Perilla (frutescens) seed oil, which is widely used as a source of vegetable oil in Korea, contains a strikingly large amount (58.4% of total fatty acids) of polyunsaturated linolenic acid (18 : 3) which is one of the essential fatty acids. Our hypothesis was that vitamin E contained in this oil would not be enough to prevent peroxidation of this polyunsaturated oil. A comparative study was carried out using rats and chicks devided into seven groups with various diet combinations emphasizing fat sources for the period of four weeks. The level of fat in each diet was 15% and animals were fed ad libitum. Various diet combinations were as follows; perilla seed oil and sesame seed oil with and without vitamin E supplementation, tallow as a saturated fat source and perilla seed hull group (10% at the expense of carbohydrate). The fat constituents of control group were consisted of 50% vegetable oil and 50% animal fat. A few important findings are as follows: 1. Rats fed perilla seed oil lost their hair focally around the neck and suffered from a bad skin lesion at the same place. In chicks, yellow pigmentation both of feather and of skin was clearly observed only in groups fed perilla seed oil with or without vitamin E supplementation. The basis of biochemical mechanisms of this phenomena remains as an important research interest. 2. The mean value for hematocrit was significantly lower for the chicks fed perilla seed oil than for those fed control diet. This result seems to be attributable to the effect on the red cell membrane known as peroxidation-hemolysis of vitamin E deficiency. 3. The serum cholesterol level was higher for the rats fed perilla seed oil than for those fed control diet, whereas in chicks the group fed perilla seed oil showed lower value than the control group indicating that different animal species could vary in their responses to the same diet. 4. In pathological examinations, the sign of hepatic fibrosis was seen in the perilla seed hull group and it was noticeable that the level of hepatic RNA was significantly increased in the rat recovering from vitamin E deficiency. It is hoped that more detailed studies on perilla seed oil and hulls will soon be carried out in many aspects especially i) at various levels of fat in the diet, ii) in relation to dietary selenium level and iii) to find an optimum level of dietary essential fatty acids in terms of P/S ratio using various animal species. In the mean time, the public should be informed to preserve this particular oil with care to minimize fatty acid oxidation and should be discouraged from overconsuming this oil. This study was supported by UB (United Board) Research Grant (Graduate School, Yonsei University, Seoul, Korea)

This study was performed to investigate the effect of Perilla frutescens Herba extract on the treatment of chromaticity and colorfastness. Perilla frutescens Herba has been used as a Korean medicine. It is effective in removing dangerous for an unborn child and suppressing pain. It is also good as a detoxification and in treating cold. In the long history of Korea, dyeing has been applied for a means representing the grace of natural and inner esthetic consciousness of man. Vegetable dyes give us such great benefits, diversified color, but no pollution. And ramie fabric has distinctive features such as beautiful brilliance, elegance, and strong durability. So, it is regarded as a special product of Korea traditionally. These studies were carried out to treat with acetate iron, dichloride copper and alum with a mordant to ramie fabric. The ramie fabric was died with Perilla frutescens Herba extract. The results of experiment showed as follows: First, the chromophoric degree was the highest in acetate iron but not distinction in another mordants. Second, the light colorfastness was the highest in non treated and dichloride copper, but alum was the lowest. Third, the discoloration was alum and dichloride copper showed first grade in washing colorfastness. Abrasion colorfastness was not significant in this test. According the previous results, Perilla frutescens Herba has an efficiency in removing skin disorders and suppressing pain. So it considered that Perilla frutescens Herba can be applied effectively to theraphy of detoxification and in treating cold.

This study was designed to observe the effects of the mixed diets of edible mushrooms and vegetables oils on the lipid component and fatty acid composition in liver of the diet induced hydpercholesterolemic rats. Ten groups of male S.D. rats were fed a basal diet supplemented with 5% of one of three mushrooms(G.I, L.e, A.j) and 10% of one of three vegetable oils (olive ,safflower perilla) for three weeks. In liver, total cholesterol concentration was significantly low in group 3 (olive oil 10 % + L. edodes 5%) and 6 (safflower oil 10 % $_2$L. edodes 5%) , triglyceride concentration was low in groups 8 (perilla oil 10 % + g. lucidum 5%) and 9 (perilla oil 10% + L. edodes 5%) and phospholipid concentration was significantly low in groups 3, 5, (safflower oil 10 % + G.lucidum 5%), 6, 7 (safflower oil 10 % + A .judae 5%) 8, 9 and 10 (perilla oil 10% + a. judae 5%). in the fatty acid composition of total lipid inliver, monounsaturated fatty acid (MUFA) concentration s were high in groups 2 (olive oil 105 + g. lucidum 5%), 3, and 4 (olive oil 10% + A. judae 5%) and all the perilla oil groups, polyunsaturated fatty acid (PUFA) and linoleic aicd concentrations were signifciantly high in all the safflower oil groups. In the fatty acid composition of liver phospholipid , PUFA concentrations were ghih but MUFA concentrations were low. In the triglyceride component, MUFA were some more than saturated fatty acid (SFA) . In the cholesteryl ester component, MUFa concentrations were significantly high. In the fatty acid composition of liver lipid components, linholeic acid was high in the PUFA and so it was major fatty acid. Eicosapentaenoic acid (EPA) of phospholipid component in liver was significantly high.

Vegetable oils are a rich source of bioactive substances. Phytosterols in those have been known for many years for their properties for reducing blood cholesterol levels, as well as their other beneficial health effects. Phytosterols are triterpenes that are important structural components of plant cell membranes just as cholesterol does in animal cell membranes. The aim of this study was to provide consumers with information about phytosterol contents in vegetable oils in Korea market. The contents of major phytosterols (campesterol, stigmasterol, β-sitosterol) in 50 vegetable oils of 10 kinds (perilla oil, peanut oil, avocado oil, olive oil, pine nut oil, sesame oil, canola oil, coconut oil, grape seed oil, and sunflower oil) were analyzed by gas chromatography with flame ionization detector. The average contents of vegetable oils containing 5 or more samples were in the order of sesame oil (334.43 mg/100 g), perilla oil (262.16 mg/100 g), grape seed oil (183.71 mg/100 g), and olive oil (68.68 mg/100 g). Phytosterol content of sesame oil and perilla oil was high among vegetable oils.

들깻잎 생산 전용품종은 대부분 만생종으로서 우량종자를 채종하고자 할 경우 도복 등이 발생하지 않아 생육관리가 용이하면서 종실 충실도가 높은 파종적기를 설정할 필요가 있다. 이에 중부지역 비닐하우스에서 잎들깨 생산 전용 품종 '잎들깨 1호'를 시험재료로 하여 5월 6일부터 7월 15일 까지 10일 간격으로 8회 파종하여 생육, 도복 발생 여부, 적산온도 및 수량성을 분석하였다. 1. 파종시기가 늦을수록 경장이 짧아지고, 주경절수, 분지수, 화방군수와 화방당 삭수는 감소되었다. 그러나 파종시기가 빠를수록 지상부 생육이 왕성하여 도복이 발생하였다. 2. 개화일수는 파종시기가 늦어질수록 직선적으로 감소되었는데 5월 6일을 기준으로 파종이 1일 지연되면 개화일수는 0.86일씩 단축되었고, 개화기부터 성숙기까지의 결실일수는 29~31일로 파종기 이동에 따른 차이가 없었다. 3. 등숙립율과 종실수량은 5월 6일 파종부터 6월 15일 파종까지 유의성이 없었고, 6월 25일 파종 이후부터 급격히 감소되었다. 4. 등숙에 필요한 적산온도, 도복 발생 여부, 등숙립율과 발아율 등으로 판단하면 만생종 잎들깨 품종의 중부지역 비닐하우스에서 파종적기는 6월 5일(정식 7월 5일)~6월 15일(정식 7월 15일)이었고, 이때 10월 28일~11월 3일경에 성숙되어 종자생산이 가능하였다. 5. 연차에 따라 $0^{\circ}C$ 이하로 떨어지는 시기가 일찍 오는 경우 한해에 의하여 노지재배는 고사될 우려가 있고, 중부지역에서는 비닐하우스를 이용한 잎들깨 채종재배가 가능하였다.
