The whole berry, pulp, and seed of sea buckthorn fruit were extracted with supercritical $CO_2$ to produce edible oils. The effects of extraction pressure, temperature, and $CO_2$ flow rate on the oil yield and extraction rate were investigated, and the fatty acid composition, tocopherol, and carotenoid contents of the oils were compared. The results showed that the extraction rate was affected by pressure, temperature, and $CO_2$ flow rate and, in general, the yield increased with a rise in any of the 3 variables. Fatty acids in the whole berry and pulp oil were dominated by monounsaturated fatty acids (>64%), followed by saturated fatty acids (about 30%). In contrast, fatty acids in the seed oil consisted mainly of polyunsaturated (>60%) and monounsaturated fatty acids (>24%). The seed oil had a slightly higher content of tocopherols, but a much lower content of carotenoids, compared with the whole berry or pulp oil.

Background: Ginseng has been used as a traditional medicine and functional cosmetic ingredients for many years. Recent studies have focused on the potential biological effects of the ginseng berry and its ingredients. (+)-Syringaresinol (SYR) is enriched in ginseng berry and its beneficial effects on the skin have been recently reported. However, little is known about the its effects on the wound healing process of skin. Methods: Here, we evaluated the skin wound healing effect of (+)-SYR using the human fibroblast Hs68 cell and ex vivo pig and human skin tissue model. Scratch wound test and hydrogen peroxide (HPO) induce chemical wound model were employed. Results: (+)-SYR promoted the migration and proliferation of Hs68 cells without significant cytotoxicity at the tested concentrations. Especially, in ex vivo pig and human skin tissue, HPO-induced chemical wound was recovered almost completely by (+)-SYR. In line with the finding in Hs68, the protein expression levels of TGF-β and PCNA, a proliferation marker were increased, demonstrating the beneficial effects of (+)-SYR on skin wound repair. Conclusion: Collectively, we demonstrated that (+)-SYR from ginseng berry, can enhance the wound healing effect by accelerating cell proliferation and skin regeneration, suggesting the potential utility of (+)-SYR for skin wound repair.

개량머루의 과립 크기와 생산량을 증가시키기 위한 $GA_3$와 TDZ 처리의 효과와 적정 처리 농도를 구명하기 위하여 본 실험을 수행하였다. $GA_3$ 처리는 모든 처리구에서 모두 과립 비대 효과를 보였으며 100과 $200mg{\cdot}L^{-1}$ 처리구의 과립이 가장 컸다. 또한 $GA_3$ 처리구는 착립수가 증가하여 과방중이 크게 생산되었으나 당도 및 산도에 전혀 차이가 없었다. $200mg{\cdot}L^{-1}$ 처리구에서 과피 오염 및 탈립과 같은 약해가 발생되었다. $GA_3$와 TDZ 혼용 처리에서는 $GA_3$ 혹은 TDZ의 농도가 높은 처리구의 과립이 크기는 크지만 과실의 성숙이 지연되어 당도가 낮고 산도가 높은 과실이 수확되었다. $GA_3$와 TDZ를 처리했을 때 과피 조직은 세포층수에는 변화 없이 유관속 조직까지의 길이가 증가하였다. 따라서 개량머루의 $GA_3$ 와 TDZ처리는 세포 분열에는 영향 없이 세포 크기가 증가됨으로 인해 과립 크기가 증가하였다. 개량머루는 착립이 결정되는 시기가 짧기 때문에 착립 직후 2~3회에 나누어 처리해야 착립률을 향상시킬 수 있었다. 개량머루의 과립 비대와 착립률을 향상시키기 위해서는 $GA_3$ $100mg{\cdot}L^{-1}$ 이하의 단독 처리 혹은 $GA_3$ 50+TDZ $1.25mg{\cdot}L^{-1}$의 혼용 처리가 적합할 것으로 판단되었고 TDZ 처리에 의해 과실의 성숙이 지연되므로 성숙과를 수확하도록 주의해야 할 것으로 생각된다.

변색기의 수준별 야간 고온이 포도 '거봉'의 과피색 발현에 미치는 영향을 분석하기 위해 시기별 과피색 변화, 과피 내 안토시아닌 및 식물호르몬 ABA와 GA 함량을 분석하였다. 변색기 20일 동안의 야간 24, 27℃ 처리에 의해 '거봉' 포도의 과피색 불량이 나타났으며, 야간 온도가 높을수록 과피색 발현이 더욱 억제되었다. 수확기 과실 품질을 분석한 결과, 야간 21℃ 처리구에 비해 24, 27℃ 처리구의 과방중, 과립중, 당도가 감소하였다. 야간 21℃ 처리구의 과피에서 만개 후 50일부터 안토시아닌이 축적되기 시작했고, 개별 안토시아닌 중 Mal과 함께 총 안토시아닌 함량이 수확기까지 지속적으로 증가하였다. 야간 21℃ 처리구를 기준으로 과피의 총 안토시아닌이 야간 24, 27℃ 처리에 의해 감소하였으며, 개별 안토시아닌 중에서는 Peo를 제외한 나머지 안토시아닌의 감소 경향이 뚜렷하였다. 식물호르몬 ABA는 야간 21℃ 처리구의 과피에서 변색기에 최대값을 보이고 다시 수확기까지 감소하였는데, 이러한 ABA 함량의 증가는 야간 24, 27℃ 처리에 의해 감소하는 경향이었다. GA는 변색기 과피에서 급격하게 감소하여 수확기까지 낮은 함량으로 유지되었는데, 야간 기온이 낮을수록 빠르게 감소하였다. 야간 21℃ 처리구 과피에서 ABA/GA 값은 만개 후 60일에 최대값을 보이고 다시 수확기까지 감소하였지만, 이 증가 양상이 야간 고온에 의해 감소하며 과피 안토시아닌 축적과 동일한 경향을 보이며 변화하였다. 따라서 변색기 야간의 24℃ 이상의 고온은 '거봉' 포도의 과피색 발현을 억제하며, 이는 식물호르몬 ABA, GA의 비율 변화, 과실 당도 감소로 인한 총 안토시아닌 함량 및 조성 변화 때문으로 판단되었다.

Consider the nonparametric regression model $Y_{ni}\;=\;g(x_{ni})+{\epsilon}_{ni}$ ($1\;{\leq}\;i\;{\leq}\;n$), where g($\cdot$) is an unknown regression function, $x_{ni}$ are known fixed design points, and the correlated errors {${\epsilon}_{ni}$, $1\;{\leq}\;i\;{\leq}\;n$} have the same distribution as {$V_i$, $1\;{\leq}\;i\;{\leq}\;n$}, here $V_t\;=\;{\sum}^{\infty}_{j=-{\infty}}\;{\psi}_je_{t-j}$ with ${\sum}^{\infty}_{j=-{\infty}}\;|{\psi}_j|$ < $\infty$ and {$e_t$} are negatively associated random variables. Under appropriate conditions, we derive a Berry-Esseen type bound for the estimator of g($\cdot$). As corollary, by choice of the weights, the Berry-Esseen type bound can attain O($n^{-1/4}({\log}\;n)^{3/4}$).

This study was conducted to investigate the physiological activity of acai berry (Euterpe oleracea Mart.) extracts from three different solvents (water, methanol, and ethanol). We measured total polyphenol and total flavonoid content, DPPH radical scavenging activity, nitrite scavenging activity, metal chelating effect, and reducing power. The extraction yield from water, methanol, and ethanol was 17.10, 9.50, and 37.51%, respectively. The highest total polyphenol content (10.54 mg/100 g) and total flavonoid contents (1.88 mg/100 g) was observed in water extract. DPPH radical scavenging activity was the highest in both water extract (72.03%) and methanol extract (74.79%) at levels of 5 mg/mL, which was similar to that of BHT (78.90%). Water extract yielded the highest metal chelating effect (92.54%) and reducing power (1.09) at levels of 5 mg/mL. Taken together, these findings suggest that extracts of acai berry can be used as functional food materials with antioxidative and nitrite scavenging activities.

Background: This study was carried out to determine the best time for collecting ginseng berries without reducing the ginsenoside-Re content of ginseng roots, which are used as food, medicine, or cosmetic materials. Methods and Results: The test variety of ginseng used in this study was is Chunpung, which was collected from a 4-year-old ginseng field. Ginseng berries were collected at 7, 14, 21, 28, 35, 42, 49, and 56 days after flowering. The number of berry bunches per $1.62m^2$ ranged from 43.4 to 61.4, while the weight of berries per $1.62m^2$ was the greatest when they were collected 49 days after flowering. The root fresh weight per $1.62m^2$ was increased by 0.21 - 1.00 kg compared with that before the test, but root weight gain was decreased as the berry collection time was delayed. Total ginsenoside content of 4-year-old ginseng was the highest when berries were collected 7 days after flowering, while the ginsenoside-Re contents was the highest when collection was done 14 days after flowering. Conclusions: The most suitable period for ginseng berry collection was proposed to be from 14 to 21 days after flowering, as this is when the content of ginsenoside-Re, which is useful as a medicinal or cosmetic material, is still high and the ginseng root has not yet decreased in weight.

The purpose of this study is to develop a new preparation process of ginseng berry extracts having high concentrations of ginsenoside Rh1, Rg2, Rg5, F4, a special component of red and black ginseng. Chemical transformation from ginseng saponin glycosides to prosapogenin was analyzed by the HPLC. Extracts of ginseng (Panax ginseng) berry was processed under several treatment conditions including ultrasonication treatments. The content of total saponin reached their heights at 6 hr (UGB-6, 61.760%) of ultrasonication treatment, followed by 10 hr (UGB-10, 53.009%) and 9 hr (UGB-9, 50.652%) of ultrasonication treatment at $100^{\circ}C$. Results of those treatments showed that the quantity of ginsenoside Rh1 increased by over 15% at 10 hr of ultrasonication treatment at $100^{\circ}C$. The results of processing with UGB-10 indicate that the ultrasonication processed ginseng berry extracts that had gone through 10 hr treatments were found to contain the largest amount of ginsenoside Rh1 (15.358%), Rg2 (6.301%), Re (4.567%) and F4 (2.658%). In addition, UGB-6 contained ginsenoside Rg3 (13.632%) at high concentrations. It is thought that such results provide basic information in preparing ginseng berry extracts with functionality enhanced.
