The study was conducted to investigate the effect of rootstock on growth and early yield of stenting-propagated cut roses (Rosa hybrida Hort.) 'Pink Aurora' and 'Yellow King'. The scions, prepared as single-node cuttings, each with a five-leaflet leaf, were grafted onto cuttings of Rosa indica 'Major', Rosa multiflora 'Chille Wonye No. 1', Rosa multiflora 'K-1', or Rosa multiflora 'Burr' as the rootstock. The rootstock cuttings were removed of all leaves and buds before grafting. The base of scion and the top of rootstock were held together and simultaneously cut at a $45^{\circ}$ angle for ease of grafting. Scion-rootstock unions were stuck in rockwool cubes and placed on a misted glasshouse bench for rooting before being transplanted into a rockwool slabs for cultivation. Rooting was the greatest in the 'Pink Aurora' and 'Yellow King' grafted on the rootstock Rosa indica 'Major'. In 'Pink Aurora', stem length, stem diameter, five-leaflet leaves per stem, and stem fresh weight of the harvested cut flowers were not affected by the rootstock. The greatest total yield of 'Pink Aurora' was obtained in plants grafted onto the Rosa indica 'Major' rootstock. Overall growth of 'Yellow King' was the greatest in plants grafted onto Rosa multiflora 'Burr' rootstock, although total yield was not affected by the rootstock. These results suggest that Rosa indica 'Major' is the most effective rootstock not only for rooting, but also for early yield and growth for stenting propagation of these cut roses.

In this study, we selected some material to have potential bioactivity from natural plants, confirmed as basic data for industrializing and tried to develope the food materials using them. DPPH, ABTS, antioxidant protection factor, TBARs and antimicrobial activity of extracts from Rosa multiflora Thunberg fruits were determined. The total phenolics extracted from Rosa multiflora were 12.08, 11.82, 11.1 and 12.6 mg/g when using water, 70% ethanol, 70% methanol and 70% acetone as the solvent, respectively. The optimum conditions for extracting the phenolic compounds were 70% ethanol over for 12 hrs(11.82 mg/g). The electron donating ability and inhibition rate on ABTS of the 70% ethanol extracts were 97% and 92.2%, respectively while the antioxidant protection factor(PF) of the water extracts and 70% ethanol extracts were 1.79 and 1.34 PF, respectively. The TBAR (thiobarbituric acid reactive substance) value were $1.3{\mu}M$ for the control and $0.15{\mu}M$ for the 70% ethanol extracts. The inhibitory activity against ${\alpha}$-amylase was 26% for the 70% ethanol extracts. The 70% ethanol extracts from Rosa multiflora Thunberg fruits exhibited antimicrobial activity against H. pylori, S. epidermidis, S. aureusand and E. coli with clear zone diameters of 14, 25, 14 and 13 mm, respectively when using $200{\mu}g/mL$ of the phenolic compounds. An HPLC analysis identified 6 major phenolic metabolites in the Rosa multiflora Thunberg fruits extracts: rosmarinic acid, caffeic acid, chlorogenic acid, courmaric acid, protocatechuic acid and quercetin. In particular, the content of rosmarinic acid was the highest in the 70% ethanol extracts. Therefore these results indicate that 70% ethanol extracts from Rosa multiflora Thunberg fruits can be useful as a natural antioxidant and in functional foods.

The optimum extraction of phenolic compounds from whole Rosa multiflora Thunberg fruits was accomplished using 70% ethanol, which produced extracts that generated a zone of inhibition around Helicobacter pylori of 13 mm when $200{\mu}g/mL$ phenolic compounds were applied. In this study, the quality of white bread baked from dough containing added Rosa multiflora Thunberg extracts was investigated. No deterioration of product quality factors including hydration of wheat flour, formation of dough and internal visual characteristics of dough was observed. However, white bread containing Rosa multiflora Thunberg extracts had a wet texture because of the high moisture level, as well as a high number of irregular bubble holes when compared to the control. Nevertheless, there were no remarkable differences between the sample and the control.

Rosa multiflora thunberg belonging to Rosaceae is widely distributed in East Asia including Korea and Japan, and has been reported to have tormentic acid and rosamultin. To develop a new natural anti-inflammatory agent for cosmetics, we investigated the inhibitory effects of inflammation in Rosa multiflora root (R. multiflora root). The biological activity and anti-inflammatory effects were investigated by water, ethanol, methanol and acetone extracts of R. multiflora root. The measurements of polyphenol content from R. multiflora root were highest in water and acetone extracts, at 57.48 ${\pm}$ 0.88 mg/g and 67.05 ${\pm}$ 0.56 mg/g, respectively. The result of DPPH, ABTS and superoxide anion radical scavenging effects showed over 50% efficacy at 50 ${\mu}g/ml$ in ethanol, methanol and acetone extracts. Hyaluronidase inhibition effect showed over 60% efficacy at 500 ${\mu}g/ml$ in ethanol, methanol, and acetone extracts. Nitric oxide radical inhibition effect of R. multiflora root ethanol extracts showed over 30% efficacy at 500 ${\mu}g/ml$. We investigated the effect of R. multiflora root extracts on nitric oxide (NO) production of inducible nitric oxide synthase (iNOS) in LPS-induced RAW 264.7 macrophage cells. The result showed that R. multiflora root extracts have an inhibitory effect on NO production and iNOS expression and also can be used as an anti-inflammatory agent. These antioxidant and anti-inflammatory effects of R. multiflora root show applicant potential application as a functional cosmetic material.

The Rosa multiflora, a well-known plant belonging to Rosacea, is widely used in orthodox medicine in worldwide. However, its biological activity as a functional ingredient for cosmetic products have not yet been studied. Accordingly, an investigation of the above mentioned atrributes was performed on a 50% ethanol extract of Rosa multiflora. The antioxidant activities were determined by DPPH. Additionally, the contents of total phenols and flavonoids were analyzed. Also, the phenolic compounds were detected using HPLC. The melanogenesis regulatory effect was evaluated using melanin content and cellular tyrosinase activity in B16F10 melanoma cells. The elastase inhibitory activity assay was performed for anti-wrinkle effect. The antimicrobial activity was assessed using the disc diffusion assay. The DPPH radical scavenging ability, denoted by the $SC_{50}$ value was found to be $123.1{\mu}g/ml$, whereas that of positive control (ascorbic acid) was $27.5{\mu}g/mL$. The content of total polyphenol and flavonoid content were 202 mg/g and 86.77 mg/g, respectively. In addition, astragalin and gallic acid were identified in the extract. Also, the ethanol extract significantly inhibited ${\alpha}$-MSH-induced melanogenesis in B16F10 cells. For anti-wrinkle effect, elastase inhibition activity of the ethanol extract was 53.2% at a concentration of $100{\mu}g/ml$. The antimicrobial activity of the extract against S. aureus and E. coli was observed to be 0.5 - 5%, and no significant activity was noted against C. albicans. Therefore, the ethanol extract of Rosa multiflora can be used effectively for development of functional cosmetic materials.

This study was conducted to investigate the effects of water extract from Rosa multiflora and Rosa multiflora complex on lipid metabolism in rats fed a high cholesterol diet. Experimental rats were divided into four groups, which were composed of normal diet group (N group), high cholesterol diet group (HF group), high cholesterol and 5% Rosa multiflora diet group (HR group), and high cholesterol and Rosa multiflora complex diet group (HRC group). Rosa multiflora complex is composed of Duchesnea chrysantha, Salvia plebeia R. BR., and Sasa borealis. The serum triglyceride (TG) content of the HF group was significantly higher than that of the N group, whereas that of the HRC group was significantly lower. Serum high-density lipoprotein-cholesterol contents of the HR and HRC groups were significantly higher than that of the HF group. The serum total cholesterol and low-density lipoprotein- cholesterol contents of the HF group were significantly higher than those of the N group, and especially the atherogenic index of the HRC group was significantly reduced compared to the HF group. The liver TG and total cholesterol contents of the HF group were significantly increased compared to the normal diet group, while those of the HR and HRC groups were significantly decreased compared to the HF group. Fecal total lipid and total cholesterol contents of the HR and HRC groups were significantly increased compared to the HF group. Uridine 5'-diphospho (UDP)-glucuronyl transferase activity of the HR and HRC groups were increased compared to the HF group. Total bile acid contents of the HR and HRC groups were increased compared to the HF group, and that of the HRC group was significantly increased compared to the HF groups. These results suggest that Rosa multiflora supplementation has powerful health benefits due to UDP-glucuronyl transferase activity, bile acid, and lipid metabolism.

Background: The Rosa multiflora, a well-known plant belonging to Rosacea, is widely used in orthodox medicine in worldwide. However, its biological activity and cosmetic preservative efficacy have not yet been studied. Thus, this species is yet to be defined as a functional cosmetic material. Accordingly, an investigation of the above mentioned atrributes was performed on a 50% ethanol extract of Rosa multiflora. Methods and Results: The antioxidant activity was assessed through free radical scavenging assays with 2,2-diphenyl-1-picrylhydrazyl (DPPH). Additionally, the contents of total phenols and flavonoids were analyzed. The phenolic compounds were detected using HPLC. The antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans was assessed using the disc diffusion assay. The preservative effect (challenge test) on a formulation of soothing gel was performed for 28days. The DPPH radical scavenging ability, denoted by the $SC_{50}$ (half maximal inhibitory concentration for DPPH radical scavenging) value was found to be $131.63{\mu}g/m{\ell}$. The content of total polyphenol and flavonoid content were 202 mg/g and 86.77 mg/g, respectively. In additon, astragalin and gallic acid were identified in the extract. The antimicrobial activity of the extract against S. aureus and E. coli was observed to be 5 - 0.5%, and no significant activity was noted against C. albicans. The ethanol extracts (5% and 10%) met the preservation standards of the Cosmetics, Toiletry, and Fragrance Association (CTFA). Conclusions: Thus the ethanol extract of R. multiflora can be used in cosmetics as a natural preservative and antioxidant.
