| Abstract | ||
| Local henna leaves, which belong to the speices Lawsonia inermis was subjected to chemical and biological studies. The chemical studies include the quantitative and qualitative analysis of the active and essential components. The percentages of the essential of the leaves are as follows: 7.22% moisture, 15.78% protein, 25.1% carbohydrates, 8.2% fats, 4.2% fiber and 13.18% total ash that include 33.44 mg/g water soluble ash and 23.73 mg/g acid insoluble ash. It was also found that fatty acids content of the henna leaves include the following free fatty acids: caprylic trace, capric trace, lauric 0.42%, Myristic 1.33%, palmitic 16.20%, stearic 2.43% oleic 15.37%, linoleic 45.73%, linoleneic 17.86% and arachidic 0.66%. The other part of the chemical study includes isolation of lawsone, the active substance of henna leaves which is identified as 2-hydroxy– 1,4-naphthoquinone by melting point, infrared spectra, ultraviolet and visible spectra and thin layer chromatography. | ||
