“…Tyrosinase activity was determined based on a modification of a previously described method 20 . Total cell counts were determined using a hemocytometer and 2 × 10 4 cells/cm 2 were treated with various concentrations of the test compounds, followed by addition of α-MSH to give a final concentration of 100 nM.…”

“…16 OFE can also reduce the tyrosinase activity and melanin formation of B16F10 cells in a dose-dependent manner. 17 O. fragrans flower contains abundant PeGs, in which acteoside is the main compound. The acteoside in O. fragrans flower, originating from different places, ranges from 36.7 mg/g dry weight (DW) to 72.9 mg/g DW.…”

Osmanthus fragrans flower extract (OFE) is an organic extract from O. fragrans flower, which exhibits neuroprotective, free radical scavenging, and antioxidant effects. Therefore, the protective effect of OFE and acteoside against aging was studied. An aging ICR mouse model was established by chronically administering d-galactose (250 mg/kg) for 8 weeks. d-galactose induced spatial learning and memory impairments that were successfully inhibited by OFE and acteoside, which could shorten escape latency, improve platform crossing times, and increase zone time. The antioxidant potential of OFE and acteoside in vivo was evaluated by estimating the following: activities of antioxidant enzymes, such as glutathione peroxidase and aging-related enzyme, particularly monoamine oxidase; contents of lipid peroxidation methane dicarboxylic aldehyde, advanced glycation end products, and 8-hydroxy-2'-deoxyguanosine (a DNA damage product); and levels of nuclear factor-erythroid 2-related factor 2. OFE and acteoside also inhibited d-galactose-induced neurological aging by suppressing the increase in glial fibrillary acidic protein and neurotrophin-3. Considering the dose-dependent protective effects of OFE and acteoside, we concluded that OFE, rich in acteoside, was a good source of natural antiaging compounds.

“…It is widely distributed in China, Japan, Thailand, and India, and was introduced in Europe late in the 18th century (Zang et al, 2003). Owing to their pleasant scent and biological properties, sweet osmanthus flowers are not only used as natural and functional food flavor additives (Wu et al, 2009), but also have potential medicinal value (Tsai et al, 2007;Lee et al, 2011;Hung et al, 2012). The sensory perception of the aromas in the Albus (former O. fragrans var.…”

Abstract:Objective: Aroma is the core factor in aromatherapy. Sensory evaluation of aromas differed among three sweet osmanthus (Osmanthus fragrans) cultivar groups. The purpose of this study was to investigate the aroma-active compounds responsible for these differences. Methods: Gas chromatography-olfactometry (GC-O) and GC-mass spectrometry (GC-MS) were used to analyze the aroma-active compounds and volatiles of creamy-white ('Houban Yingui', HBYG), yellow ('Liuye Jingui', LYJG), and orange ('Gecheng Dangui', GCDG) cultivars. Results: Seventeen aroma-active compounds were detected among 54 volatiles. trans-β-Ocimene, trans-β-ionone, and linalool, which were major volatiles, were identified as aroma-active, while cis-3-hexenyl butanoate, γ-terpinene, and hexyl butanoate were also aroma-active compounds, although their contents were low. Analysis of the odors was based on the sum of the modified frequency (MF) values of aroma-active compounds in different odor groups. HBYG contained more herb odors, contributed by cis-β-ocimene and trans-β-ocimene, while LYJG had more woody/violet/fruity odors released by trans-β-ionone, α-ionone, and hexyl butanoate. In GCDG, the more floral odors were the result of cis-linalool oxide, trans-linalool oxide, and linalool. Conclusions: Aroma-active compounds were not necessarily only the major volatiles: some volatiles with low content also contributed to aroma. The aroma differences among the three cultivars resulted from variation in the content of different odor groups and in the intensities of aroma-active compounds.
