국화과에 속하는 미기록 귀화식물 2종이 강원도와 제주도에서 확인되었다. 미기록속인 미역취아재비속(Euthamia Nutt.)에 속하는 미역취아재비[Euthamia graminifolia (L.) Nutt.]가 강원도 인제군에서 발견되었다. 이 종은 선점이 있고 전연인 잎과 맥이 없는 통상화관에 의해 미역취(Solidago japonica Kitam.) 및 미국 미역취(S. gigantea Aiton)와 구별된다. 국명은 미역취와 유사하여 '미역취아재비'로 신칭하였다. 또한 미국풀솜나물[Gamochaeta pensylvanica (Willd.) Cabrera]이 제주도에서 발견되었다. 이 종은 개화기에 없어지는 근생엽과 더 짧은 내총포에 의해 자주풀솜나물[G. purpurea (L.) Cabrera]과 구분된다. 국명은 종소명을 고려하여 '미국풀솜나물'로 신칭하였다.

우리나라의 자원식물 중 식용으로 이용할 수 있는 식물종에 대한 연구로서 식용자원의 발생 이황에 대한 연구와 유전자원 수집을 통해 얻어진 결과는 다음과 같다. 1. 우리나라에 발생하는 식용 자원식물 중 74 개과에 속하는 609종의 발생이 확인되었다. 2. 식용 자원식물의 수에 다른 과별 순위는 국화과＞백합과＞십자화과＞콩과＞장미과＞산형과＞화본과＞석죽과 순으로 나타났다. 3. 국화과, 십자화과, 백합과에 속하는 대부분의 식용식물은 경엽부를 채소로서 이용하고 있었으며, 장미과의 식물과 콩과 식물 중 일부는 과실이나 종자를 식용 자원으로 이용할 수 있었다. 4. 재배하는 작물종과 식물분류학적으로 근연관계에 있는 종의 수가 많은 화본과 식물은 직접 식용으로 이용할 수 있는 종의 수가 극히 적었다. 5. 수집된 종자들의 발아률은 종마다 다양하여 자원식물의 식용을 위해서는 발아율의 낮은 종의 발아율 개선에 대한 연구가 선행되어야 한다.

세스퀴테르펜 락톤(Sesquiterpene lactones; STL) 화합물은 테르페노이드의 일종으로 주로 국화과에서 발견이 되고 강한 세포 독성을 나타내는 생리학적 특성을 지니고 있다. 이러한 세스퀴테르펜 락톤은 강한 세포 독성으로 인해 연구가 미미하였으나, 최근 화학적 변형을 통해 독성이 적은 형태로 합성하여 새로운 의약품 개발로서의 연구가 활발히 진행되고 있다. 세스퀴테르펜 락톤 화합물인 artemisinin 및 mipsagargin 화합물은 현재 말라리아 및 종양성장에 대한 약물로 사용되고 있다. 또한 항산화, 간보호, 항바이러스, 항균, 항종양 및 항노화 등의 생리활성 효능이 보고되어 있으며, 종양세포에서 자멸사를 유도하여 항암제로서의 연구가 진행되고 있다. 본 연구에서는 세스퀴테르펜 락톤 화합물인 artemisinin, costunolide, thapsigargin, arglabin, parthenolide, alantolactone, cynaropicrin, helenalin, 및 santonin의 생리활성 효능에 대한 연구 동향을 검토하고자 한다.

The Kashmir Himalaya, known for its indigenous and endemic flora, also provides home to a large number of exotic plants, which exhibit a wide taxonomical and distributional stretch. Although, some preliminary studies have been carried out in the region on some aspects of its exotic flora, the inventorization and documentation of its exotic have received a little or negligible attention. There is a lot of scope of these exotic plant species in Kashmir valley, but lack of authentic identification has been as a big hurdle in their scientific management. It is in this backdrop that the present floristic study was carried out to identify, inventorize, document and characterize the exotic plant species grown in the Valley. The present study has revealed that Kashmir Valley grows 317 exotic plant species, which belong to 209 genera in 85 families. Dicotyledons are the largest group, represented by 252 species in 163 genera and 67 families. Monocotyledons comprise 52 species in 37 genera and 13 families. Gymnosperms are the smallest group, with 13 species distributed in 9 genera and 5 families. Asteraceae is the largest family containing 33 exotic species.

The numbers of vascular plants were summarized as 388 taxa including 75 families, 246 genera, 360 species, 4 subspecies, 19 varieties, 2 forms and 3 hybrids. The most families of taxa were Poaceae (59 taxa), Asteraceae (47 taxa), Fabaceae (27 taxa), Rosaceae and Cyperaceae (20 taxa, respectively), and Polygonaceae and Brassicaceae (15 taxa, respectively). The rare plant was Aristolochia contorta Bunge, and the Korean endemic plants were 4 taxa, such as Populus × tomentiglandulosa T.B.Lee, Salix koriyanagi Kimura ex Goerz, Lespedeza maritima Nakai, and Weigela subsessilis (Nakai) L.H.Bailey. The specific plants by floristic region found in this site were 13 taxa comprising 8 taxa of grade I, 4 taxa of grade III, and 1 taxon of grade IV. The naturalized plants were 73 taxa, such as Fallopia dumetorum (L.) Holub, Persicaria orientalis (L.) Spach., Potentilla supina L. var. ternata Pterm., and so forth. The invasive alien plants were 6 taxa, such as Rumex acetosella L., Sicyos angulatus L., Solanum carolinense L., Ambrosia artemisiifolia L., Lactuca serriola L., and Symphyotrichum pilosum (Willd.) G.L.Nesom..

The aim of this study is to collate all available data on experiments reporting the antiproliferative, cytotoxic effects of plants and natural products in Morocco in the last two decades. A bibliographic investigation was carried out by analyzing recognized books and peer-reviewed papers, consulting worldwide accepted scientific databases (Scirus, Embase, HighWire, MEDLINE/PubMed, LILACS, Ovid, ScienceDirect, SciELO, Google Scholar). We used medical subject heading terms and the words 'anticancer', 'antiproliferative', 'antineoplastic', 'antitumoral', 'cytotoxic', 'Morocco', to identify relevant articles. Moroccan plants with attributed anti-cancer properties studied as plant extracts that have been evaluated for cytotoxic effects, antitumoral effects, plants with active compounds tested on cancer cell lines, and plants with active compounds that have been assayed on animal models were chosen for this research. In the present study, interest is focused on experimental research conducted on medicinal plants, particularly those which show antiproliferative or cytotoxic activities alongside bioactive components. A total of 20 plant species belonging to 12 families have been identified as active or promising sources of phytochemicals with antiproliferative properties. The plant families, which cover all the species studied in this field, are Lamiaceae (7 species) and Asteraceae (4 species); the most studied species being Argania spinosa (Sapotaceae) and Arisarum vulgare (Araceae), Thymus Genus (Labiateae) and Peganum harmala (Zygophyllaceae). Based on the search results, it is recommended to increase the number of experimental studies and to begin conducting clinical trials with Moroccan plants and their active compounds selected by in vitro and in vivo activities.

In this study, the effects of a methanol (MeOH) extract of Carduus crispus L. (Asteraceae) on adipogenesis was investigated in 3T3-L1 cells. To differentiate preadipocytes to adipocytes, confluent 3T3-L1 preadipocytes were treated with a hormone mixture, which included isobutylmethylxanthine, dexamethasone, and insulin (MDI). The methanol extract of C. crispus significantly decreased fat accumulation by inhibiting adipogenic signal transcriptional factors in MDI-induced 3T3-L1 cells in a dose-dependent manner. In MTT assays and on PI-staining, methanol extract of C. crispus inhibited the proliferation of 3T3-L1 cells during mitotic clonal expansion (MCE). The anti-adipogenic effect of the Carduus extract seemed to be associated with the upregulation of extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (MAPK) pathways within the first 2 days after MDI treatment. These results suggest that methanol extract of C. crispus might be beneficial for the treatment of obesity.

Ixeris dentata (ID, family Asteraceae), called Seumbakuy in Korea, was fermented with lactic acid bacteria (LAB) and their antiallergic activities were investigated. Fermentation of ID with Bifidobacterium breve or Lactobacillus acidophilus increased its inhibition of degranulation in RBL-2H3 cells induced by the IgE-antigen complex. Oral administration of these extracts to mice inhibited the passive cutaneous anaphylaxis (PCA) reaction induced by the IgE-antigen complex and scratching behaviors induced by compound 48/80. The fermented ID more potently inhibited the PCA reaction and scratching behaviors than the non-fermented one. These extracts also inhibited mRNA expression of TNF-${\alpha}$ and IL-4, as well as NF-${\kappa}B$ activation in RBL-2H3 cells induced by the IgE-antigen complex. These findings suggest that LAB fermentation improves ID-mediated inhibition of IgE-induced allergic diseases such as rhinitis and asthma, and that ID works by inhibiting degranulation and NF-${\kappa}B$ activation in mast cells and basophils.

A new sesquiterpene lactone dimer [1], together with five known compounds (2-6), was isolated from the flowers of Inula britannica. The structures of these compounds were established by extensive spectroscopic studies and chemical evidence. The inhibitory activities of these isolated compounds (1-6) against human neutrophil elastase (HNE) were also evaluated in vitro; compounds 1 and 6 exhibited significant inhibitory effects against HNE activity, with $IC_{50}$ values of 8.2 and $10.4{\mu}m$, respectively, comparable to that of epigallocatechin gallate (EGCG; $IC_{50}=10.9{\mu}M$). In addition, compounds 3 and 5 exhibited moderate HNE inhibitory effects, with $IC_{50}$ values of 21.9 and $42.5{\mu}M$, respectively. In contrast, compounds 2 and 4 exhibited no such activity ($IC_{50}$ > $100{\mu}M$). The mechanism by which 1 and 3 inhibited HNE was noncompetitive inhibition, with inhibition constant ($K_i$) values of 8.0 and $22.8{\mu}M$, respectively.
