The volatile components, normal hydrocarbons, organic acids, and nonvolatile fatty acids in the various parts of Luffa cylindrica(L.) Roemer(sponge-gourd) were analyzed by GC and GC/MS. More than 150 volatile components were separated and thirty seven components were identified and quantified. The contents of essential oil were 0.05%, 0.05%, and 0.08% on a dried weight base in leaves, stem, and seeds respectively. Fruit juice and sap contained 0.06% and 0.03% oil on the fresh weight base. Twenty six components of normal hydrocarbons in leaves, stem, seed, and unripe fruit were separated, identified, and quantified. The total concentrations of the hydrocarbons were $75.5\;{\mu}g/g$ in leaf, $52.0\;{\mu}g/g$ in stem, $46.6\;{\mu}g/g$ in fruit juice, and $32.8\;{\mu}g/g$ in seed fractions. The major hydrocarbons in leaves, stem, and fruit juice were $nC_{25}$, $nC_{27}$, $nC_{29}$, and $nC_{31}$, $nC_{16}$, $nC_{17}$, $nC_{18}$, and $nC_{19}$ were abundant in seeds mainly. The concentration of malonic acid among the five organic acids was highest in leaves, stem, and flowers. Unripe fruit contained 24.5 mg/g of the five organic acids and malic and citric acids were higher. The concentrations of palmitic, linoleic, and linolenic acids were higher concentration in the various parts of sponge-gourd and palmitic acid was distributed in the most parts. The concentrations of organic and fatty acids in the sap were negligible.

In this study, Rubus idaeus (Raspberry) cultivar 'Willamette' fruit extract(RIFE) was prepared from the freeze-dried raspberry powder, n-hexane and ethyl acetate, and then the phenolic compound content, ferric reducing ability, and radical scavenging ability were measured. The raspberry cultivar 'willamette', 'polka', and 'polana' compound fruit extract did not show cytotoxicity up to the concentration of 10%. As a result of conducting an experiment at the concentration, it was confirmed that the total phenolic compound content was 375.3 ppm, and the total flavonoid content was 43.46 ppm, and the ferric reducing ability by ferric reducing antioxidant power (FRAP) reagent was equivalent to FeSO4 0.532 mM. It was confirmed that 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging ability was 94.5 ± 0.7%, and the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging ability was 99.4 ± 2.82%, and the nitric oxide (NO) radical scavenging activity was 88.5 ± 0.4%. When compared with the L-ascorbic acid 'standard' solution, DPPH radical scavenging ability was between 25 - 50 ppm / ABTS radical scavenging ability was close to 100 ppm / NO radical scavenging ability was more than 1,000 ppm. These results suggest that the raspberry cultivar 'willamette' fruit extract could be applied as an effective cosmetic material with antioxidant activity.

The effective components of Schisandra chinensis are lignans (schizandrins and gomisins), which have various physiological functionalities such as anti-cancer, anti-inflammatory, and antioxidant activities. This study was carried out to determine the different parts of fruits in Schisandra chinensis to elevate their usefulness. Schisandra chinensis was separated into skin (epicarp), pulp (mesocarp), and seeds, and raw Omija and hot-dried Omija (HDO) were used as control. The most abundant component was nitrogen free extract (6.88~56.70%) followed by crude lipids (1.65~19.04%). The main mineral was K (383.10~2,024.10 mg/100 g), except in seeds where P was the main mineral. The main lignan in all parts of fruit was schizandrin, and the highest content of schizandrin was 9.46 mg/g in dried seeds. Total lignan content was 25.97 mg/g and 14.97 mg/g in dried seeds and HDO, respectively. A total of 17 components of fatty acids in seeds and HDO were detected, of which linoleic acid (72.66~73.78%), oleic acid (14.78~17.39%), palmitic acid (2.88~3.54%), and capric acid (1.70~4.93%) were determined as the major components. Main lignans and fatty acids of Schisandra chinensis fruit contain mainly seeds. Therefore, it is more efficient to use seeds than pulp and extract of fruit itself to use the components of Omija.

The physiological functionalities of 70% ethanol extracts (EE) from Cudrania tricuspidata fruit (ECFD, EE of C. tricuspidata subjected to freeze-drying; ECHD, EE of C. tricuspidata subjected to heat air drying; ECID, EE of C. tricuspidata subjected to infrared drying) were investigated. Yields of freeze-dried powders of ECFD, ECHD, and ECID were 51.50%, 53.91%, and 56.14%, respectively. Color $L^*$, $a^*$, $b^*$, and $H^{\circ}$ values of ECHD and ECID decreased. Dried ECHD and ECID had relatively higher contents of total polyphenolics and flavonoids than ECFD. Electron donating abilities at a concentration of 10 mg/mL (w/v) were in order of ECID (62.37%) >ECHD (80.17%)>ECFD (77.80%). Reducing powers ($OD_{700}$) of ECFD, ECHD, and ECID were 0.75, 1.70, and 1.89, respectively. Additionally, ABTS radical scavenging ability of ECID was the highest with a value of 62.37% at a concentration of 10 mg/mL (w/v). Nitrite scavenging activities of ECFD, ECHD, and ECID at a concentration of 10 mg/mL (w/v) were 28.76%, 30.69%, and 41.64%, respectively. SOD (superoxide dismutase)-like activities at 5 mg/mL (w/v) were in the order ECFD (891.93 mUnits)>ECHD (723.02 mUnits)>EFID (611.97 mUnits). Whereas ferrous ion chelating activity of ECFD (52.36%) and ECID (47.16%) was significantly higher than that of ECHD (30.04%). ACE inhibitory and xanthine oxidase (XO) inhibitory activities of ECHD and ECID at a concentration of 1 mg/mL (w/v) were higher than those of ECFD. In conclusion, we provided experimental evidence that extracts of pre-dried C. tricuspidata exhibit increased physiological functionalities. Further, infrared drying technique is the best method for enhancement of antioxidant activity of C. tricuspidata fruit.

This study was performed to determine the effects of pretreatment (NT: non-treatment, BTS: boiling treatment with 3% sodium chloride, DTG: dipping treatment in glycerol) and drying methods (sun drying, hot air drying, and cold air drying) on the physicochemical properties and antioxidant activities of dried jujube (Zizyphus jujuba Mill.) fruits. Our results show that moisture content is lower (P<0.05) with DTG, and that moisture content is lower with hot air drying compared to other drying methods. The bulk density was highest with BTS. The soluble solids content was highest with DTG. Additionally, the soluble solids content were highest in the following order: hot air drying> cold air drying> sun drying. The titratable acidity of hot air drying was highest of all the drying methods. The titratable acidity was higher with NT and DTG, and the brix and acid ratio of sun drying was higher than other drying methods. Among the drying methods, BTS showed the best browning-retarding effect, whereas boiling treatment affected quality and color. The total polyphenol content from hot air drying and NT or DTG treatment was relatively higher than the content from BTS. The flavonoid content was highest with BTS, and all dried jujube showed relatively high antioxidant activities. The sensory evaluation results indicated that the organoleptic scores for overall preference were higher in the NT and DTG treatment groups. These results suggest that pretreatment and drying methods affect the quality of dried jujube fruit, and show that glycerol treatment with hot air drying can be applied to the production of high quality dried jujube.

The purpose of this study was to perform a functional components analysis and investigate the physical properties of powders made from the stems or fruit of freeze-dried Cheonnyuncho cactus (Opuntia humifusa). The functional components analysis showed that the stem and fruit powders han vitamin C levels of 42.14 mg and 105.21 mg, respectively. The stems powder contained more lutein than the fruit powder. The fruit powder contained more vitamin C than the stem powder. The SDF (soluble dietary fiber) and IDF (insoluble dietary fiber) in the stem powder were 45.24% and 22.15%, respectively, which were higher then the values for the fruit powder. The stem and fruit powders contained 19.30 mg/g and 25.10 mg/g of crude saponin, respectively. The pH of the stem and fruit powders was 5.34 and 5.07, respectively, both indicating low acidity. The L, a and b values of the stem powder color were 78.28, -3.71, and 19.19, respectively. The L, a and b values of the fruit powder color were 55.56, 24.84, and -3.18, respectively. The stems powder had a higher bulk density, water holding capacity, and swelling power than those of the fruit powder, but water-retaining capacity of the stem powder was lower than that of the fruit powder. In addition, the stems powder had a higher viscous material content and water uptake compared to the fruit powder. Based on the above results, we determined that Cheonnyuncho (Opuntia humifusa) powder had potentially useful functional components and physical properties.

Flavonoids, non-nutrient secondary metabolites of plants, are widely distributed in commonly consumed agro-food resources. Flavonoids include aglycones, and their glycosides are reported to have potential health-promoting compounds. The aim of this study was to investigate flavonoid glycosides in the fruit and leaves of Zizyphus jujuba var. inermis (Bunge) Rehder (jujube). A total of six flavonoids (five flavonols and one chalcone) were identified in jujube fruit and leaves by using ultra-performance liquid chromatography-diode array detector-quadrupole time of flight mass spectrometry along with chemical library and an internal standard. In positive ion mode, six flavonoids were linked to the C- and O-glycosides which were conjugated with sugar moieties based on kaempferol, quercetin, and phloretin aglycones. Total flavonoid contents of leaves (8,356.5 mg/100 g dry weight (DW)) was approximately 900-fold higher than that of fruit (fresh fruit, 13.6 mg/100 g dry DW; sun-dried fruits, 9.2 mg/100 g dry DW). Quercetin 3-O-rutinoside (rutin) and quercetin 3-O-robinobioside were the predominant flavonols in fruit and leaves of jujube. In particular, rutin had the highest content (6,735.2 mg/100 g DW) in leaves, and rutin is a widely reported bioactive compound. Phloretin 3',5'-di-C-glucoside (chalcone type) was detected only in leaves. The leaves of jujube contain a high content of flavonoids and the results of this study indicate that jujube leaves may be a source of bioactive flavonoids.
