The chlorophyll extracted by 90% acetone was higher than that extracted by Chlorophyll b Young leaf Total chlorophyll = a+b Young leaf Chlorophyll a Adult leaf Chlorophyll b Adult leaf Total chlorophyll = a+b Adult leaf Azadirecta indica Neem 5.9431 9.1842 15.1273 13.674 19.486 33.145 Hibiscus rosa sinensis Jaswand 4.3733 6.7405 11.138 6.5964 4.2448 10.8412 Additional modifications to the equations have also been developed so as to permit an estimate of total … these give at best only an estimation of the total chlorophyll a content. • Chlorophyll a is used to indicate the state of fertilisation of a water body.
