Melon Seeds

Frequently, stored melon seeds fail to preserve to their time of use. Storage fungi invade these seeds and cause their deterioration. A study was, therefore, carried out to determine the effect of guava (Psidiumguajava L.) leaf and ginger (Zingiberofficinale) rhizome extracts on the sporulation and spore germination of the invading seed fungi.Dried leaves and rhizomes were ground in sterile mortar, filtered through a wire sieve and then extracted usingthree different solvents. Results revealed that both extracts hindered sporulation and spore germination in the four fungi tested namely: Aspergillusflavus, A. niger, Rhizopusstolonifer and Fusarium species. The effect of the extracts on the test organisms increased with concentration of the extracts. Phytochemical screening confirmed the presence of alkaloids, saponins, lipids,tannins, flavonoids, and steroids. A reduction in nutrient contents was also observed in infested melon seeds. These results are significant and would serve as a template for planning the control of storage fungi in melon seeds in particular and other crop produce in general.

Sheath Rot

Sarocladium oryzae (Sawada) W. Gams & D. Hawksworth, the causal agent of sheath rot of rice was isolated from sheath rot infected rice sheaths and grains. Among ten tested fungicides Tall 25 EC completely inhibited radial growth of the fungus even at the lowest concentration 100 ppm. Similarly ethanol leaf extract of ten plants, namely Allium sativum, Artocarpus heterophyllus, Asparagus racemosus, Azadirachta indica, Citrus medica, Datura metel, Mangifera indica, Nerium indicum, Senna alata and Tagetes erecta at 5, 10 and 20% concentrations were screened for their fungicidal activity against the test fungus. All the plant extracts completely inhibited the radial growth of the test fungus at 20% concentration except Asparagus racemosus and C. medica. Ethanol extract of Tagetes erecta and Mangifera indica also completely inhibited the radial growth of the test fungus at 10% concentration.Bangladesh J. Sci. Res. 29(1): 47-54, June-2016

Eupatorium Japonicum

The oral LD50 of Crotalaria assamica, which contains mainly monocrotaline, was found to be 154 mg/kg in mice. Neither liver necrosis nor morbidity was demonstrated with Eupatorium extract at a dose level of 144 mg/kg, which was equivalent to the LD20 of Crotalaria. Pretreatment with phenobarbitone enhanced the toxicity of both plant extracts in mice. In in vitro studies, "metabolic pyrrole" was formed by incubating Eupatorium japonicum extracts with liver microsomes. The rate of "pyrrole" formation was similar to that of Crotalaria extract and pure monocrotaline alkaloid, but was much slower than retrorsine. The rate of N-oxide formation was, in descending order, retrorsine, Eupatorium japonicum and Crotalaria/monocrotaline. It is concluded that the alkaloid in Eupatorium species is metabolized to "pyrrole" and an N-oxide metabolite in the liver, but hepatotoxicity is much lower when compared with that caused by Crotalaria.

Antimicrobial Studies

Preliminary characterization of phytocompounds from stem bark of Anogeissusleiocarpus and its antimicrobial effects was carried out in this study. Concentrated and dried extracts obtained, after extraction of the plant material, were subjected to phytochemical screening and FT-IR analysis. Part of extracts obtained were used for antimicrobial studies on eleven pathogenic clinical isolates namely Methicillin resistant Staphylococcusaureus, Vancomycin resistant enterococci, Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Klebsiella pneumonia, Proteus mirabilis, Salmonella typhi, Candida krusei, Candida albicans and Candida stellatoidea using standard protocols. Phytochemical screening of the plant extracts revealed the presence of, alkaloids, steroids, saponins, tannins, flavonoids and reducing sugars. FT-IR's spectroscopic analysis showed characteristic peaks of alcohols, ethers, esters, carboxylic acids, aldehydes, ketones and amines groups matching with some of the metabolites’ functionalities already reported in literature. The plant extracts were active against all the test organisms (MIC ranged from 5.0 mg / ml to 1.25 mg / ml; MBC/MFC ranged from 10 mg / ml to 2.5 mg / ml) except Methicillin resistant Staphylococcusaureus, Staphylococcus aureus, Klebsiella pneumonia and Candida krusei. It can be concluded that the stem-bark of Anogeissusleiocarpus contains phytochemicals that have potentials to be developed into antimicrobial drugs useful for the treatment of diseases caused by those microorganisms the plant indicated activity against it.
