PARMAR}, volume={118}, url={https://petsd.org/ojs/index.php/lifesciencesleaflets/article/view/1456}, abstractNote={<p>Chlorophyll a, b, c, d, Carotene, Xanthophylls are present in all higher plants. Then chlorophyll a and b are most important for plants. Make extract of chlorophyll in 80% acetone and estimate by spectrophotometer in Optical Density. Chlorophyll a and b are measured in amount of mg/mL. Chlorophyll is estimate of hydrophytes plants in <em>Ammannia</em> <em>baccifera</em> L.<em>, Eichhornia</em> <em>crassipes</em> (Mart.) Solms<em>, Hydrilla</em> <em>verticillata</em> (L.f.)Royle<em>, Nymphaea</em> <em>pubescens</em> Willd, <em>Bacopa</em> <em>monnieri</em> (L.) Wettst. and <em>Typha</em> <em>angustifolia</em> L. The range of chlorophyll contains are 1.9826 to 6.9220 mg/mL for chlorophyll a and 2.6598 to 10.7774 mg/mL for chlorophyll b<em>. </em>Concentration of chlorophyll a and b was calculated using Arnon method. Chlorophyll content was higher in <em>Nymphaea</em> <em>pubescens</em> than other Aquatic plants.</p> <p> </p>}, journal={LIFE SCIENCES LEAFLETS}, author={PARMAR, Dr.A.J.}, year={2019}, month={Dec.}, pages={15 TO 18} }
