  • As one of the serial studies on the specific and indigenous plants of Mt. Chiri the constituents of aerial part from filipendula formosa (Rosaceae) were investigated. From of the MeOH extract, five flavonol glycosides, kaempferol-3-O-$\beta$-D-galactopyranoside, querecetin-3-O-$\beta$-D-galactopyranoside, quercetin-3-O-$\alpha$-Lrhamopyranosyl (1 6)-$\beta$-D-galactopyranoside, kaempferol-3-O-$\alpha$-L-rhamnopyranosyl (1 6)-$\beta$-D-galactopyranoside and quercetin-7-O-$\beta$-D-glucopyranosy-3-O-$\beta$-D-galactopyranoside were isolated by column chromatographic separation using Amberlite XAD-2 and Sephadex LH-20, and identified physicochemical evidences (IR, FAB-Mass, $^1H,{\;}^{13}C-NMR$).

  • Two species of Leycesteria, L. gracilis (Kurz) Airy Shaw and L. formosa Wall. (Caprifoliaceae), from the Lao Cai and Yen Bai Provinces are reported here as a new generic record for the flora of Vietnam. During floristic surveys of northern Vietnam, L. gracilis and L. Formosa were encountered. A critical morphological study of all the collected specimens and the type of materials consulting the relevant literature led us to confirm the identity of our collected specimens as L. gracilis and L. formosa. The genus differs from other Vietnamese genera of Caprifoliaceae by the presence of a spike inflorescence or flowers in sessile whorls of 6. Taxonomic notes, description, and photographs are provided, together with short notes on the distribution, ecology and phenology of the two species.

  • The purposes of this study were to determine phenolic compounds and to evaluate antioxidant activities of plums (Soldam, Oishiwase and Formosa). Soldam contains the highest amount of total phenolics among cultivars (Formosa: 4.0%, Oishiwase: 3.3%, Soldam: 6.4% for total phenolic) as well as the total flavonoids of which constituents were mainly myricetin and anthocyanidin. The antioxidant activities were measured by DPPH, ABTS radical scavenging, and SOD-like activities. The DPPH radical scavenging activity of Korean plum extracts (200 ${\mu}g/mL$) showed more than 43%, and the Soldam turned out to be the highest : ID50 value: 160-177 ${\mu}g/mL$ for Formosa and Oishiwase; 58-64 ${\mu}g/mL$ for Soldam. The ABTS radical scavenging activity of Korean plum extracts (200 ${\mu}g/mL$) was found to be more than 50%. The SOD-like activity of Korean plum extracts (200 ${\mu}g/mL$) showed more than 70%. Among three kinds of cultivars, Soldam had the highest antioxidant activity. The nitrite scavenging activity of Soldam was 61.5%, which is the highest, compared with that of the other cultivars, about 50%. From these results, Korean plums turned out to be phytochemical rich fruit as well as to show high antioxidant activities.

  • 'Formosa' plums were picked at three maturity stages according to skin redness, treated with $1{\mu}L{\cdot}L^{-1}$ 1-MCP at $10^{\circ}C$ for 24 h and then stored for 21 days at $10^{\circ}C$. Ethylene production, respiration rate, firmness, color, TSS, TA, and ethanol concentration were determined. Total phenolic content, total flavonoid content, and antioxidant capacity were determined periodically by separating the flesh from the peel. Ethylene production and respiration rate were strongly inhibited in all stages of the 1-MCP-treated fruit, while ethylene production dramatically increased in all stages of non-treated fruit until 11 days after harvest, after which it decreased until the end of the experiment. The respiration rate of the stored fruit increased for 11 days in stages 1 and 2 and for 7 days in stage 3 and decreased after. 1-MCP-treated fruit in all stages showed delay in fruit quality changes such as firmness, TA, skin color, and ethanol concentration, but non-treated fruit did not. Total phenolic contents, total flavonoid contents and antioxidant capacity of 'Formosa' plums were not affected by 1-MCP treatment or maturity stage. However, those values were higher in the peel than in the flesh.

  • The objective of this study is to evaluate the anti-cancer and anti-inflammatory activities of plum (Formosa, Oishiwase, Soldam) for the future development of functional food products. To determine the anti-inflammatory effect of different types of plums, the inhibitory effect of plum extracts on nitric oxide (NO) production were measured in lipopolysaccharide (LPS)-stimulated Raw 264.7 mouse macrophage cells and human cancer cell lines (A549, Ags, Hela, Hep3B). Among the three different plum cultivars, Oishiwase at a concentration of 1 mg/mL showed the highest inhibitory effects on NO production (%) in Raw 264.7 macrophage cells. Moreover, Oishiwase exhibited a higher anti-cancer activity against A549 (renal carcinoma, 50%), Ags (gastric carcinoma, 35%), HeLa (cervical carcinoma, 50%), and Hep3B (hepatocellular carcinoma, 31%) at a concentration on 1 mg/mL, respectively, compared to Formosa and Soldam. Our findings suggest Oishiwase plum extracts may serve as potential dietary sources of natural health promoting substances.

  • 본 연구는 1-MCP가 'Formosa' 자두의 저장 중 품질 변화와 유통기간 연장에 미치는 효과를 밝히고자 수행하였다. 수확한 'Formosa' 자두를 균일한 크기와 색깔로 선별한 후 수확 당일 그리고 수확 후 1일 후에 걸쳐서 각각 1-MCP를 $1{\mu}L{\cdot}L^{-1}$ 농도로 $20^{\circ}C$에서 16시간 동안 처리하여 대조구(무처리)와 비교하였다. 1-MCP를 처리한 후 14일 동안 상온에서 자두의 연화도, 과중감소율, 가용성고형물 함량 변화, 산도, 그리고 과실의 색깔 변화를 측정하였다. 과중감소율과 과실연화도는 1-MCP 처리구가 무처리구에 비해서 적은 변화폭을 보여주었다. 1-MCP 처리 시기(수확당일 그리고 수확 후 1일) 간에는 따른 큰 차이는 없었다. 가용성고형물 함량에는 통계적 유의성은 없었으나, 1-MCP처리구의 과실에서는 산도와 과실의 색깔 변화가 무처리구에 비해서 적게 나타났다. 또한 1-MCP는 저장 중에 발생하는 과실의 부패병 억제효과를 나타내었다. 따라서 본 연구결과, 1-MCP 처리시기(${\geq}1$일) 연장은 상온저장시 과실의 경도, 산도, 과일 색깔 변화에 큰 영향을 미치지 않았으며, 또한 과실품질 유지에 실용성이 있는 결과를 보여주었다.

  • 1) The greater parts of rail road cross tie wood in Korea have been supplied by the imported woods from foreign countries such as Formosa (Taiwan) and Japan. However on account of anatomical properties on these imported woods are not known when newly imported, identification and preservative treatment are apt to fail. Accordingly this expriment was accomplished by the need of application of anatomical properties for the preservative treatment and identification of several imported woods. 2) In this study macroscopical and microscopical properties were inspected and briefly described about four species (Cyclobalanopsis gilva Blume, Castanopsis longicaudata K. et H., Machilus longiflora Hay and Schima superba Gard et Champ) from Formosa and one (Fagus crenata, Blume) from Japan. With several native species these are important as the rail road tie wood in Korea. 3) According to the results measured values of the vessels and fibers of each tested species are as following table.
