2. Antifungal potential of essential oils from two varieties of Citrus sinensis (lima orange and bahia navel orange) in postharvest control of Rhizopus stolonifer (Ehrenb.: Fr.) Vuill.
Abstract Brazil, the world’s largest citros producer, yields around 19 million tons per year and exports most part of its production as orange juice. Essential oils (EOs) extracted from leaves, fruit and flowers of many species of the genus Citrus have been widely used as the result of their promising bioactivities. The fungus Rhizopus stolonifer (Ehrenb.)

5. Antileishmanial in vitro activity of essential oil from Myrciaria plinioides, a native species from Southern Brazil
In South American folk medicine members of the genus Myrciaria are used for the treatment of malaria, diarrhoea, asthma, inflammation and post-partum uterine cleansing. The aim of this work was to evaluate its antileishmanial properties (in vitro) of essential oil derived from leaves of Myrciaria plinioides D. Legrand, a plant species that is native in South

7. Convection combined microwave drying affect quality of volatile oil compositions and quantity of curcuminoids of turmeric raw material
Abstract The aim of the work was to estimate the quality of some compositions in turmeric volatile oil and quantity of individual and total curcuminoids in turmeric powder dried under different conditions. Effect of convection time (0–30 min) and microwave time (20–60 min) on quality of volatile oil compositions and quantity of curcuminoids were investig

8. OPTIMIZATION OF HIGH-CONCENTRATION TRANS-ANETHOLE PRODUCTION THROUGH HYDRODISTILLATION OF STAR ANISE
Abstract Illicium verum Hook essential oil (EO) is composed mainly of trans-anethole (TA), which has therapeutic potential. The extraction is usually by hydrodistillation, taking long hours, leaving the process costly and product with lower quality. Thus, the present study sought to optimize dehydrated fruit fragmentation by Box-Wilson central composite desi
