RESUMEN
This study compares the proximate composition, mineral composition and the presence of antinutritional elements of Zea mays with the seeds of four selected tropical plants which include Gmelina arborea, Terminalia catappa, Dacroydes edulis and Delonix regia. The matured fruits of the test materials were collected from farmlands in Asaba, Delta State Nigeria (6014’N and 6049’E). The seeds were carefully removed from the matured fruits and proximate analysis carried out to determine the levels of crude protein, crude fiber, energy, total ash and ether extract. The presence of the following mineral elements: calcium, magnesium, potassium, sodium, iron and zinc was determined. The presence of alkaloids and oxalate, which are anti-nutritional elements, was also determined. Significantly different means were separated using Duncan’s multiple range procedure. Significance was reported at 5% level of probability. Significant differences between the test materials were observed for all parameters measured.
RESUMEN
OBJECTIVE:To analyze the effects of environmental factors (soil,climate,etc.) on the quality of Radix Polygalae.METHODS:The contents of polygalic acid were determined by HPLC.Climate factors including altitude,average annual temperature,average temperature of July,annual precipitation,annual sunshine hours and non-frost days were collected through on-site inspection or from the local meteorological data. Water content,pH and nutritional elements of the soils were determined by routine method,and the reletionship between the content of polygalic acid and the factors were analyzed.RESULTS:There was linear relationship between the content of polygalic acid and climate factors such as average temperature of July,annual precipitation,annual sunshine hours and non-frost days.There was also linear relationship between polygalic acid and soil factors such as total nitrogen,total phosphor,available phosphor,available kalium,organic matters and water content. CONCLUSION:The main climate factors that affect polygalic acid content were annual sunshine hours and non-frost days,while the main soil factors affecting the content of polygalic acid were the content of available phosphor and soil water content.
