potential was evaluated by DPPH, Folin-Ciocalteau reagent and phosphomolybdenum total antioxidant assays using butylatedhydroxytolune (BHT) and ascorbic acid as standards. All fractions showed moderate to strong antioxidant activity, of which the chloroform and aqueous soluble fractions demonstrated the highest activity with the IC50 value of 14.59 ± 0.73 ?g/ml and 18.6 ± 0.15 ?g/ml, respectively. The  total phenolic content of the chloroform and aqueous soluble fractions was 10.4 ± 0.64 and 5.15 ± 0.22 mg of GAE/g of extractive, respectively. Thus, a positive correlation was found between the total phenolic content and total antioxidant activity of P. javanica. The general toxicity was determined by brine shrimp lethality bioassay where the crude extract (LC50 1.04 ± 0.31 ?g/ml) and its n-hexane (LC50 1.28 ± 0.45?g/ml) soluble partitionate demonstrated the  presence of considerable bioactive principles. Mild to moderate thrombolytic activity was discerned by the methanol extract of leaf of P. javanica and its different fractions. During assay for thrombolytic activity, the carbon tetrachloride soluble materials revealed 34.165±1.57 % of clot lysis while standard streptokinase and water, used as positive and negative controls, demonstrated 66.77% and 3.791% lysis of clot, respectively.

Cryptocoryne ciliata belonging to the Araceae family has been investigated for isolation of its secondary metabolites and evaluation of biological activities of the crude extractives with special emphasis to the antioxidant activity and brine shrimp lethality bioassay. The whole plant was extracted with methanol and concentrated extract was partitioned using petroleum ether, carbon tetrachloride and ethyl acetate. Aqueous soluble fraction of the methanolic extract showed the highest antioxidant activity. The carbon tetrachloride soluble fraction of the methanolic extract and the ethyl acetate soluble fraction of the methanolic extract showed moderate antioxidant activity as compared to free antioxidant activity of tert-butyl-1-hydroxytolunene. In the brine shrimp lethality bioassay, among all extracts of whole plant of C. ciliata, the carbon tetrachloride soluble fraction of the methanolic extract showed strong cytotoxic activity. Aqueous soluble fraction of the methanolic extract, methanolic crude and ethyl acetate soluble fraction of the methanolic extract showed mild cytotoxity as compared to that of vincristine sulphate. The study confirms the mild to moderate antioxidant and moderate potent cytotoxic activities of C. ciliata plant extract as compared to reference standards and therefore demands the isolation of active principles and thorough bioassay.DOI: http://dx.doi.org/10.3329/icpj.v2i2.13196 International Current Pharmaceutical Journal 2013, 2(2): 38-41
