The mutagenic and antimutagenic activities of juices from 20 common edible wild herbs found in Korea were investigated using the spore-rec assay and Ames test. The juices of Hemerocallis fulva and Capsella bursapastoris exhibited a little induction or inhibition of mutagenesis in the presence of selected metal ions, but juices of most edible wild herbs did not affect on the mutagenesis in the spore-rec assay. In the other hand, all of the juices strongly inhibited the mutagenesis induced by benzo[a]pyrene, 2-amino-fluorene, and 3-amino-1,4-dimethyl-5H-pyridol tested on Salmonella typhimurium TA98 or TA100 in the presence of S-9 mix. The antimutagenic effects increased as the concentration of the mutagens increase. The results suggest that concentration of samples or types of various mutagen interact to affect the antimutagenic potential of the juices in the TA98 and TA100 strain.

This study was aimed to screen edible herbs which control the composition of intestinal microflora. With in vitro experiments, we screened the water or ethanol extracts of about 60 edible herbs and wild plants in terms of the inhibition activity on the growth of the harmful Clostridium perfringens and growth promoting activity for the beneficial Bifidobacteria. The water extracts of mugwort and small water dropwort inhibited the growth of Cl.perfringens both in agar diffusion method and broth culture. On the other hand, the water extracts of petasites, mugwort, yellow day-lily and bitter cress have shown the promotion effect on the growth of Bifidobacterium longum. In the culture test using human feces as starter, the extracts of the above selected herbs increased the population of Bifidobacteria and Lactobacillus while they reduced the numbers of Cl.perfringens and E.coli.

With well-being boom recently, the common people, but not experts, are increasingly taking in them directly by picking wild herbs. However, only experts can distinguish between edible vegetables and poisonous herbs from the wild herbs. Especially, it is not even easy for experts to distinguish them only by looking into buds in spring without flowers or fruit. So, sometimes many patients are being carried into the emergency room by the toxic symptom after taking by misunderstanding the poisonous herbs as edible vegetables. For herb intoxication as well as drug intoxication, what kinds of vegetables patients took in, and when and how much they took in them are important information for curing. Of course, in the case of intoxicating in the wild herbs, the patients can have a lot of symptoms and sings-hemodynamic alteration and abnormal neurologic sign as well as gastrointestinal symptoms-according to the kinds of herbs which they took in. Therefore, it is difficult to find the kinds of herbs which they took in through the specific symptoms. Recently we experienced a case with showing typical anticholinergic symptoms after ingestion of Scopolia japonica. As a result, the publicity activities about the wild plants needs because if the person without their previous knowledge take in the poisonous herbs, serious side effects can be produced..

대부분의 산채는 한 계절에만 생산되므로 연중 공급될 수 있는 건조 상태로 유통된다. 건조 산채에 필요한 제품화 기술로는 재수화시간 단축기술, 간편 즉석 산채와 즉석 조리 산채의 제품화 기술 등이다. 식품소재로의 응용분야 확대를 위해서는 산채를 미분화하여 일반식품소재화 하는 방법이 적합하다. 그러나 전분함량이 낮은 산채류는 분쇄력이 가해지기 어려워 공업 규모에서의 미분말 제조가 곤란하고 비용적인 문제로 용도가 제한된다. 따라서 산채의 식품소재화 공정에서 중요한 핵심기술은 분쇄이므로 저비용에서의 미분말 제조기술 개발이 필요하다.

Recently, some patients have visited the emergency department for treatment of different symptoms of acute poisoning after intake of unidentified herbs, which can be mistaken for wild edible greens, because wild edible greens are good for health and contain vitamins, enzymes, minerals, fibers, and anticancer materials. Winter or early spring, is extremely high, with rapid onset of severe symptoms of poisoning. There have been no reports of poisoning by SymplocarpusRenifolius in Korea, however, we report on three severe cases involving patients who experienced cardiogenic shock with nausea, vomiting, abdominal pain, chest discomfort, dizziness, numbness, and general weakness.

With a recent well-being boom, our interest in chemical-free vegetables is also increasing. So, some people are trying to take in wild plants chosen by themselves. However, others often come to their rescue in an emergency department after eating them, caused by their misunderstanding poisonous herbs as edible vegetables. We have ever seen two persons carried into the emergency department with bradycardia and shock incurred by his intake by confusion between Caltha palustris and Ligularia fischeri lately. There were symptoms such as epigastric pain, nausea, vomiting and so on in their cases, and the symptoms of bradycardia and hypotension continued. Owing to sustained bradycardia and hypotension states, we applied a dopamine to a patient, and then the in-patient left the hospital two days later. We presumed the cause of the two symptoms appeared in two cases to be a saponin in Caltha palustris. For that reason, if someone has the bradycardia and hypotension symptoms from an unknown cause after taking in wild plants, they have to consider a toxication by the Caltha palustris. Therefore, this paper focused on the issue that unexpected poisoning would have to be prevented by studying about wild plants much more and informing the toxic risk from the plants.

약용식물 6종을 메탄올로 추출한 다음, n-hexane층을 DMSO에 녹여 항산화 활성을 측정 비교하여 기능성 소재인 천연 항산화제로써의 활용 가능성을 조사하였다. DPPH를 이용한 라디칼 소거능 실험에서는 250 ${\mu}g/mL$ 농도에서 보골지가 대조군인 ascorbic acid에 비해 높은 유리기 소거능에 의한 항산화 활성을 나타냈다. 농도 500 ${\mu}g/mL$에서는 ascorbic acid가 가장 높은 항산화 활성을 보였다. ABTS 유리기 소거능 실험에서는 농도 증가에 따른 항산화 활성이 DPPH assay와 상반된 결과를 나타냈고, 특히 보골지의 항산화 활성이 대조군인 ascorbic acid보다 유의적으로 높게 나타났다. DPPH 라디칼, ABTS 유리기 소거능 실험 결과 공통적으로 우수한 것으로 조사 된 약용 식물은 반지련, 보골지이며 500 ${\mu}g/mL$ 이상의 농도에서 ascorbic acid와 유사한 90% 활성을 보였으며 750 ${\mu}g/mL$ 농도에서는 ascorbic acid 보다 우수한 유리기 소거 활성을 보였다. 따라서, 반지련과 보골지는 항산화 활성이 우수하므로 천연 식물소재로 이용하기에 적합하며, 천연물의 추출 부위, 용매, 추출 조건에 따라 다양한 항산화 활성 능력을 기대 할 수 있으므로 천연 항산화제로서의 응용 가능성 또한 있을 것으로 사료된다.

Purpose: With the recent boom in 'eating healthy', many adults are interested in dieting to prevent future diseases. However only well trained experts can distinguish between what are edible vegetables and herbs from their poisonous look-alikes. In cases where a patient unknowingly ingests a poisonous herb, is caught off guard by the poisonous side effects that occur because of their lack of knowledge of what they have ingested. This paper will focus on the need to educate the public about the risks involved with ingesting wild vegetables and herbs and study the emergency diagnosis and treatment of poisoned patients that enter the emergency room. Method: This study was done in the spring of 2004 (from March to May) in the Kangwon Young-Seo districts of Korea. 15 subjects used in this study, entered the emergency room showing signs of toxic symptoms. Data was collected by examining subject's records. Additional data was collected by collaborating with physicians in the hospital that diagnosed and treated the subjects. Identifying the poisonous vegetable or herb is the first step to proper diagnosis and treatment. Subjects admitted to the emergency room, underwent a battery of tests: laboratory examination, ECG, radiological exam and etc. Results: The demographics of the study encompassed subjects with the average age of $50{\pm}19$ years old. There were 10 men and 5 women. Common symptoms of this study included; gastrointestinal symptoms such as nausea, vomiting, epigastric pain and so on. In the case of Caltha palustris ingestion, additional symptoms were present; bradycardia and hypotension which lasted for a long time. While cases that ingested Scopolia parviflora had little effect on vital signs but manic episodes lasted for about three days. Veratrum patulum ingestion showed signs of bradycardia and hypotension but contrary to Caltha palustris recovery was shorten by treating with dopamine. However, dizziness, headache and paresthesia of the extremities continued for a long time. Finally Sium ninsi ingestion showed visual disturbance, paresthesia of the extremities, dizziness as their initial symptoms. Conclusion: The risks involved with ingesting wild plants without the proper knowledge can lead to serious side effects and steps need to be taken to educate the public. In addition, all emergency physicians need to have a working knowledge of the symptoms and signs associated with ingesting toxic wild plants and need to treat accordingly.
