HARVESTING MEDICINAL PLANTS<br />
• Ways of harvesting <strong>medicinal</strong> <strong>plants</strong><br />
- Mechanized (uncommon in spontaneous flora) with combine, plows, dislocation,<br />
mowers;<br />
- Manual: using sickles, scythes, knives, spades, special combs;<br />
• Harvesting conditions<br />
- Harvesting conditions refer to the meteorological characteristics of the period in<br />
which <strong>plants</strong> are collected: warm weather, no rain, <strong>for</strong> some species there are<br />
mentioned optimal moments such as the dew (rose petals), <strong>and</strong> optimal pheno<br />
phase (the vegetation moment when the plant has the best production <strong>and</strong> quality<br />
potential)<br />
•Quality conditions<br />
- Chemical characterization of <strong>medicinal</strong> <strong>and</strong> <strong>aromatic</strong> <strong>plants</strong>, includes<br />
quantitative determination of chemical compounds responsible <strong>for</strong> the therapeutic<br />
effect: glycosides, alkaloids, volatile oils, etc.<br />
- Biomorphological <strong>and</strong> botanical characterization of species: Caracterizarea<br />
biomorfologica si botanica a speciilor: appearance, color, smell, taste, macro <strong>and</strong><br />
microscopic botanical description, purity (mineral impurities <strong>and</strong> <strong>for</strong>eign bodies).<br />
- Determination of contaminants level (pesticides <strong>and</strong> heavy metals) from <strong>plants</strong>.
