R. multiflora (Fig.1. e. clove-like spicy fragrance, far-reaching sweet fragrance)....
.....eugenol (16.1%), geraniol (2.3%), geranyl acetate (8.7%), 2-phenylethanol (34.7%) and 2- phenylehtyl acetate (7.8%) in R. multiflora ....
The main component of the fragrances of the following three roses: R. multiflora, R. multiflora var. adenochaeta, and R. onoei, was 2-phenylethanol, which we consider is responsible for their sweet fragrances. We classified these roses into one “Multiflora-like group”. Our analysis had revealed that eugenol is contained in the fragrance of R. multiflora. Eugenol adds the spicy note to the fragrance of R. multiflora, while many other components contribute to the deep and sophisticated feel to it......We have further ascertained that the R. moschata, which has been used in producing perfumes in some countries in the Middle East, showed a close similarity to R. multiflora in that its fragrance had eugenol as well as 2-phenylethanol among its main components (Table2).....
In an attempt to ascertain whether or not plants of the same species growing in different habitats may reveal different fragrance compositions, we made a comparative study of the fragrances obtained from R. multiflora plants in the habitats in Kisarazu, in Inba Pond area, and in Akita, and those from R. rugosa plants in their habitats in Niigata and in Hokkaido (Table 4). The result was that there was hardly any difference in the substances composing their fragrances, though some slight difference was found in their ratios.....
We also tried to ascertain the change in fragrances according to the time of day. We analysed the fragrances of R. multiflora collected at different times of day (Fig.4). From the olfactory point of view, it was felt that the fragrance weakened as time passed. Among the main components of its fragrance – eugenol, geraniol, geranyl acetate, 2-phenylethanol – geraniol and geranyl acetate were lost toward the evening, but the ratio of 2-phenylethanol stayed the same, and as for eugenol, its ratio even tended to increase. It was supposed that eugenol largely contributed to the quality of the fragrance this rose emitted in the evening (Table 5). Actually we had an impression that the diffusive quality we felt in the morning in the fragrance of this species was lost in the evening.

Rosa multiflora Thunb.

Habitat : Cultivated in Kulu. Occasionally found in hedges and abandoned coffee plantations in Upper Ghats.

[Name in] Ayurvedic : Rakta-Taruni (nonclassical).
Folk : Gulaab.

Action : Fruit—antiseptic,applied to wounds,injuries,sprains and foul ulcers.The fruit yielded beta-sitosterol,scoparone,salicylic and gallic acid. Fruits contained multiflorin; flower petals gave astragalin. A purgative compound, multinoside Aacetate, has been isolated from the fruit. Quercetin-3-O-xyloside, isoquercitrin and hyperin were also isolated. Floral absolute oil contains eugenol (22.8), phenylethanol (18.1) and heneicosane (10.2%). The root gave a triterpenoid, tormentic acid.
The plant extract, along with kojic acid or its derivatives, produced excellent skin-lightening and sun-burn preventing effects

No-Ibara (Field Briar) R. multiflora Thunb. var. multiflora (syn. =R. polyantha Siebold et Zucc.)
Murray. Syst. Veg. ed. 14:474 (1784)
Distribution: SW-Hokkaido, Honshu, Shikoku, and Kyushu
R. multiflora grows naturally in many parts of Japan. Among the white-flowered wild roses growing in this country, only this rose has no pubescence on the surface of its united styles of pistils, so it is easy to determine its identity if we examine the flower with a magnifying glass. As its epithet indicates, the feature of R. multiflora is its big panicles with many flowers. However, there are a considerable number of local variations. In general, those found in northern areas, especially those in the Tohoku district on the Sea of Japan side, bear large flowers and inflorescences, which gradually become smaller in size as we come down to southern areas. The average size of the flower is between 1.8 and 2.3 cm across. Even smaller flowers we find in southern areas give off a wonderful sweet fragrance...
This is the rose famous for the roles it played as the ancestor of many cultivated roses, such as Multiflora Ramblers, Polyanthas, and Floribundas. It is also very familiar to us as commonly used rootstock in Japan. Fruits of R. multiflora are called 'Ei-jitsu', and have been used in traditional Chinese medicine for their strong diuretic effects.
