To search for the aldose reductase (AR) inhibitors from Korean folk plants, the inhibition of rat lens AR in vitro using the methanol (MeOH) extracts from Korean folk plants in Chungcheong Province was investigated. Among Korean folk plants tested, the MeOH extract of Persicaria longiseta showed highest inhibition of AR ($IC_{50}$ value, $5.14{\mu}g/ml$). Consequently, P. longiseta has a possibility of new natural resources for the development of AR inhibitor for the prevention of diabetic complications.

The inhibition of rat lens aldose reductase (AR) in vitro using methanol extracts from Korean folk plants was investigated. Among them, the extracts of Saussurea grandifolia and Rumex crispus showed highest inhibition of AR. $IC_{50}$ values of the extracts from S. grandifolia and R. crispus were demonstrated 0.07 and 0.05 mg/ml, respectively. Korean folk plants such as S. grandifolia and R. crispus has a possibility of new natural resources for the inhibition of AR.

To search for the aldose reductase (AR) inhibitors from Korean folk plants, the inhibition of rat lens AR in vitro using the methanol (MeOH) extracts from Korean folk plants was investigated. Among fifty four Korean folk plants tested, the MeOH extract of Cedrela sinensis showed highest inhibition of AR ($IC_{50}$ value, 2.52 ${\mu}g/ml$). The plant C. sinensis has a possibility of new natural resources for the development of AR inhibitor for the prevention of diabetic complications.

This study was carried out in order to catalogue the folk plants of 7 counties and cities of northern region of Chungcheongbuk-do from March to October, 2011. Based on the 626 survey sheets collected from 67 residents at 17 places of 7 counties and were subsequently analysed. The identified folk plants in the northern region of Chungcheongbuk-do consisted of a total 348 taxa; 98 families, 250 genera, 298 species, 5 subspecies, 38 varieties, and 7 forms. The use by its usage were: 223 taxa; edible, 123 taxa; medicinal, 4 taxa; dye, 2 taxa; aroma, 6 taxa; spice, 32 taxa; ornamental, 11 taxa; oil, 4 taxa; starch, 22 taxa; and others, respectively, so the edible use is the highest. The most useful part was the leaf, followed by fruit and root. The consistency comparison between the scientific and the local name were the highest in the 50's and the lowest in 80's.

Rumex crispus (Polygonaceae) is a well known perennial plant. which is called So-Ri-Jaeng-Yi. growing in the field and on the roadside. It has been used as a Korean Folk medicine in treating of acute and chronic cutaneous disease. cathartics, fever and jaundice. Also, the seed of this plant has been used as only a folk medicine for the treatment of digestion problems, liver diseases and many sorts of tumor. So we examined analgesic activity, anti-inflammatory activities and hepatoprotective activity using MeOH extraction and BuOH fraction in this plant. (omitted)

Korean folk medicine "Ggaenggaengipul" has beenused to dlear heat and treat chronic childfood mutitional impairment, diarrhea, jaundice, haemorrhoid, inflammation, anepithymia, nausea and egestion .The crude drug often used as a supstitute for the more expensive "Huang Lian " (황연) in Korea and China. With regard to the botainicla origic of " Ggaenggaenigipul" , it has never been studied pharmacognostically. To clarify botanical origin of " Ggaenggaegipul" , the morphological and anatomicla characteristics of the leaves, petiole, rhizoma, and radix of Jeffersonia dubia BENTH were studied.

This study was conducted during two separate periods, from April to December 2008 and from April to November 2013, to identify the folk plants growing in Jeollanam-do which are used daily. A total of 1,200 questionnaires were distributed to 120 residents living in 14 counties and cities. From the results of the survey, 172 taxa of folk plants (77 families, 153 genera, 154 species, 2 subspecies, 14 varieties, and 2 forma) were identified. By regions, the city of Suncheon yielded 82 taxa, followed by 67 taxa from Gurye county, 65 taxa from Hampyeong county, 64 taxa from Jangseong county, 62 taxa from city of Naju, and 61 taxa from Jangheung county. Uses of the identified folk plants were: as edibles (117 taxa), for medicinal purposes (66 taxa), tea (15 taxa), for starch (6 taxa) for vegetable fat and oil (3 taxa), for nectar (2 taxa), for sap (2 taxa), for spice (2 taxa), for aroma (1 taxa), for fiber (1 taxa), and others (14 taxa). Thus, edible and medicinal uses of the plants appeared higher than other uses. The consistency of the local names of plants with the standard botanical nomenclature was 23.2% (40 taxa), while the proportion of local plant names analogous to the standard names was 18.6% (32 taxa). The consistency of the local plant names with the same plants in different cities and counties was 28.5% (49 taxa) and the proportion of local plant names analogous to each other in this category was 25.6% (44 taxa). Therefore, 54% of the folk plants growing in Jeollanam-do are known by location specific names. The usage types of the local folk plants were mostly collected through verbal communications.

This study was carried out in order to catalogue the folk plants of 5 counties and cities of Chungcheongbuk-do Province from March to October, 2011. 429 pages of field notes relating to the folk plants were collected from approximately 92 local inhabitants and analyzed subsequently. The identified folk plants were of 173 taxa, composed of 150 species, 1 subspecies, 22 varieties and 129 genera under 56 families. Naturalized plants were included. The use by its usage was: 349 taxa; edible, 68 taxa; medicinal, 2 taxa; dye, 1 taxa; aroma, 4 taxa; spice, 1, taxa; ornamental, 3 taxa; oil, 1 taxa; starch, 18 taxa; others respectively, so the edible use is the highest. The most useful part was the leaf, followed by stem, and whole plant. The consistency comparison between the scientific name and the local name were the highest in the 50's and the lowest in 90's.

Korean folk medicine Bae Pung Dung has been used to cure a cold and jaundice. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of Bae Pung Dung, the morphological and anatomical characteristics of the leaves and stems of Solanum species growing in Korea, i.e. S. japonense Nakai, S. lyratum Thunb., S. nigrum L. were compared. As a result, it was determined that Bae Pung Dung was the whole plant body of Solanum lyratum and Solanum japonense.
