animal tissue sample preparation, focusing on quantitative bioanalytical applications. However, we will not cover applications for microscopy, imaging and elemental analysis. We will also not cover the preparation of plant samples, because plant tissues are very different in structure and physical content from animal tissues.
When each plant has been sampled and the tubes are ready. 2.0 ml of Sample Extract / Grinding Buffer (Appendix 3) is pipetted into each of the test tubes for Phaseolus and Pisum, 6 ml for Lactuca. Samples are ground for 3 - 5 sec each with a homogenizer (Brickmann Polytron). Between samples the bit is rinsed 3 times.

Extraction is the separation of medicinally active portions of plant using selective solvents through standard procedures. Various methods, such as Maceration, Infusion, Percolation, Decoction, Digestion, Soxhlet extraction, Microwave assisted extraction, Ultrasound-assisted extraction, Accelerated solvent extraction and Supercritical fluid extraction are used …
Cryogenic grinding is a very effective technique for taking hard substances, like plant and animal tissues, and turning them into dust. The tough carbohydrates of plant tissues become very fragile at -196°C and easily shatter. The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low.
of plant samples to preserve the biomolecules in the plants prior to extraction. Plants samples such as leaves, barks, roots, fruits and flowers can be extracted from fresh or dried plants material. Other pre-preparation of plant materials such as grinding and drying also influences the preservation of phytochemicals in the final extracts.

Grinding Hemp. Grinding substantially increases the surface area of the hemp plant. As a result, supercritical carbon dioxide gets more surface area to act on. Such action delivers higher extraction yields [7]. Plant materials have low packing density. This limits the quantity of material personnel can load into the extractor of the SCFE system.
