In a study by Karim‚ Asma and Kamal et al.‚ (2016) in vitro antimicrobial activity of Sudanese Cucumis melo L. fixed oil was investigated. Agar cup diffusion assay was performed against two fungal species (Candida albicans and Aspergillus niger)‚ two gram positive bacteria (Staphylococcus aureus and Bacillus subtilis) and two gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa).

She found that all the plain jelly set as usual‚ but jelly with fresh pineapple and fresh kiwi added failed to set. She was intrigued by this observation and she asked Miss Chan‚ her biology teacher‚ about it. Instead of telling Mary the answer directly‚ Miss Chan provided her with a piece of useful information: “Jelly contains a kind of protein called gelatin‚ which causes the jelly solution

Many of these rod-shaped asci‚ each with eight ascospores‚ are held together in a protective‚ flask-shaped perithecium. In agar cultures‚ the perithecium‚ about 0.5 mm high‚ has its lower part immersed in the jelly with its neck projecting into the air (Figure 1). The perithecium opens to the outside by a narrow canal through which only one ascus can extend at a time. The ascospores are actively discharged into

REVIEW OF RELATED LITERATURE This investigatory project aims to make use of rambutan peeling extracts that is high in phenolic compounds such as tannin and saponin that exhibits antioxidant activity and antibacterial activity against pathogenic bacteria. Although the seeds contain such compounds the peeling exhibit greater amount of the said compounds. Rambutan is a very popular fruit cultivated in the Philippines and it is eaten in large amounts. The rambutans rind is quickly discarded and

Chapter One INTRODUCTION Herbal medicines tend to look primitive and unscientific when compared to synthetic (conventional) drugs‚ which are thought to be more reliable than those made from plants. Herbal medicine is still the mainstay of about 75-80% of the world population‚ mainly in the developing countries for primary health care (Kamboj‚ 2000). This is primarily because of the general belief that herbal drugs are without any side effects‚ besides being cheap and locally available. The
