The leaves of Lantana camarawere submitted to preliminary phytochemical study obtaining essential oil and methanolic extract. In the analysis of the essential oil (hydrodistillation), they identified cariophilene (7.3%), Germacrene B (37.5%) and Germacrene D (21.7%) as the most relevant of the nine components obtained. The ethyl acetate (EtOAc) revealed from the partition of the ethanolic extract (EtOH) of the Leaves of L. camara was subjected to filtration and column chromatography (CC) resulted in lavone, unheard of in the species.

A grain dryer that uses charcoal as fuel was constructed. The dryer has three component parts namely: drying chamber, heating chamber and heat exchanger The dimensions of the dryer are; height 124.5cm, breadth 41.5cm and length 51.5cm respectively. The body of dryer was made with mild steel and lagged with paper and cotton material. Drying efficiency of the dryer was 63%, while the average drying rate was 0.12g/sec, with a moisture content reduction of 14.2% over period of 70minutes.

The objective of this study was to determine the sample size needed to analyze physical and chemical characteristics of passion fruit (Passiflora edulis Sims f. flavicarpa Degener) after harvest.Fruits harvested from a one year old orchard were used.

Objetivo: O presente trabalho objetiva avaliar a atividade antibacteriana do monoterpeno (R)-(+)- citronelal contra cepas de Klebsiella pneumoniae. Métodos: Para realizar a atividade antibacteriana utilizou-se a técnica de microdiluição em caldo, obtendo-se a Concentração Inibitória Mínima (CIM) e a Concentração Bactericida Mínima (CBM). O ensaio foi realizado em duplicata, utilizando-se uma placa de 96 poços. As placas foram incubadas a 37ºC durante 24-48 horas. A CIM foi determinada como a menor concentração da substância que inibir o crescimento visível do microrganismo.
