Rumex species (Polygonaceae) is widely distributed in Korea and its little sprout has been used as wild greens. The roots of Rumex sp. are used as a substitute for Rhei Rhizoma in Korea for its antipyretic and laxative properties. For the purpose of researching the value of Rumex sp. plants as natural resources, pattern recognition for the analysis of those plants was conducted using HPLC method. Two anthraquinone compounds, chrysophanol and emodin, were isolated from Rumex crispus to use standards. Chrysophanol and emodin from R. crispus were detected at retention time of 14.96 and 12.21 min, respectively. These compounds were detected from Rhei Rhizoma and all Rumex sp. plants. The content of chrysophanol of R. conglomeratus was higher than any other Rumex sp. plants. The amount of emodin was much higher from R. crispus than any other Rumex sp. The HPLC patterns of Rumex sp. are similar to that of Rhei Rhizoma, so they have something valuable as natural resources.

The extract and fractions of Rumex acetosa (Polygonaceae), a Korean medicinal plant, were examined for their cytotoxicities against five cultured human tumor cell lines, i.e. A549 (non-small cell lung), SK-OV-3 (ovary), SK-MEL-2 (melanoma), XF498 (central nerve system) and HCY15 (colon), using the SRB (sulforhodamine-B) method in vitro and antimutagenic activities by Ames test with Salmonella typhimurium TA98 and TA100 and SOS chromotest with E. coli PQ37. Among the tested samples, the methylene chloride fraction strongly inhibited the proliferation of each examined tumor cell line with $IC_{50}$ values ranged from 13.2 to $18.7\;{\mu}g/ml$ and showed potent antimutagenic activities with 96.1% and 96.7% at the concentration of 1 mg/plate against the mutagens, NPD and sodium azide, respectively. Its antigenotoxic activity was also very effective at the final concentration of $10\;{\mu}g/reaction$ tube against the mutagens, MNNG and NQO by SOS chromotest.

The antidiabetic-activity-guided fractionation and isolation of the $80\%$ EtOH extracts obtained from cultivated Korean Rhubarb rhizomes (Rheum undulatum, Polygonaceae) led to the isolation and characterization of one stilbene, desoxyrhapontigenin(1) and two anthraquinones, emodin (2) and chrysophanol (3). Their structures were established by chemical and spectroscopic methods. Compounds 1, 2, and 3 inhibited postprandial hyperglycemia by 35.8, 29.5, $42.3\%$, respectively.

In the course of phytochemical studies of Rumex acetosella L. (Polygonaceae), the MeOH extract of the whole plants was fractionated with $CH_2Cl_2$ and $H_2O$, and the $CH_2Cl_2$ layer was fractionated again with 90% MeOH and hexane. Whereas $H_2O$ layer was fractionated with EtOAc and then with n-BuOH again. By repeated column chromatography, compound 1 was isolated from the 90% MeOH fraction, compounds 1, 2, 3, 4 and 5 were from the ethylacetate fraction, and compound 5 was from the n--BuOH fraction. On the basis of physico-chemical, spectroscopic evidences and in comparison with authentic samples, the structures of them were confirmed to emodin, citreorosein, $chrysophanol-8-O-{\beta}-D-glucopyranoside$, luteolin and $luteolin-7-O {\beta}-D-glucopyranoside$.

The achene morphology of 21 taxa of Persicaria sect. Cephalophilon including the related taxa of Koenigia (Polygonaceae) was examined using stereo microscopy and scanning electron microscopy to evaluate its diagnostic values and taxonomic implications. The outlines of achene were narrowly ovoid to broadly ovoid in general, and elliptic achenes were observed in Koenigia taxa, with the achene shape being biconvex or trigonous. The size of the P. sect. Cephalophilon taxa ranged from $0.93-3.55{\times}0.80-2.31mm$ and the size of examined Koenigia taxa ranged from $1.10-1.84{\times}0.79-1.02mm$. The smallest achenes in P. sect. Cephalophilon were observed in P. humilis and the largest achenes were found in P. chinensis var. chinensis. Furthermore, infraspecific taxa of P. chinensis had relatively large achenes compared to other taxa within the section. Most taxa of P. sect. Cephalophilon had dull achenes, while four taxa had glossy achenes (P. capitata, P. runcinata var. runcinata, P. runcinata var. sinensis, and P. sinuata). Four types of surface patterns (smooth, tubercles, small pits, and irregular ridge) were observed, and the tubercles were divided into two subtypes according to the grouping and distribution pattern. The achene morphology of P. sect. Cephalophilon is described and compared, and its taxonomic implications are also discussed.

Patterns of morphological variation in Polygonum setaceum Baldwin ex Elliott are examined, and the taxonomic significance of the varieties recognized by Fernald is reevaluated. The diagnostic characters used to differentiate the varieties in P. setaceum demonstrate virtually continuous variation, and broad geographic intergradation is recognized. Principal components analyses of major morphological characters also fail to separate the varieties. These results strongly suggest that recognition of var. setaceum, var. interjectum, and var. tonsum by Fernald is unwarranted.
