“…Beyond this maximum point, the fixed oil extracted plummeted resulting in the reduction of energy dissipation (Mihaela and Simona, 2007). This suggests that with an increase in solvent volume, most of the microwave energy emitted goes into the vaporization of the large volume of water as reported by Desai and Parikh (2012).…”

Black and white peppers are functional crops, used in food industries as spice and in traditional medicine, for the treatment of many degenerative diseases. This study investigated the influence of microwave heating on the extraction yield, energy absorption and dietary elemental composition of oleoresin extracts from black and white pepper. Under the largest donating rule, the maximum extract yield obtained was 48.22 mg/g from black pepper and 79.02 mg/g from white pepper microwave. The study therefore elucidated the energy absorption capacities in microwave heating and itsresultant effects on extraction yield. This clearly showed the potentials of microwave technology in obtaining high quality extracts with properly controlled parameters.

“…Its applications in Nigeria include cures for upset stomach, malaria therapy, insect repellent and as an antioxidant (tea) [8]. C. citratus and C. flexuosus are the prevailing species in Eastern and Western India and have been used locally in cosmetics, insecticides, and for the treatment of digestive disorders and fevers [9,10]. …”

Abstract:Cymbopogon genus is a member of the family of Gramineae which are herbs known worldwide for their high essential oil content. They are widely distributed across all continents where they are used for various purposes. The commercial and medicinal uses of the various species of Cymbopogon are well documented. Ethnopharmacology evidence shows that they possess a wide array of properties that justifies their use for pest control, in cosmetics and as anti-inflammation agents. These plants may also hold promise as potent anti-tumor and chemopreventive drugs. The chemo-types from this genus have been used as biomarkers for their identification and classification. Pharmacological applications of Cymbopogon citratus are well exploited, though studies show that other species may also useful pharmaceutically. Hence this literature review intends to discuss these species and explore their potential economic importance.

“…Higher extraction of polyphenolic compounds was observed, when solvent polarity was modified by addition of water in the solvent [22]. Microwave extraction shows promising advantages over conventional solvent extraction system and is an efficient method for Downloaded by [University of Connecticut] at 03: 22 13 April 2015 A c c e p t e d M a n u s c r i p t 4 extracting active biological compounds [23,24,25,26,27,28]. Polyphenolic compounds from waste Cherry Pomace [29] grape seeds [22] and tea leaves [21] have also been successfully extracted by MAE technique.…”

The process of microwave assisted extraction of antioxidants extract from Garcinia pedunculata Robx. was optimized using response surface methodology. A Box-Behnkem design was used to investigate the effects of three independent variables, namely solvent concentration(%), solvent to sample ratio(v/w) and radiation time(min) on total antioxidant activity by DPPH and ABTS radical scavenging activity. Optimal conditions for extraction of antioxidants concluded that the solvent concentration be 70.79%, solvent to sample ratio be 20:1 and irradiation time at 4.73 minutes. However, the antioxidant activity of extract was found to reach upto 85.98% DPPH radical scavenging activity and 19.23 mg-trolox equivalent/g dry weight. FTIR study revealed that, the extraction of antioxidant extract was higher with increase in irradiation time, but antioxidant activity of extract was lower with increase in time. The structural changes in plant material after extractions observed by light microscopy provided visual evidence of the disruption effect.
