Natural products continue to be a source for the discovery of drugs and drug leads even from ancient period. 80% of drug molecules have been obtained from either natural products or derivatives of the natural product. It has been found that the concept of a single drug for treating single disease may become outdated in the near future and the need of polyherbal formulations, as an alternate remedy is under investigation. Medicinal and aromatic plants contain biologically important phytochemicals, which have known curative properties. They are found as secondary metabolites in plants. Plants also contain certain other compounds that moderate the effects of the active ingredients. Medicinal and aromatic plants have their own contribution toward the treatment of both noncommunicable and communicable diseases. A survey done by the WHO indicates that a majority of the world population tends to use plants for treating diseases. Cancer, the second largest cause of death after cardiovascular disease accounts for about 3500 million people globally. Due to the serious side effects of synthetic chemopreventive agents, research is going onto investigate the nature derived chemopreventive agents. In addition to the plant-derived compounds, marine, and animal resources also play an important role as clinically beneficial anticancer agents with minimal or no toxicity. The best examples for plant-derived compounds include vincristine, vinblastine, irinotecan, etoposide, and paclitaxel; they have a different mode of action against cancer such as interaction with microtubules, inhibition of topoisomerases I or II, alkylation of DNA, and interference with tumor signal transduction. The natural products from marine sources such as bryostatin, squalamine exhibit a significant antimitotic, and anti-angiogenic activities. The benefits of various anticancer drugs derived from natural products are the fact that it can have its effect on cancer cells alone without harming healthy cells, which is unlikely to be the case with other conventional chemotherapeutics. In this review, various natural products and their anticancer properties have been discussed briefly.

Medicinal plants, which are used as drugs to prevent diseases, maintain health or cure diseases, take place in areas such as nutrition, cosmetics, body care, incense or religious ceremonies, while aromatic plants are used in different industrial areas to give fragrance and taste are used. Flora of Turkey has a rich plant diversity. Secondary metabolites such as essential oils, alkaloids, glycosides, saponins etc. are the most basic products of the industry directly or indirectly. The vast majority of medicinal and aromatic plants rich in secondary metabolites exhibit strong biological activity (antioxidant, antibacterial, etc.). Therefore, these secondary metabolites are widely used in the pharmaceutical industry. The most common and practical use of secondary metabolites, which are also used as natural insecticides, is in the form of herbal tea. In recent years, the more side effects of synthetic origin substances, especially the resistance of organisms against synthetic drugs used as antimicrobials, have increased the importance of natural herbal resources and medicinal plants carrying these substances. Therefore, there is no doubt that the demand for secondary metabolites, which are natural products, will increase in the future. Flora of Turkey is an important source for natural products which will be developed newly.

Abstract This work refers to the native species of genus Astragalus L. (A. dasyanthus, A. ponticus), Adonis L. (A. vernalis, A. wolgensis) and Digitalis L. (D. lanata, D. grandiflora). The plants are cultivated in the Botanical Garden of Moldova in the field collection of the medicinal and aromatic plants. Investigation includes propagation aspects, research into cultivation techniques and conservation measures. The biological particularities and the phenologic rhythm are also registered. The obtained data shows the ecological flexibility of species and the possibility of preserving them in culture.

AbstractThe environmental benefits of agroforestry systems are well known. However, current knowledge of potential allelopathic interactions is inadequate. The decrease in soil fertility, the increasingly rhapsodic distribution of precipitation, and the special metabolism and cultivation of medicinal and aromatic plants are all harbingers of medicinal-agroforestry systems. The authors aimed to discover the allelopathic effects of Juglans regia L. and Populus tremula L. on germination of medicinal and aromatic plants cultivated in a temperate zone. Accordingly, an in vitro germination trial was conducted with leachates of these trees and two juglone concentrations. These allelopathic effects were evaluated for germination vigour, germination rate, and total fresh weight of seedlings of twelve different species. A pronounced species specificity was observed in tolerance of seeds and seedlings to the allelopathic effect of Populus and Juglans. In four of the species studied, the allelopathic effect may inhibit germination, but only initially. Poppy and angelica proved to be the most sensitive to the treatments. The following species had relative tolerance to the allelochemicals, so further research under natural conditions is suggested for: Althea officinalis L. (9.34 ± 5.04–68.66 ± 13.62 GR%), Anethum graveolens L. (12.00 ± 2.00–100.00 ± 6.12 GR%), Cannabis sativa L. (72.66 ± 9.02–91.34 ± 1.16 GR%), Dracocephalum moldavica L. (38.00 ± 2.00–80.00 ± 17.44 GR%), Linum usitatissimum L. (44.66 ± 2.00–58.00 ± 3.46 GR%), and Satureja hortensis L. (52.00 ± 28.22–82.00 ± 8.00 GR%). The aim would be to introduce them into agroforestry systems.
