The second example described here is dormant seeds from Rosa canina. Extracts of these seeds also inhibit germination of seeds of several plants (10). In Figure 5 a scheme is given for extraction and separation oF"three different inhibitor compounds. All these are present in the acid fraction. The first essential step is chromatography on Sephadex LH-20, which separates inhibitor I from inhibitor II and III. Inhibitor I was identified as abscisic acid. The other two inhibitors were separated by methylation with diazomethane, fractional distillation, and column chromatography. The second inhibitor is the a-pyrone 1 . Reaction with diazomethane transforms it into the bi-cyclic compound 19. This bicyclic compound is even more active than the parent a-pyrone 1 . Since we sought structural requirements for bioactivity here also,we tested several synthetic a-pyrones ( 0 - 22) for bioactivity. These compounds had no inhibitory activity. We alio tested the cyclopropane derivatives 23 and 24 In Table II, the bioactivity of the bicyclic compound T9 and two such derivatives is compared. The presence of several carboxylic acid groups seems to be essential (or at least helpful) for bioactivity in this case also.

The complexity of the aqueous products situation can be illustrated by Rose Water. It is a long established product with a history of applications in cosmetics, skincare and culinary preparations. Initially it may be produced from different botanical species e.g. typically Wild rose (Rosa canina), Damask rose (Rosa damascena) and Cabbage rose (Rosa centifolia). 

Rose, Rosa canina L., also known as dogberry or hop fruit, is in the Rosaceae family. The fruit of this particular species of rose is generally used to prepare a stew. The seeds from Rosa canina L. were investigated for their chemical composition and nutritional values for medicinal purposes. Seed oils were prepared from fruits grown at three locations in Turkey and evaluated for their fatty acid composition (31). Linoleic acid was the primary fatty acid detected, which ranged from 48.6-54.4% of total fatty acids, followed by a-linolenic acid (16.4-18.4%) and oleic acid (14.7-18.4%) (Table 4). The seed oil contained approximately 85% total unsaturated fatty acids, indicating that Rosa canina L. seed oil may be an excellent source for unsaturated and essential fatty acids.

Hvattum [48] reported the analysis of varions phenolic compounds in Rosa canina using LC-DAD, negative-ion LC-ESI-MS, MS-MS on [M-H] , and MS-MS on fragments generated by in-source CID. In this way, the aglycones catechin and quercetin, and various glycosides of quercetin, taxifolin, and eriodictyol were identified as well as some other plant phenol compounds. 

Rose proliferation and stunting as well as rose leaf curl and shoot dieback symptoms in rose cultivars were associated with aster yellows phytoplasmas (AY, 16SrI-B). It was also found, that two rose cultivars, with shoot proliferation or flower proliferation symptoms were infected by phytoplasma classified to apple proliferation group (16SrX-A) (Kaminska and Sliwa, 2004). Jarausch et al. (2001) reported the occurrence of European stone fruit yellows phytoplasma (16SrX-B), Candidatus phytoplasma prunorum and rubus stunt (16SrV-E), in asymptomatic Rosa canina plants surrounding peach orchards. 

Rose hip, Cynosbati fructus, is the dried flower bottom of Rosa canina L., family Ro-saceae, deprived of the hairy fruits ( kernels ) from the inside of the drug. The drug contains at least 1% ascorbic acid, and also carotenoids and flavonoids with vitamin P-ef-fect. Rose hips are still used as a vitamin C source in vitamin preparations.

Polysaccharides.—This research is centered around 1900. Many pectins were isolated from various plants gentian, red currant, and Rosa canina. Bourquelot and H issey were among the first to point out that natural macromolecules, while possessing certain general properties in common, differ nevertheless from one species to another in their degree of complexity. Plant pectins could be differentiated from one another by optical rotation, but all produced, on hydrolysis, L-arabinose and n-galac-tose. 

It is well known that the distribution of the chemical elements in a plant is relevant to its physiology, to its defense against parasites and herbivores, to the element s entry into food chains, etc. Perennial herbs (A. ageratum, I. viscosa, S. vulgaris, Reichardia picroides, H. perforatum) or woody species (Ulmus minor, Cistus salvifolius, Rosa canina) concentrate antimony in epigeal parts which are lost at the end of the growing season. In this way, these plants rid themselves each year of part of the absorbed... 

The botanical characteristics of roses bear considerable relevance to their historic importance. The earliest three roses, from which all other roses are derived, are the Rosa caninae, which is the five petal dog rose, Rosa gallicanae, also called the gallica rose, and the musk rose Rosa sysnstylane. 

The dog rose, Rosa caninae is associated with the Dog Star Sirius, which is the brightest star in the sky. It represents the love of Venus, Ishtar and Isis. The five white petals are symbols of virginity. They are also the pentagon traced out in the night sky by the planet Venus in its eight-year cycle. In Zoroastrian tradition, the dog rose also stands for the illumination of love. In contrast, a red rose represents the womb, its menstrual blood and the ardor of carnal love. It S5mibolizes the bloom of puberty.
