Korean folk medicine "EJePiNaMu" has been used orally to cure neuralgia, rheumatism and common cold. To clarify the botanical origin of this crude drug, comparative anatomical studies were made on the branches of Zanthoxylum species growing wild in Korea, i.e. Z. coreanum, Z. piperitum, Z. piperitum var. pubescens, Z. planispinum, Z. schinifolium, Z. schinifolium var. inermis, Z. schinifolium var. microphyllum. As a result, it was clarified that "EJePiNaMu" was the branch of Zanthoxylum planispinum.

Obesity is the most common nutritional disorder in the developed world and has become a global epidemic in recent years. In this study, Zanthoxylum planispinum extracts (ZPE) were evaluated on the effect on inhibition of pancreatic lipase and lipid metabolism by oral treatment for 2 months in high-fed diet obesity-induced Balb/c mice. The ZPE showed pancreatic lipase inhibitory activity with $IC_{50}$ of $0.3{\mu}g/ml$. No significant difference in feed intake was observed among the groups. The high-fat diet-treated Z. planispinum extracts groups (HFD+ZPE, 100mg/kg) significantly decreased body weight compared to the high-fat diet vehicle groups (HFD, p<0.05). The high-fat diet-treated Xenical$^{(R)}$ groups (HFD+Xenical, n=10, 30mg/kg) also showed a significant reduction of body weight compared to HFD (p<0.05). Biochemical parameters (triglyceride, total cholesterol, and high-density lipoprotein cholesterol) in HFD plus ZPE diet groups were significantly lower than those of the HFD groups (p<0.05). These results indicated that ZPE more effectively suppressed the effects of HFD on body fat gain with the inhibitory effect on pancreatic lipase.

The vascular plants of this site was listed 360 taxa; 86 families, 229 genera, 311 species, 42 varieties and 7 forms. Specific plant species by floral region were total 40 taxa; 2 taxa(Crypsinus hastatus, Prunus yedoensis) in class V, Patrinia rupestris in class IV, 6 taxa(Elymus mollis, Carex laticeps, Poncirus trifoliata, Melia azedarach var. japonica, Koelreuteria paniculata, Crepiastrum lanceolatum) in class III, Cirsium schantarense in class II, 30 taxa(Lygodium japonicum, Pteris multifida, Phacelurus latifolius, Asparagus cochinchinensis, Ficus erecta, Machilus thunbergii, Zanthoxylum planispinum, Euphorbia esula, Mallotus japonicus, Cayratia japonica, Camellia japonica, Glehnia littoralis, Lysimachia fortunei, Messerschmidia sibirica, Ixeris repens etc.) in class I. The naturalized plants in this site were 14 families, 34 genera, 41 species, 1 varieties, 42 taxa and naturalization rate was 20.3% of all 207 taxa vascular plants. Based on the list of the rare plants by the Forest Research Institute, 2 taxa were recorded in the studied areas; Phacelurus latifolius, Crypsinus hastatus and based on the list of Korean endemic plants, 7 taxa were recorded; Populus tomentiglandulosa, Filipendula glaberrima, Prunus yedoensis, Forsythia koreana, Paulownia coreana, Weigela subsessilis, Carpinus coreana. So, wild plants disturbing ecosystem like Solanum carolinense and Ambrosia artemisiifolia var. elatior have been increasing, it needs continuing control and conservation measures on the plant ecosystem.

P-gp plays a critical role in drug disposition and represents a mechanism for the development of multidrug resistance. Flavonoids, a major class of natural compounds widely present in foods and herbal products, have been shown to inhibit P-gp. Therefore, the aim of this study was to identify new candidate chemosensitizers by screening various plant extracts. The ability of natural plant extracts to inhibit P-gp activity was assessed by measuring cellular accumulation of calcein AM, daunorubicin and vincristine in P-gp overexpressing MDCKII-MDR1 cells. Among more than 800 plant extracts, eight were found to inhibit P-gp activity. Curcuma aromatica extract produced greatest inhibition, followed by Curcuma longa and Dalbergia odorifera extracts. Extracts of Aloe ferox, Curcuma zedoariae rhizome, Zanthoxylum planispinum, and Ageratum conyzoides showed moderate inhibitory effects. Curcumin and quercetin exhibited similar inhibition of P-gpmediated efflux of daunorubicin and vincristine, and flavones had a lesser effect. When chemosensitizing effect was evaluated by measuring daunorubicin sensitivity to MDCKII-MDR1 cells in the presence of natural plant extracts, Curcuma aromatica showed the most potent chemosensitizing effect based on daunorubicin cytotoxicity. In conclusion, natural plant extracts such as Curcuma aromatica can potently inhibit P-gp activity and may have potential as a novel chemosensitizers.

This study is a survey of the flora distributed in Seocheon tidal flat wetland protected area of nearby island (Daejuk-do, Tokki-deung, Muk-do) and Yubo-do Seocheon-gun Chuncheongnam-do, Korea. The numbers of vascular plants were summarized as 231 taxa including 65 families, 167 genera, 204 species, 2 subspecies, 23 varieties and 2 forms. The halophytes were 33 taxa including 15 families, 29 genera, 29 species, 3 varieties and 1 form (Chenopodium album var. stenophyllum, Cnidium japonicum, Juncus haenkei and so on). The rare plants were 4 taxa including Pseudoraphis ukishiba (VU), Belamcanda chinensis (VU), Phacelurus latifolius (LC) and Polygonum bellardii (DD). The Korean endemic plants were 2 taxa including Salix pseudolasiogyne and Forsythia koreana. In the specific plants by floristic region were 24 taxa, a degree I were 19 taxa (Rhodotypos scandens, Zanthoxylum planispinum, Cynodon dactylon and so on), 2 taxa of a degree III (Elymus mollis and Asparagus oligoclonos), 3 taxa of a degree IV (Polygonum bellardii, Wisteria floribunda and Pseudoraphis ukishiba) and degree II, V were not found.

본 연구에서는 다양한 천연 추출물의 P-gp 저해능의 고속 탐색을 통하여 새로운 화학감작제 후보물질을 발굴하고자 하였다. P-gp 활성에 대한 천연 추출물의 저해능은 P-gp이 과발현된 L-MDR1 세포주를 이용하여 대표적인 P-gp 기질 약물인 calcein AM의 세포 내 축적 정도를 측정함으로써 평가하였다. 강황 및 울금은 가장 강력한 P-gp 기능 저해를 나타내었고, 이외에도 Mentrasto, 취호초, 봉출, Rakta chandan, 강진향, 소목, 노회 등의 순으로 P-gp 기능 저해능을 보였다. 이들 추출물에서 P-gp 저해능을 보이는 성분을 확인하기 위하여 LC/MS/MS 분석을 수행한 결과, 기존에 P-gp 활성을 저해한다고 잘 알려진 curcumin 이외에, 다양한 플라보노이드 화합물이 질량 스펙트럼 DB 검색을 통하여 확인되었다. In vitro 연구 결과를 통하여 상기의 천연 추출물이 P-gp 활성을 저해하는 성분을 함유하고 있음을 확인하였다. 향후 이들 천연 추출물의 화학감작제 후보물질로의 사용 가능성에 대한 in vivo 연구가 필요할 것이다.
