Nigella sativa L., a common herbaceous seed spice of India and Middle East, was identified by many researchers to have a spectrum of pharmacological and nutraceutical potentials. The seeds of nigella and its oil were widely used for centuries in the treatment of various ailments throughout the world. It is an important drug in the Indian traditional system of medicine. It is established that most of the potential and fruitful activities are inbuilt in its volatile oil and protein components. Most of the therapeutic properties of this herb are due to the presence of thymoquinone and its isomers which are the major active chemical component of the essential oil. Nigella seeds are also used in food as flavouring, additive in the breads and pickles because it has very low level of toxicity. The significant content of fats, proteins and minerals in the seeds, makes nigella suitable to be investigated as a source of these nutrients. This review incorporates a deeper view into crop cultivation along with various quality parameters of N. sativa and its constituents responsible for its pharmaceutical and nutraceutical attributes.

Summary: The essential oil of fruits of Trachyspermum ammi exhibited fungitoxicity against Epidermophyton floccosum Microsporum canis and Trichophyton mentagrophytes at 900 ppm concentration. The fungitoxicity of the oil was not affected by temperature treatment up to 150°C, autoclaving and storage up to 240 days. On chemical investigation, thymol was isolated as fungitoxic factor and it exhibited toxicity against the test fungi at 1000 ppm concentration. Zusammenfassung: Das ätherische Öl der Früchte von Trachyspermum ammi zeigte fungitoxische Wirkung gegen Epidermophyton floccosum, Microsporum canis und Trichophyton mentagrophytes bei einer Konzentration von 900 ppm. Temperaturen bis 150°C, Autoklavieren und Lagerung über 240 Tage beeinflußten die Fungitoxizität des Öles nicht Bei chemischen Untersuchungen wurde Thymol als fungitoxischer Faktor isoliert, das die Testpilze bei einer Konzentration von 1000 ppm hemmte.

In this present study observed the effect of nano filler (titanate coupling agent treated nano-zirconia) on degradation behavior of PLA filled LLDPE/LDPE/MA-g-PE modified blend. Blown Films were exposed to UV light by using an accelerated weather meter (QUV). Results show that with the loading of nano-zirconia in the LLDPE/LDPE/ PLA/MA-g-PE blend, tensile strength reduced to 47-54% before total rupture. Nano composite films lose weight by 4 to 6% in 144 hrs. However, without the addition of nano filler, blends lose their weight only 0.76%. Thermal behavior of degraded nano composite blown films was studied by using Differential Scanning Calorimetry (DSC). The morphological changes were observed by the Scanning Electron Microscope (SEM). FTIR was used for change in functional group study.
