Curcumin, a dietary phytochemical, has been extracted from rhizomes of Curcuma amada using ultrasound assisted extraction (UAE) and the results compared with the conventional extraction approach to establish the process intensification benefits. The effect of operating parameters such as type of solvent, extraction time, extraction temperature, solid to solvent ratio, particle size and ultrasonic power on the extraction yield have been investigated in details for the approach UAE. The maximum extraction yield as 72% was obtained in 1 h under optimized conditions of 35 degrees C temperature, solid to solvent ratio of 1:25, particle size of 0.09 mm, ultrasonic power of 250 W and ultrasound frequency of 22 kHz with ethanol as the solvent. The obtained yield was significantly higher as compared to the batch extraction where only about 62% yield was achieved in 8 h of treatment. Peleg's model was used to describe the kinetics of UAE and the model showed a good agreement with the experimental results. Overall, ultrasound has been established to be a green process for extraction of curcumin with benefits of reduction in time as compared to batch extraction and the operating temperature as compared to Soxhlet extraction.

Plants are one of the most important sources of medicines. Syzygium cumini known as “jamun” in Hindi which is found in throughout India. The leaves are having promising therapeutic value with its various phyto constituents such as tannin, alkaloids, flavonoids, terpenoids, fatty acid, phenol, minerals, carbohydrates, and vitamins. All these phyto constituents are analyzed by qualitative analysis method. Betulinic acid is a naturally occurring pentacyclic triterpenoid compound. The medicinal application of betulinic acid is available for diabetes, cancer cell, and HIV. Betulinic acid shows more solubility for methanol. For extraction of betulinic acid, different extraction techniques like batch extraction and Soxhlet extraction techniques are used. The effect of various parameters like particle size, agitations speed, temperature, and solid loading is studied. To explain the extraction of biological material from plant sources different model equations are used which describes sorption isotherms of material. The experimental data of solid loading and temperature are best fitted by using second order Peleg’s model. From this model the linearized Arrhenius equation was obtained and temperature dependency was 0.567 kJ/mol. The aim of this study is to find out the best kinetic model for extraction and experimental data shows the good agreement of betulinic acid with methanol which justifies batch extraction process.

In the present study, press mud, a sugar industry waste, was explored for biobutanol production to strengthen agricultural economy. The fermentative production of biobutanol was investigated via series of steps, viz. characterization, drying, acid hydrolysis, detoxification, and fermentation. Press mud contains an adequate amount of cellulose (22.3%) and hemicellulose (21.67%) on dry basis, and hence, it can be utilized for further acetone-butanol-ethanol (ABE) production. Drying experiments were conducted in the temperature range of 60–120 °C to circumvent microbial spoilage and enhance storability of press mud. Furthermore, acidic pretreatment variables, viz. sulfuric acid concentration, solid to liquid ratio, and time, were optimized using response surface methodology. The corresponding values were found to be 1.5% (v/v), 1:5 g/mL, and 15 min, respectively. In addition, detoxification studies were also conducted using activated charcoal, which removed almost 93–97% phenolics and around 98% furans, which are toxic to microorganisms during fermentation. Finally, the batch fermentation of detoxified press mud slurry (the sample dried at 100 °C and pretreated) using Clostridium acetobutylicum NRRL B-527 resulted in a higher butanol production of 4.43 g/L with a total ABE of 6.69 g/L. © 2017 Springer Science+Business Media New York Author keywords
