Identification of Fungi Associated With the Spoilage of Sweet Potato Tubers Sold at Ogbete Main Market in Enugu, Enugu North Local Government Area. Enugu State
CHAPTER ONE
OBJECTIVES OF THE STUDY
The objectives of this study seek to establish the quantitative determination of phytochemical constituent of Ipomoea batatas.
CHAPTER TWO
LITERATURE REVIEW
MEDICINAL PLANT
About half the worlds medicinal components are still derived or obtained from plants and other biota are, in general more important in developing countries than in industrialized nation. But even in these, where the focus is very much on chemical discovery and synthesis of pharmaceutical, drug products from biota are major contributors to the human health services sectors of the economy, and plant derived drugs contributed to the economy each year.
It is also noteworthy that some of the most important drugs of the past 50 years or so, which have revolutionized modern medical practices, have almost all first been isolated from plants and often from plants which for one purpose or another have been employed in primitive or ancient societies (schulkes 1986). These wonder drugs include the curare altraloids; penicillin and other antibiotics; cortisone, reserpine; vincoleublastine, the vetratrum alkaloid podophyllotoxin; strophantine and other new therapeutically agent (Schulkes and Swain 1976).

MATERIAL AND METHODOLOGY
MATERIALS/REAGENTS
Ipomoea batatas (confiffetti tee),Automated pipette, Beaker, Buchner funnel, Volumetric flask ,Reflux condenser, Whatman paper, Spectrophotometer, Conical flask, Separating funnel, Water bath, watch.
REAGENTS
Methanol, Parafilm, Alcohol, 10% of Hcl, Mgo, Sucrose, Conc.H2SO4, Selenium, Isobutyl Alcohol, Benzene.
COLLECTION OF PLANT SPECIMENS
The stem of Ipomoea batatas was collected from a tree along Lemu road near Bida town Niger state. The stem was identified and authenticated by a botanist in biology unit of The Department of Science Laboratory Technology, The Federal Polytechnic Bida Niger, State.

CHAPTER FIVE
CONCLUSION AND RECOMMENDATION
CONCLUSION
The result of the work done supports the facts that the medicinal plants possess various active compounds or substances which are useful for therapeutic purpose and has effect against some diseases.
The quantitative screening of aqueous extract of Ipomoea batatas could help, this might account for the reasons why they (i:e medicinal plant) are used for treatment of diseases.
RECOMMENDATION
- Research institution should focus their attention on rural areas for medicinal plants, since they are more abundant there and possible load for a very way of conserving this medicinal plant in a garden.
- More antimicrobial testing should be conducted using different test organisms especially clinical isolated organisms since the plant show significant activity against the organisms used.
- Further more investigation on the plant Ipomoea batatas is also imperative. This investigation includes antimicrobial properties of Ipomoea batatas.
- It is recommended that effects should be geared towards extraction of aqueous extract of antimicrobial substances from plant origin, so that toxicity associated with synthetic antimicrobial substances could be reduced or if possible eliminated
