SUN PROTECTIVE ACTIVITY OF Clitoria Ternata Linn, Canna Indica Linn FLOWER
... extract INTRODUCTION Sun is the source of energy for all forms of life on earth. Sun shade helps in the synthesis of vitamin D in turn promotes proper growth of bones by synthesizing calcium. As we know skin is the outermost organ of the body and so it is easily affected by the UV rays from the sun. Sun rays are the most harmful factor that affects skin and causes sunburns, ... time the longer wavelength of UVB and UVA pass right through the atmosphere. The molecules in sunscreen absorb most UVB and prevent it from reaching the skin just as the molecules of the atmosphere absorb UVC and prevent it from reaching the ground. Exposed sun ultraviolet light classify in to 3 types, by its wavelengths: UVA, UVB and UVC. The dimensions ... spathulate, 1 linear revolute. In the gold coast, the flowers are said to cure eye disease.  Knowingly or unknowingly there is a sun protective activity in the daily food that we eat. This can be use as an alternative to commercial sunscreens. Some of the food that helps us from UV rays is as follows Tomato paste, Olive oil, Cabbage, Broccoli, Grape skins, Mustard
