  • Aralia elata is found in mountain areas all over Korean peninsula. Aralia elata is the scientific name for Japanese angelica tree. The tree belongs to the family Araliaceae, commonly known as ginseng family. Bud sprouts from apical shoot tip of the plants are rich in flavor and thus mainly used for both folk medicine and vegetable. The stalks with apical buds are gathered in the early spring and planted in sandy soil or water in the greenhouse. The sprouting buds are then collected and sold as fresh vegetable. Although the plants have been used for food, they have been cultivated in a very small scale. In spring, local farmers just go around mountain areas to search the trees and gather the stalks as much as they get and sell them to the market. No conservation efforts have been made to stop the exploitation or to save the dwindling population. We tried to provide local farmers with the plants that may be used as an alternative to stalks from wild populations. This will hel! p conserve the wild populations. However, it is hard to propagate them either by conventional cuttings or by seed germination in a short period of time. Mass propagation using tissue culture systems have shown a great promise with several woody plants. Recently we developed a mass propagation technique via somatic embryogenesis system using mature and/ or juvenile explants for Aralia elata. Several factors affecting somatic embryogenesis system including SE(somatic embryo) induction, embryogenic callus proliferation, SE germination, plant regeneration and transplanting to field will be presented. And some problems arising for the somatic embryogenesis system will be also discussed.lso discussed.

  • The whole plants of Selaginella tamariscina, Orostachycis japonicus, the cortex of Ulmus mandshurica, and the wood of Alnus japonica have been used as folk medicine for treating cancer. The cytotoxic activity of these plants were tested using a calorimetric tetrazolium assay (MTT assay). S. tamariscina and A. japonica showed mild $IC_{50}$ value, comparing with O. japonicus and U. mandshurica. So, MeOH extracts of S. tamariscina and A. japonica were partitioned into $CHCl_3$, EtOAc and n-BuOH, successively. The $CHCl_3$, EtOAc and BuOH fractions of S. tamariscina and A. japonica showed low percent of survival against $P_{388}$ and $MKN_{45}$ cells respectively. To isolate active components, they were subjected to silica gel column chromatography. Compound I was obtained from EtOAc extracts of S. tamariscina and identified as amentoflavone by chemical and spectral analysis. Amentoflavone inhibited the survival of P388 cells dose dependently, while not clearly inhibited that of $MKN_{45}$ cells.

  • Many plant species are used in Malaysia in folk medicine for the treatment of cancer. This paper presents some of these species with details on other ethnopharmacological uses, the known bioactivities and some chemical constituents of each of the species given. It is normal practice in traditional medicine that one species of plant is used to treat various ailments. Thus the plant species listed are all used to treat cancer but have various other ethnophrmacological uses as well, some with few other uses and rest with many other uses. Information on bioactivities of each species resulting from tests on human and experimental animals are also given. Proven bioactivities give strength to ethnopharmacological claims on the efficacies of plant resources in the treatment of cancer and various other ailments but will but will not necessarily lead to the production of new pharmaceutical drugs. Many of the known chemical constituents of each species are given. This shows the richness and variety of chemicals containes in each of the species listed, The chemicals listed may or may not prove to be important in the pharmaceutical sciences but is an indication of what each species contatin in thrms of plant chemicals, It is a well known fact that many of the pharmaceutical prescriptions in present day use are of plant origin and semi-synthetic or fully synthetic chemicals produced using knowledge gained from studies of phytochemicals. Thus the paper presented will give useful information and also shows the richness of plant species that have high potentials for the development of anti-cancer resources from plants in Malaysia.

  • Genetic continuity of Digenea simplex outside the Atlantic waters remains less studied, despite its long exposure to oriental folk medicine and wide distribution in tropical waters. Mitochondrial COI-5P and plastid rbcL sequences and morphology were investigated for plants from Mexico and additional specimens from Japan. Two new species, Digenea mexicana and Digenea rafaelii, are described for plants that would previously have been recognized as D. simplex in Mexico. D. mexicana grows to 10.5 cm tall and has cylindrical axes, irregular or di-, trichotomous branches, simple to branched determinate branchlets with eight pericentral cells, and tetrasporangia on inflated upper parts of determinate branchlets. It occurs intertidally in Quintana Roo, Yucatan Peninsula. D. rafaelii grows to 5 cm tall and has cylindrical axes, irregular or di-, trichotomous branches, and simple determinate branchlets with ten pericentral cells. It occurs intertidally in the Gulf of California. Both COI-5P and rbcL sequences revealed the genetic discontinuity between D. mexicana and D. rafaelii.

  • We examined plants that were used as temple food in Jeju from May 2011 to January 2012. Thirty-six temples participated in the study, and there were 58 questionnaire respondents. Fifty-seven taxa were used as temple food, which belonged to 27 families, 51 genera, 55 species, and two varieties. The most commonly used family-based taxa were eight species of Compositae, six species of Cruciferae, and four species of Umbelliferae. Ten species of woody plants and 25 species of Jeju native plants were also used as temple food. The most useful part was the leaf, followed by the root, leaflet, and fruit. A patent search showed that most of the surveyed plants were covered by intellectual property rights. Forty-eight species had food-related patents, 34 species had cosmetics-related patents, and 38 species had medicine-related patents. The purchase and procurement of Jeju temple food plants usually depended on the market or plant cultivation rather than the use of the plants. Gathering of wild herbs for temple food has been performed on a limited basis. Therefore, collecting traditional knowledge for the use of Jeju plant resources should be conducted under different conditions rather than through a temple-related study.

  • Garlic(Allium sativum L.) is one of the oldest cultivated plants and has been used throughout the world as food supplement and folk medicine for thousands of years. In modem times a number of garlic derived products are introduced on the market as health food supplement in ever growing scale. In 1844 German chemist Wertheim investigated the garlic first time chemically and thereafter many kinds of organosulfur compounds were isolated and their biological activities were elucidated scientifically. The main biological activities are antibacterial, antifungal, antithrombotic, cholesterol-lowering, antineoplastic and hepatoprotective activities. Chemical works as well as therapeutic and preventive effects of garlic are reviewed.

  • The various species of aconitum contain diterpene (C-20) and norditerpene (C-19) forms of the natural alkaloid aconitine that cause neurologic, gastrointestinal, cardiovascular symptoms. In chinese medicine, these plants has been used as drugs to treat pain, dyspepsia, cerebrovascular disease, and so on. Because the therapeutic window is narrow, poisoning may occur from unintentional exposure, with a variety of toxic effects such as arrhythmia, hypotension, paresthesia, paralysis, nausea, vomiting, and abdominal pain. Aconitine-containing folk remedies are widely used in Korea. We encountered two cases of ventricular arrhythmia in patients who ingested tablets, known as 'Wha-Pung-Dan' made with aconitine extracts and were subsequently admitted to the ED. A 42 year-old man who took 35 tablets presented with ventricualr tarchycardia, and 40 year-old woman who took 40 tablets showed premature ventricular contractions. Both patients were discharged normally without any complications after three days.
