نبذة مختصرة
A few years ago, an extraction method with 80% acetone was commonly used. However Porra et al (1989) showed that the extraction of chlorophyll b with 80%acetone is not complete. In the calculations, chlorophyll b is underestimated, resulting in a higher chlorophyll a-b ratio (>4.00). With methanol, chlorophyll b is extracted completely, resulting in a better determination of the chlorophyll a:bratio. All preparations should be done as cold, as quickly and as dark as possible. Chlorophyll disintegrates due to warmth and light.A few years ago, an extraction method with 80% acetone was commonly used. However Porra et al (1989) showed
