The present study aims to examine the antibacterial compounds of the moso bamboo shoot skin. However, the active compounds remain unclear. pubescens) and its dichloromethane extract show antibacterial activity against S. Previously, we reported that the shoot skin of a bamboo species ( P. It is essential to utilize bamboo shoot skins efficiently. These skins are often composted, but they decompose slowly, so most bamboo shoot skins are burned. A lot of food and food ingredients are produced from bamboo shoots, and bamboo shoot skin is a large by product of food processing. Fukuoka prefecture is the major cultivation area of bamboo shoots in Japan. For example, bamboo shoot skin is used as a preservative container to maintain the quality of tea leaves in China and has been used to wrap rice balls and meats in Japan. The present study focused on moso bamboo shoot skins ( Phyllostachys pubescens), which have been traditionally used for packaging food. Tricin and taxifolin, found in the bamboo sheath, reportedly have antioxidant activity. In addition, 2,6-dimethoxy- p-benzoquinone obtained from the skin of the bamboo was found to have antibiotic activities, as were two chitin-binding peptides: Pp-AMP1 and Pp-AMP2, that were isolated from bamboo shoots. In these studies, various active compounds were separated from the leaves, such as flavones, glycosides, phenolic acids, coumarin lactones, anthraquinones, and amino acids. Studies have also revealed that bamboo leaves have antioxidant, anticancer and antibiotic properties. For example, its roots and leaves have been used medicinally. Research into natural products that can prevent the growth of bacteria in foods has been underway in many laboratories.īamboo is well known for its usefulness. Because they grow in foods, it is important to prevent their growth in foods. These toxins cause abdominal pain, vomiting, and diarrhea. They produce several toxins such as enterotoxin-A and -D. These bacteria live on human skin and infect the body through wounds or foods. Staphylococcus aureus is a major food pathogen. Hence, the emergence of materials having less harmful effects and preferably natural material would be highly desirable if their safety to consumers could be guaranteed. This has led to popular movements to reduce the use of synthetic chemical compounds in foods and cosmetics. Meanwhile, consumer demand to ensure that only safe additives are used is increasing every year. Despite this, such additives are still used as preservatives in foods, cosmetics, and medical products. Recently, chemical food additives such as paraben have been reported to have harmful effects.
