TP – Extraction de la chlorophylle brute 🌿🧪 Voici les étapes que j’ai réalisées dans ce Reel : 1️⃣ Broyage des feuilles (épinard, géranium…) dans un mortier avec un peu de sable fin. 2️⃣ Ajout progressif d’alcool tout en continuant à broyer pour solubiliser la chlorophylle. 3️⃣ Filtration pour obtenir une solution alcoolique de chlorophylle brute. 4️⃣ Séchage du papier filtre → apparition de cercles colorés (vert, jaune, orange), révélant différents pigments. 🔬 Objectif : Séparer les pigments
