Objectives : The origin of Breeae Herba (So-gye) and Cirsii Herba (Dae-gye) is differently prescribed in Korean and Chinese modern pharmacopoeia. Since the similar morphological characteristics and chaotic plant names, moreover, the aerial part of Carduus crispus have been used as the Cirsii Herba. To develop a reliable method for correct identification of these herbal medicines and to evaluate the genetic relationship of these closely related plant species, we analyzed sequences of DNA barcode regions. Methods : Thirty-one samples of 6 medicinal plants (B. segeta, B. setosa, C. japonicum var. maackii, C. setidens, C. chanroenicum, and C. crispus) were collected from different habitate and nucleotide sequences of DNA barcode regions (rDNA-ITS, matK, and rbcL) were analyzed after amplification using appropriate primers reported in previous studies. The nucleotides of species-specific authentic marker and phylogenetic relations were estimated based on the entire sequences of DNA barcodes by the analysis of ClastalW and UPGMA, respectively. Results : In comparative analysis of DNA barcode sequences, we obtained specific nucleotides to discriminate the medicinal plant of Breeae/Cirsii Herba in species level and evaluated the phylogenetic relationship of these species. Futhermore, we identified distinct marker nucleotides enough to authenticate respective species. These sequence differences at corresponding positions were avaliable genetic markers to determine the botanical origins of Breeae Herbal as well as Cirsii Herba. Conclusions : These marker nucleotides would be useful to identify the official herbal medicines by providing of definitive information that can identify each plant species and distinguish from unauthentic adulterants and substitutes.

Medicinal plants were screened for the inhibitory effects on human immunodeficiency virus type 1 pretense. Of the extracts tested, the strong inhibitory effects were observed in the acetone extracts of the pericarp of Camellia japonica. Camelliatannin H from the pericarp of C. japonica showed a potent inhibitory activity on HIV-1 pretense. Effects of the extract and compound from leaves of Zanthoxylum piperitum on the enzyme activities were investigated in the liver of bromobenzene-treated rats. The methanol extract and protocatechuic acid isolated from Z. pipetitum reduced the activity of aniline hydroxylase that increased by bromobenzene, while did not affect the activities of aminopyrin N-demethylase and glutathione S-transferase. The extract and protocatechuic acid recovered significantly the activity of epoxide hydrolase decreased by bromobenzene.

The aerial parts of Brassica juncea (Cruciferae) called by brown or oriental mustard have been widely used as a spice in food and also traditional folk medicine as stimulant, diuretic and expectorant agent. And Gatkimchi made of the aerial parts of this plant are very popular in Korea. The aerial parts of this plant was refluxed with MeOH and then fractionationed with $CH_2Cl_2$, EtOAc, n-BuOH and $H_2O$, successively. One higher alcohol compound and three flavonoids were isolated from the EtOAc fraction through silica gel and Sephadex LH-20 column chromatographies. Their structures were elucidated as n-hexacosanol(1), kaempferol(2), isorhamnetin $3-O-{\beta}-D-glucopyranoside(3)$ and isorhamnetin $3-O-(6'-O-acetyl)-{\beta}-D-glucopyranoside(4)$ by comparison of spectral data with those in references. And compounds 1 and 4 were firstly isolated from this plant.

Definitive identification of original plant species is important for standardizing herbal medicine. The herbal medicines Cynanchi Wilfordii Radix (Baekshuoh in Korean and Beishuwu in Chinese) and Polygoni Multiflori Radix (Hashuoh in Korean and Heshuwu in Chinese) are often misidentified in the Korean herbal market due to morphological similarities and similar names. Therefore, we developed a reliable molecular marker for the identification of Cynanchi Wilfordii Radix and Polygoni Multiflori Radix. We used random amplified polymorphic DNA (RAPD) analysis of three plant species, Polygoni multiflorum, Cynanchum wilfordii, and Cynanchum auriculatum, to obtain several species-specific RAPD amplicons. From nucleotide sequences of these RAPD amplicons, we developed six sequence characterized amplification region (SCAR) markers for distinguishing Polygoni Multiflori Radix and Cynanchi Wilfordii Radix. Furthermore, we established SCAR markers for the simultaneous discrimination of the three species within a single reaction by using multiplex-PCR. These SCAR markers can be used for efficient and rapid authentication of these closely related species, and will be useful for preventing the distribution of adulterants.

Korean ginseng (Panax ginseng C. A. Meyer) is an representative medicinal herb. It is classified as an adaptogen, helping the body to adapt to stress, improving stamina and concentration, and providing a normalizing and restorative effect. However, cultivation and breeding of the plant is very difficult because it requires at least 4-year cultivation from seed germination to root harvest.(중략)

Aldose reductase (AR) has been shown to play an important role in the development of the diabetic complications. To discover novel treatments for diabetic complications from natural sources, 59 Chinese herbal medicines have been investigated for inhibitory activities on AR. Among them, 10 herbal medicines, Catalpa fargesii (stem and leaf), Saussurea Laniceps(whole plant), Alnus nepalensis(stem and leaf), Swertia macrosperma (whole plant), Woodfordia fruticosa (stem and leaf), Elsholtzia bodinieri (whole plant), Elsholtzia fruticosa (whole plant), Rosa multiflora (fruit), Nardostachys chinensis (whole plant), Eurya groffii (stem and leaf) exhibited a significant inhibitory activity compared with 3,3-tetramethyleneglutaric acid (TMG) as positive control. Particularly, 4 herbal medicines, C. fargesii (stem and leaf), S. Laniceps (whole plant), A. nepalensis (stem and leaf), S. macrosperma (whole plant) showed two times more potent inhibitory activity than TMG ($5.37{\mu}g/ml$).
