The general trends found in Saxony for the harvested plants could be confi rmed. Interestingly, the overall yield after the fi rst year remained almost constant with all plants, but there is a strong dependency on the triterpene content with harvest time. The fi rst cut in June contains mainly monoterpenes and can be further processed for tea, spice etc. The second cut in September shows an increased triterpene content (maximum here for both acids is about 6%) and even better results could be achieved if the plant is under a poly - tunnel

complete production chain and importance: natural products
BY AAP Bridge at AAPBridge
The production chain with natural products has three major parts to consider. The
fi rst is agricultural, followed by, for example, extraction to get a concentrated
raw extract, and in pharmaceutical applications (not with cosmetics and nutraceuticals) a fi nal purifi cation step is necessary in order to get an ultrapure product
To highlight the importance of including the complete production chain, we
can consider growing a crop of plants containing oleanoic acid. This is found in
several plants (almond hulls, privet, rosemary, thyme, clove, lavender, olive, hawthorn, periwinkle etc.) with a content less than 1% in dry mass. Higher values
were observed only with a different kind of sage. The value varies with location
and local climate (e.g., Germany versus Greece), types of soil (sandy, thus irrigation needed), distance between the growing rows and cultivar. With the latter,
higher content is with plants from scions obtained through vegetative reproduction ( Salvia offi cinalis ) compared with those from sowing ( S. lavendulifolia ).
However, planting with scions is very labor - intensive, which has quite an impact
in respect to labor costs, and sowing is then the alternative. Optimal conditions
for sage are with warm and wind - protected sites, with a light soil containing
compost and water. Dry periods are no major problem and the plants should
grow in rows (distance 25 – 50 cm) as depicted in Figure 1.7 [15] . Usually, the
useful life is four to fi ve years and for soil recovery a four - year interval is recommended. If the plants are used to gain pharmaceutical extracts, all cultivation steps
(sowing, manuring etc.) must be documented and with pest management any
pesticide (date, dosage etc.) must be registered. With sage the use of herbicides is
forbidden and two cuts per year are recommended
