PARMAR JF - LIFE SCIENCES LEAFLETS JA - LSL VL - 118 IS - 0 SE - Research Paper DO - UR - https://petsd.org/ojs/index.php/lifesciencesleaflets/article/view/1456 SP - 15 TO 18 AB - <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>&nbsp;<em>baccifera</em>&nbsp;L.<em>, Eichhornia</em>&nbsp;<em>crassipes</em>&nbsp;(Mart.) Solms<em>, Hydrilla</em>&nbsp;<em>verticillata</em>&nbsp;(L.f.)Royle<em>, Nymphaea</em>&nbsp;<em>pubescens</em>&nbsp;Willd, <em>Bacopa</em>&nbsp;<em>monnieri</em>&nbsp;(L.) Wettst. and <em>Typha</em>&nbsp;<em>angustifolia</em>&nbsp;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>&nbsp;<em>pubescens</em>&nbsp;than other Aquatic plants.</p><p>&nbsp;</p> ER -
