This study investigated the anti-inflammatory effects of Xanthoceras sorbifolia of seeds oil on RAW264.7 macrophages and TPA (12-O-tetra decanoylphorbol-acetate)-induced ear edema mice. MTT assay method to measure cytotoxicity was formed in RAW264.7 cell. The anti-inflammatory effect was measured by ability to inhibit production nitric oxide (NO) in RAW264.7 cell. Hexane and eight-percent methanol fractions from Xanthoceras sorbifolia seeds oil did not show cytotoxicity. Hexane and eight-percent methanol fractions were showed significantly inhibitory effect on NO production. TPA-induced acute edema was developed in the mouse ears, and Xanthoceras sorbifolia seeds oil dissolved in acetone was applied to inflamed ears. It was found out that Xanthoceras sorbifolia seeds oil could significantly reduce th ear swelling, compared to the control. Overall results indicate that the Xanthoceras sorbifolia seeds oil has anti-inflammatory activity and could be used as a resource of anti-inflammatory materials.

본 연구는 문관나무 종자유로부터 새로운 유지자원으로의 활용 가능성을 평가하기 위하여 여러 가지 이화학적 특성분석을 하였다. 문관나무 종자유를 초임계 추출(420 atm, $50^{\circ}C$), 헥산 추출, 가열압착($160^{\circ}C$, $180^{\circ}C$) 방법으로 추출하였다. 그 결과 추출 수율은 헥산 추출이 $53.5{\pm}2.5%$로 가장 높았으며, 다음으로 $160^{\circ}C$ 가열압착 추출이 $48.3{\pm}6.5%$, $180^{\circ}C$ 가열압착 추출과 초임계 추출은 각각 $44.7{\pm}1.7%$, $44.7{\pm}2.5%$의 수율을 보였다. 산가를 측정한 결과, 초임계 추출 종자유가 3.44 mg/g으로 가장 높았으며 가열압착 추출 종자유가 1.3 mg/g 정도로 가장 낮았다. 문관과 종자유의 과산화물가를 측정한 결과, 가열압착 추출 종자유($160^{\circ}C$)가 3.10 meq/kg으로 가장 높았으며 다음으로 가열압착 추출 종자유($180^{\circ}C$)가 2.36 meq/kg, 헥산 추출 종자유와 초임계 추출종자유가 각각 1.59, 1.13 meq/kg 순으로 나타났다. 문관나무의 종자유로부터 지방산 조성을 분석한 결과 oleic acid(C18:1)와 linoleic acid(C18:2)가 60% 이상 함유되어 있었다. 또한 문관나무 종자유의 총 phytosterol 실험 결과 가열압착 추출 종자유($160^{\circ}C$)의 함량이 $65.91{\pm}0.62$ mg/100 g으로 가장 높았다. 본 연구는 문관나무 종자유의 추출방법별 이화학적 특성 분석을 통해 문관나무 종자유 활용에 대한 기초자료로 활용될 수 있을 것으로 판단된다.

Xanthoceras sorbifolia Bunge, the sole species in the genus Xanthoceras, is a flowering plant in the family Sapindaceae. It is an important tree species being a source of edible oil and biodiesel with a capacity as a pioneer of degraded and desert land. Seeds of X. sorbifolia were collected from two plantations and two superior trees in Inner Mongolia; and one plantation and one superior tree in Liaoning, China. An inter simple sequence repeat (ISSR) analysis showed genetic variation among four artificial populations in China: two in Inner Mongolia (IM), one in Liaoning (LN), and one in Shandong (SD). The average percentage of polymorphic loci was 81.25 % for these four populations. Based on an analysis of molecular variance, 23 % of the total genetic variation was found among populations, and 77 % within populations. Traits of seeds varied considerably between and among areas, for example two trees produced quite different seeds in several traits although they are adjacent to each other in the same farm. As much attention has not been paid to the traits of seeds, there should be a genetic test to understand this variation. It is necessary to obtain information on seed characteristics first and then provide basic information for further research on the selection of superior trees and provenances.

Seeds of Xanthoceras sorbifolia Bunge were collected from two plantations and two superior trees in Inner Mongolia: and one plantation and one superior tree in Liaoning, China in late August, 2011. Yellowhorn or goldenhorn is an important tree species, from the aspects of source of edible oil and biodiesel and pioneering capacity of degraded and desert land. Characteristics investigated were seed length, width, and weight: weight and volume of 1,000 seeds: and weight and volume of one-liter seeds. The seeds of Qingsonglingxiang No. 1, growing alone in an open space, showed the highest values in seed length (16.08 mm), width (14.48 mm) and weight (1.40 g), while those of Tree No. 160 in Ar Khorqin Banner were the lowest ones: that is, 11.48mm for length, 11.81 mm for width, and 0.73 g for weight, respectively. Traits of seeds varied quite much between trees and among areas; for example, Tree No. 38 and No. 160 produced quite different seeds in several traits, although they are adjacent to each other in the same farm. Weight of 1,000 seeds varied from 718.0 g to 1,010.1 g and volume from 0.76 L to 1.52 L. Weight of one-liter seeds were 522.3 g to 688.2 g, while the number of seeds were 603 to 935. Seeds which were soaked in the water at $4^{\circ}C$ for 2 days showed the highest germination rate (89%) in a 30-day test, which was about 10% to 40% higher than those of non-treatment and dipping treatment at $36^{\circ}C$ followed by keeping under room temperature for 2 days. 81% of seeds in the wet sand at room temperature germinated, while 23% of seeds deprived of seed coat germinated. It is necessary to understand seed traits to select superior clones or provenances for the increased, unfluctuating production of seed.

Xanthoceras sorbifolia seed coat (XSSC) is a processing residue of the bioenergy crop. This work aimed to evaluate the applicability of using the steam explosion to modify the residue for dye biosorption from aqueous solutions by using methylene blue as a model cationic dye. Equilibrium, kinetic and thermodynamic parameters for the biosorption of methylene blue on the steam-exploded XSSC (SE-XSSC) were evaluated. The kinetic data followed the pseudo-second-order model, and the rate-limiting step was the chemical adsorption. Intraparticle diffusion was one of the rate-controlling factors. The equilibrium data agreed well with the Langmuir isotherm, and the biosorption was favorable. The steam-explosion pretreatment strongly affected the biosorption in some respects. It reduced the adsorption rate constant and the initial sorption rate of the pseudo-second-order model. It enhanced the adsorption capacity of methylene blue at higher temperatures while reduced the capacity at lower ones. It changed the biosorption from an exothermic process driven by both the enthalpy and the entropy to an endothermic one driven by entropy only. It increased the surface area and decreased the pH point of zero charge of the biomass. Compared with the native XSSC, SE-XSSC is preferable to MB biosorption from warmer dye effluents.
