Antibacterial, Antifungal, and Insecticidal Potentials of Oxalis corniculata

Oxalis corniculata is a common medicinal plant widely used against numerous infectious diseases. The agrochemical potential of methanolic extract, n-hexane, chloroform, ethyl acetate, and n-butanol fractions were assessed to measure the antibacterial, antifungal, and insecticidal activities of the plant. The crude, chloroform, and n-butanol soluble fractions showed excellent activities against Escherichia coli, Shigella dysenteriae, Salmonella typhi, and Bacillus subtilis but have no activity against Staphylococcus aureus. Similarly the crude, n-hexane, and chloroform fractions were also found to have significant activity against fungal strains including Fusarium solani, Aspergillus flexneri, and Aspergillus flavus and have no activity against Aspergillus niger. Chemical pesticides have shown very good results at the beginning, but with the passage of time the need was realized to use the natural plant sources for the safe control of insects. The current study will provide minor contribution towards it. High mortality rate was recorded for the crude extract and chloroform fraction against Tribolium castaneum. The two isolated compounds 5-hydroxy-6,7,8,4′-tetramethoxyflavone (1) and 5,7,4′-trihydroxy-6,8-dimethoxyflavone (2) were evaluated for antibacterial, antifungal, and insecticidal activities. The results showed that compound 2 was more active than compound 1 against the tested bacterial strains and insects

HPLC profiling conclusively distinguished two important Unani drugs, namely, Suranjan Shirin (Colchicum autumnale) and Suranjan Talkh (Colchicum luteum)

170-173Suranjan (colchicum) is one of the prime drugs used for arthritis in Unani System of Medicine. Two varieties of the drug are available in the market under the name of Suranjan; one is Suranjan Shirin (Colchicum autumnale) and the other is Suranjan Talkh (Colchicum luteum). The two varieties are often confused with each other due to morphological resemblance. So there is a need to set a distinction between these two varieties of Suranjan. For this purpose the marker compound (Total Alkaloid Content) were estimated quantitatively and the High Performance Liquid Chromatography (HPLC) was conducted on both the drugs. 3 g of the powdered drug was extracted in petroleum ether and dissolved in 6 mL of 75% ethanol to yield test sample. Methanol at a flow rate of 1 mL/min was used as a standard. The peaks eluted were detected at 254 nm and compared with the authentic standard at 3.2 min of retention time. The colchicine concentration was found to be higher in Suranjan Talkh (0.21%) as compared to the Suranjan Shirin (0.15%). Therefore the present study offers a phytochemical concentration criterion, namely, colchicine content to distinguish between Suranjan Shirin (Colchicum autumnale) and Suranjan Talkh (Colchicum luteum)

الخصائص المشتركة بين الأدب المهجري والأندلسي

The article explicits the common characteristics of the Arabic literature of migrants and the Arabic literature in Andalus (now Spain). Arabs invaded Spain in 8th century and ruled the country for about 8 centuries. Likewise in the past century, Many Arab writers migrated to America (especially North America) and produce literature. Both the literati have great significance in Arabic literature. The article discusses the similarities of the two literatures. Both literatures have some common aspects. Both were written by Arabs but not in their home countries. Both were influenced by other literatures. In both literatures we find national affiliation towards their origin. They both explore nature and things. Nostalgia and alienation are also known. They also introduce a new type of stanza called “الموشحات”
