본 연구는 절화 국화 ‘백마’의 수확 후 몇가지 포 장재 처리가 선도유지 및 품질에 미치는 영향을 알아 보기 위하여 수행되었다. 개화단계의 결과, PE필름 처 리구에서 대조구에 비해 6일째 개화가 25% 지연되는 결과를 나타내었다. 꽃크기 변화의 경우 기능성 한지 포장재 처리구에서 대조구에 비해 실험 6일째 꽃의 직 경 변화 속도가 19% 지연되는 결과를 나타내었다. 화 색변화의 경우 기능성 한지 포장재(I, II, III) 처리구 모두 대조구에 비해 2일 정도 화색변화가 지연되는 결과를 나타내었다. 생체중 변화의 경우 신문지, PE 필 름, 기능성 한지 포장재(I, II, III) 모두 대조구에 비 해서 높은 수분흡수량을 나타내었다. 특히, 포장재 II 는 절화 국화 ‘백마’의 선도유지에 관련된 품질요인인 개화단계, 꽃크기, 화색변화, 생체중, 에틸렌 발생량에 긍정적으로 작용함을 알 수 있다.

Conjugate trienoic acids (CTA) occurred in triacylglycerols (TGs) of the seed oils of Trichosanthes kirilowii, Momordica charantia and Aleurites fordii, and they were easily converted to their methyl esters in a mixture of sodium methoxide-methanol without any structural destruction. The main fatty acids in triacylglycerol (TG) fraction of the seed oils of Trichosanthes kirilowii are C18:2Ω6 (32.2 mol %), C18:3 9c.11t,13c (38.0 mol %) and C18:1Ω9 (11.8 mol %), followed with C16:0 (4.8 mol %) and C18:0 (3.1 mol %). The TG fraction was resolved into 20 TG molecular species according to the partition number (PN) by reversed-phase (RP)-HPLC. The main TG species were DTc2, MDTc and D2Tc, of which amounts reached 63 mol % of total TG molecular species. The TG sample was fractionated into 11 fractions according to the number of double bond in the molecule by Ag+-HPLC and the species of DTc2, MDTc and D2Tc were also eluted as main components. The TG species containing CTA showed unusual behaviours in the order of elution by HPLC ; first, TG moleular species of DTc2 (D; dienoic acid, Tc; punicic acid, Tci; α-eleostearic acid, M ; monoenoic acid, St; stearic acid) was eluted earlier than Mtc2, although they have the same PN number of 40, and, secondly, the species of DTci2 with eight double bonds was eluted earlier than that of D2Tci with seven double bonds. Intact TG of the seed oils of Momordica charantia contained mainly fatty acids such as C18:3Ω9c,11t,13t (57.7 mol %), C18:1Ω9 (17.4 mol %), C18:0 (12.3 mol %) and C18:2Ω6 (10.6 mol %), and was classified into 13 fractions by RP-HPLC. The main TG species were as follows ; MTci2 [(C18:1Ω9)(C18:3 9c,11t,13t)2, 39.1 mol %] and StTci2 [(C18:0)(C18:3 9c,11t,13t)2, 33.9 mol %] comprising about 73 mol % of total TG species, accompanied by DTci2 [(C18:2Ω6)(C18:3 9c,11t,13t)2, 7.3 mol %], D2Tci [ (C18:2Ω6)2(C18:3 9c,11t,13t), 3.6 mol %] and MDTci [(C18:1Ω9)(C18:2Ω6)(C18:3 9c,11t,13t), 3.5 mol %]. Simple TG species of Tci3 [(C18:3 9c,11t,13t)3] was present in a small amount of 1.4 mol %, but other simple TG species were not detected. The TG was also resolved into 11 fractions according to the number of double bond by Ag+-HPLC, and the species were mainly occupied by MTci2 [(C18:1Ω9)(C18:3 9c,11t,13t)2, 39.4 mol %] and StT-ci2 [(C18:0)(C18:3 9c,11t,13t)2, 35.4 mol %] DTci2 species with eight double bonds was also developed faster than D2Tci one with seven double bonds as indicated in the analysis of TG of the seed oils of T. kirilowii, and MTci2 species with cis, trans, trans-configurated double bond was eluted earlier than MTc2 species with cis, trans, cis-configurated double bond. The main components of fatty acid in total TG fraction isolated from the seed oils of of Aleurites fordii were in the following order ; C18:3 9c,11t,13t (81.2 mol %)〉 C18:2Ω6 (8.5 mol %)〉 C18:1Ω9 (5.4 mol %). With resolution of the TG by RP-HPLC, eight fractions such as Tci3, Dtci2, D2Tci, MTci2, PTci2 (P; palmi..

The lipids from the seeds of Pinus koraiensis mostly composed of triacylglycerols (TGs), in which linoleic acid (46.2 mol%) and oleic acid (25.6 mol%) are present as main components in the fatty acid composition. Surprisingly, they also have unusual fatty acids with δ5-double bond systems such as δ5.9.12-C18:3 (16.0 mol%), δ5.9-C18:2 (2.3 mol%) and δ5.11.14-C20:3 (0.8 mol%). Saturated fatty acids of palmitic, stearic and arachidic acid were present in less than 8.0 mol%. TG was resolved into 17 fractions by reverse-phase HPLC according to so-called partition number (PN) suggested by Plattner, in which TG molecules with δ5-NMDB acyl chains eluted later than did those with δ9-MDB acyl radicals. Ag+-HPLC separated the TG into 14 fractions more clearly than did those with δ9-MDB acyl radicals. Ag+-HPLC separated the TG into 14 fractions more clearly than did reverse-phase HPLC, and the complexity of δ5.9.12-C18:3 moiety with silver ion impregnated in the column bed was in the level between δ9.12.15-C18:3 (C18:3Ω3) and C18:2Ω6 (δ9.12-C18:2). In the Ag+-HPLC, it was found that the molecular species having a given-numbered double bonds widely spreaded in the acyl chains eluted earlier than those concentrated in one acyl chain. The main molecular species are (C18:2Ω6)2/δ5.9.12-C18:3 (14.8 mol%), C18:1Ω9/C18:2Ω6)2 (12.8 mol%) and C18:1Ω9/C18:2Ω6/δ5.9.12-C18:3 (10.9 mol%).

세 개의 탈수한 Ag+이온과 Ca2+ 이온으로 치환한 제올라이트 A(Ag4Ca4-A, AgCa3-A, Ag8Ca2-A)를 0.1 Torr의 Rb 증기로 처리한 결정구조를 공간군 Pm3m을 써서 단결정 X-선 회절법으로 결정하였다. (단위세포상수 a는 각각 12.271(1)a, 12.255(1)a 및 12.339(1)a이다). 이들 구조의 최종 오차인수 R(무게)는 I>3σ(I)가 되는 130 회절반사로 0.072, 110 회절반사로 0.050 및 86 회절반사로 0.082이었다. 각각의 구조에서 Rb 종은 세개의 다른 결정학적 위치에 위치하고 있다. 즉 단위세포당 3개의 Rb+이온은 8-링 중심에 위치하고 약 2.5개 내지 3.0개의 Rb+이온은 소다라이트 동공내 3회 회전축상에 위치한다. 또 Ag 종이 두 개의 다른 결정학적 위치에 위치하고 약 0.7∼2.1개의 Ag+이온은 4-링과 마주보는 위치에, 약 2.2∼4.8개의 Ag 원자는 큰 동공 중심 가까이에 위치한다. 이들 구조에서 단위 세포당 Ag 원자이 수는 각각 2.2, 2.4 및 4.8개이었고 이들은 큰 동공 중심에 헥사실버 클라스터를 만든다. Rb+이온은 8-링을 막고 있어서 Ag가 골조 밖으로 이동하는 것을 막고 있고 각각의 헥사실버 클라스터는 13개의 Rb+ 이온과 배위하여 안정화된다. 단위 세포당 약 0.8개의 Rb원자가 과잉으로 존재하여 삼각 대칭형의 (Rb3)2+클라스터가 소다라이트 동공내의 존재한다. 적어도 하나의 큰 동공의 6-링 Rb+ 이온은 소다라이트 동공의 (Rb3)2+클라스터에 접근하므로 이들 클라스터는 (Rb)43+, (Rb)54+ 혹은 (Rb)65+가 형성될 수도 있다.
