The root of Rumex crispus(Polygonaceae) has been used as one of many oriental medicines ofr the treatment of cathartics, juandice and skin diseases etc. Recently, it is reported as one of anticancer agents and a remedy of acute hepatitis in many traditional medicines. Also, the seed of this plant has been used as a folk medicine for the treatment of digestion problems, liver diseases and many sorts of tumors. In this study we have collected the seed of this plant in rural area and investigated the efficacy of hepatoprotective activity from liver cell damage induced by carbon tetrachloride on mice with methanol extracts, ethylacetate and butanol fractions of this plant

Persicaria lapathifolia Gray (Polygonaceae) is a common weed in Korea. This plant and other Persicaria species including P. orientale and P. pubescens have been used as an analgesic and stomachic as well as for the treatment of rheumatoid arthritis and malaria. During the screening program of plant extracts, MeOH extract of P. scabrum showed anticomplement activity and the MeOH extract was partitioned with hexane, chloroform, ethyl acetate, and buthanol. EtOAc fraction showed strong activity and activity guided separation yielded eight flavonoids. Two known galloylated and a novel ferulloylated flavonoid glycosides showed strong anticomplement activity. Other flavonoid glycosides, kaempferol 3-O-${\alpha}$-$\sub$L/-arabinopyranoside, kaempferol 3-O-${\beta}$-$\sub$D/-glucopyranoside, kaempferol 3-O-${\beta}$-$\sub$D/-galactopyranoside, quercetin 3-O-${\alpha}$-$\sub$L/-arabinopyranoside, quercetin 3-O-${\beta}$-$\sub$D/-glucopyranoside, quercetin O-${\beta}$-$\sub$D/-galactopyranoside did not showed anicomplement activity.

About 117 weed species composed of 44 annuals, 26 biennials, and 47 perennials belonging to 36 families were identified from golf fields in both Anyang an Taegu country clubs on May and September, 1989. Graminae was the most widely occuring family covering 21 species, followed by 14 species in compositae, 8 species in leguminosae, polygonaceae and caryophyllaceae respectively, and 5 species in cyperacae etc. The highest numbers of weed species occured in the rough area in golf fields, followed by tee, fairway and green area in orders. The dominant weed species in golf fields based on importance value and frequency were Digitaria Sanguinalis, Poaannua, Polygonum aviculare, Trifohum repens, Plan tago asiatica, Capsella bursa-pastoris Rumx acetocella and Kyllinga brevifolia.

Polyphenol QGR (quercetin 3-O-beta-(2"-galloyl)-rhamnopyranoside) was isolated from Persicaria lapathifolia (Polygonaceae). In this study, we investigated inhibitory effects of QGR and its building blocks (quercitrin, quercetin and gallic acid) on superoxide anion and NO productions in unopsonized zymosan-stimulated murine macrophages Raw264.7. QGR and quercetin showed potent inhibitory effects on unopsonized zymosan-induced superoxide anion production with IC50 values of 3.2 uM and 4.8 uM, respectively. (omitted)

The present study was conducted during the period July 18-August 11, 1981, at the four industrial complexes(Pohang, Ulsan, Onsan, and Yeochon) using the naked eye method. The study included the survey of plant species growing within a 2km from the area of pollution source, selection of plants tolerant to air pollution and effects of pollution on their growth. The results obtained are as follows; 1) Vascular plants surveyed as to industrial complexes consist of 90 families, 6 subfamilies, 213 genera and 290 species. Major plant families and species for each area are as follows: 1) Pohang area: 54 families, 102 genera and 126 species Leguminosae(16) Graminae(11), Compositae(9) Rosaceae(9) 2) Ulsan area: 61 families, 131 genera, and 158 species Compositae(17) Gramineae(16) Leguminosae(15) Rosaceae(9) Polygonaceae(9) Solanaceae(6) 3) Onsan area: 46 families, 98 genera, and 158 species Compositae(12) Gramineae(12) Leguminosae(12) Rosaceae(6) Polygonaceae(6) 4) Yeochon: 71 families, 150 genera, and 188 species Rosaceae(15) Leguminosae(15) Compositae(14) Graminese(14) Polygonaceae(8) Salicaceae(6) 2.

The Polygonum amphibium complex (Poygonaceae) is a highly polymorphic taxon that can grow in aquatic environments as well as in moist terrestrial habitats. Aquatic and terrestrial plants of the P. amphibium complex vary significantly in morphology and exhibit very complicated patterns of morphological variation, resulting in the description of numerous infra-specific taxa. Principal components analysis of 107 individuals of the P. amphibium complex from Asia and North America using 11 morphological characters showed that the aquatic plants can be discerned from the terrestrial plants by leaf size, shape, and petiole length. In contrast, both aquatic and terrestrial plants collected from the same population or locality shared identical sequences in the matK, psbA-trnH IGS, rbcL-accD IGS and trnL-trnF regions of the chloroplast DNA (cpDNA), suggesting that aquatic and terrestrial forms of the P. amphibium complex are not genetically diverged; morphological differences between the two forms are probably due to the differences in environmental conditions of the habitats. In addition, results from the morphological analysis and the maximum parsimony analysis of the cpDNA data set revealed that the plants from Asia including Korea, Japan, China, Mongolia and Russia Far East are diverged from those in North America and Europe, suggesting that the Asian populations should be recognized as a distinct variety, P. amphibium var. amurense Korsh.

Rhei Rhizoma (RR; 大黃) consists of the underground parts (rhizome and root) of Rheum officinale Baill. and Rheum palmatum L. (Polygonaceae), and is widely used in Southeast Asian folk medicine to alleviate liver and kidney damages. In this study, we investigated into the efficacy and mechanism of RR water extract in supporting neuronal survival in a hypoxia model of cultured rat hippocampal neurons. RR exhibited no cytotoxicity up to 10 ${\mu}g$/ml and exhibited neurosupportive effects at 2.5 ${\mu}g$/ml in normoxia. When RR was added to the culture media on 10 days in vitro (DIV10) and given a hypoxic shock (2% $O_2$/5% $CO_2$, 3 hr, $37^{\circ}C$) on DIV13, RR exhibited neuroprotective effects on 5 days post-shock. $H_2DCF$ stainings indicated that RR effectively prevents ROS production in both normoxia and hypoxia. JC-1 stainings showed that RR prevents dissipation of MMP in hypoxia. These results indicate that RR protects neurons by suppressing ROS production and MMP loss.
