a pressurized fluid extraction (pfe) method for the extraction of pistachio oil was developed using a modified supercritical fluid extractor. the supercritical fluid extraction apparatus was modified to be able to pump liquid solvent and co2 into the extraction vessel alternatively. the experimental results showed that the extraction yield was independent of the extraction pressure. it was also...

Three different methods, including Soxhlet, traditional and screw press, were used to extract oil from African pear pulp. The oils analysed for selected minerals phytonutrients; stored 4 weeks oxidative changes. micro-components results ranged 0.00 41.50% chlorophyll, 1.25 µg/100g total carotenoids, 0.02 0.04 mg/100g iron, 0.01 copper, 18.25 208.50 vitamin E. stability showed that peroxide valu...

are certain that a number of synthetic chemicals act like hormones (e.g. estrogen) and interact with the human hormone system. Scientists also agree that the magnitude of the problem (including human exposure) is uncertain. Therefore, the analysis of phenols in natural wastewater and soils is of prime importance to environmental organizations due to their frequent occurrence in a wide range of ...

Abstract Bark on trees protects the plant against environmentally adverse conditions as well fungi and insect attacks. There are different chemical substances, mostly in outer bark of trees, which can stop from developing. a by-product wood plantations is available high quantity serve an excellent source for production eco-fungicides. In presented article, various poplar clones two short-rotati...

Extractions of a polycyclic aromatic hydrocarbon (PAH)-contaminated soil from a former manufactured gas plant site were performed with a Soxhlet apparatus (18 h), by pressurized liquid extraction (PLE) (50 min at 100 degrees C), supercritical fluid extraction (SFE) (1 h at 150 degrees C with pure CO2), and subcritical water (1 h at 250 degrees C, or 30 min at 300 degrees C). Although minor diff...

There are many reports on biological activities of pentacyclic triterpenoids, which could be relevant to the pharmacological effects including anti-inflammatory properties. Dandelion (Taraxacum officinale Wiggers et Weber, Asteraceae) is one of the best known European medicinal plants, rich in triterpenoids, which has been used for the treatment of various inflammatory diseases such as rheumato...
