To confer hydrophobic properties to Kraft pulp, an environmentally friendly process using laccase and lauryl gallate (LG) was developed. This treatment resulted in paper with very high water-barrier properties. The loss of hydrophobicity after acetone Soxhlet extraction highlighted the key role of adsorption phenomena on the introduction of pulp properties. GC-FID analysis of the extraction sup...

Abstract Medicinal herbs have a long history of use in improving human health and curing diseases. Herbal materials are naturally an excellent medicine library because they provide unlimited components with complex chemical structures and a wide range of bioactivities. Herbal materials have thus attracted wide interest of researchers in the identification of the active components and verificati...

The complexity of sample matrices, coexistence of multiple forms of bioactive phytochemicals, and their interaction of with other cellular components pose a significant challenge for optimized extraction and accurate estimation of bioactive phytochemicals in foods and dietary supplements. This article discusses the significance of optimizing extraction procedures for accurate assay of phytochem...

Carduus nutans L. is a biennial plant which is belonging to Asteraceae family known as musk or nodding thistle commonly. Carduus species includes different active ingredients like essential oil, resin, tannin, fatty oil, starch, flavonolignans, polyacetylenes. Importance of phytochemistry and chemical ecology researches increase gradually. The fat extraction was carried out by Soxhlet method wi...

Nicotiana tabacum commonly known as Tobacco plant which has broad application over soap, paint and cigar industries was now investigated for biodiesel production. Nicotiana tabacum seeds were one of the prominent sources for non-edible oil. Oil from Tobacco seeds were expelled with Soxhlet extraction apparatus using n-hexane as extraction solvent. Two stage trans-esterification has been adopted...

Optimization of extraction conditions and phytochemical screening of the root bark of Synadenium glaucescens were carried out in a stepwise manner in order to obtain the highest yields and the constituents of the extracts. Sequential extraction using Soxhlet method was performed using dichloromethane, hexane and petroleum ether, respectively, each followed by ethanol. Extraction conditions incl...

Pomegranate seed oil was extracted in a closed-vessel high-pressure microwave system. The characteristics of the obtained oil, such as fatty acid composition, free fatty acidity, total phenolic content, antioxidant activity and colour, were compared to those of the oil obtained by cold solvent extraction. Response surface methodology was applied to optimise extraction conditions: power (176-300...

Present work investigated an apposite and efficient method for extraction of betulinic acid (BA) from the bark of Ziziphus jujubae. Various extraction methods like stirring extraction, soxhlet extraction, ultrasonic extraction, and microwave assisted extraction (MAE) were evaluated for increasing recovery percentage of BA. From the raffinate so obtained, BA was isolated. Thin layer chromatograp...
