Atopic dermatitis (AD) were caused by localized hypersensitivity reaction to an allergen. Therefore, to reduce inflammatory response of AD had been developed that natural extracts and oils with anti-inflammatory activities. This study were investigated that anti-inflammatory effects of Malva verticillata L. oil induced by LPS with RAW 264.7 cells. We measured to production of NO and expression of COX-2, iNOS, TNF-${\alpha}$ by RT-PCR. The Malva verticillata L. oil had decreased the production of NO (p<0.05) and the mRNA level of iNOS in concentration dose dependent manner. In conclusion, this study have shown here may be of help to understand the action mechanism of the anti-inflammatory and we hope that Malva verticillata L. oil used in skin diseases such as AD.

A new daucosteryl derivative, verticilloside (1), was isolated from the seeds of Malva verticillata L. (Malvaceae). The structure was determined to be 3-O-[${\beta}$-D-(6'-linoleoyl)glucopyranosyl]-${\beta}$-sitosterol based on spectroscopic analyses ($^1H$ and $^{13}C$-NMR, DEPT, COSY, HMQC, and HMBC) and chemical reactions.

Stimulation of AMP-activated protein kinase (AMPK) signaling followed by increase of glucose uptake in L6 myotubes were studied with organic solvent extract of Malva verticillata (MV) seeds. Ethanol extract of M. verticillata seeds (MVE) significantly increased the phosphorylation level of AMPK, acetyl-CoA carboxylase (ACC), and glucose uptake in L6 myotube cells. The MVE was fractionated with n-hexane (MVE-H), chloroform (MVE-C), ethylacetate (MVE-E), n-butanol (MVE-B), and water (MVE-W). MVE-H (150 ${\mu}g$/ml) showed the highest phosphorylating activity and increased glucose uptake by 2.3-fold. Oral administration of MVE-H (40 mg/kg) for 4 weeks to type 2 diabetic (db/db) mice reduced non-fasting and fasting blood glucose levels by 17.1% and 23.3%, respectively. Phosphorylation levels of AMPK and ACC in the soleus muscle and liver tissue of db/db mice were significantly increased by the administration of MVE-H. MVE-H was further fractionated using preparative HPLC to identify the AMPK-activating compounds. The NMR and GC-MS analyses revealed that ${\beta}$-sitosterol was a major effective compound in MVE-H. Phosphorylation levels of AMPK and ACC, and glucose uptake were significantly increased by the treatment of MVE-S (${\beta}$-sitosterol) isolated from M. verticillata to L6 cells, and these effects were attenuated by an AMPK inhibitor (Compound C) pretreatment. These results, taken together, demonstrate that increased glucose uptake in L6 myotubes by MVE-H treatment is mainly accomplished through the activation of AMPK. Our finding suggests that the extract isolated from M. verticillata seed would be beneficial for the treatment of metabolic disease including type 2 diabetes and hyperlipidemia.

The fibrinolytic activities of soluble proteins extracted from seeds of Coix lacryma-jobi L., Carthamus tinctorius L. and Malva venicillata L. were studied. Fibrinolytic activity of extract from C. lacryma-jobi L. showed 1.3 times higher than plasmin used as positive control. The fibrinolytic enzyme was confirmed and extracted directly from seed of C. lacryma-jobi L. by a fibrin zymography. The protein was composed of a single polypeptide and its apparent molecular weight was found to be 7.8 kDa, as judged by SDS-polyacrylamide gel electrophoresis. The effect of temperature for the proteolytic enzyme activity were stabilized above $50^{\circ}C$ and then dramatically decreased. Also, the enzyme activity was clearly inhibited by APMSF, PMSF and TPCK, suggesting that it is a member of the chymotrypsin-like serine pretense. In addition, effects of gamma-irradiated on seed of each plants were revealed that 8 Gy and 64 Gy were higher than others. This result shown that gamma-irradiation of seeds were capable to increase the fibrinolytic activity. All these results suggest the pretense is a fibrinolytic enzyme belong to a family of chymotrypsin-like serine pretense.

This study investigated the effects of six metal oxide nanoparticles (NPs: CuO, NiO, TiO₂, Fe₂O₃, Co₃O₄, ZnO) on seed germination and germination index (G.I) for five types of seeds: Brassica napus L., Malva verticillata L., Brassica olercea L., Brassica campestris L., Daucus carota L. NPs of CuO, ZnO, NiO show significant toxicity impacts on seed activities [CuO (6-27 mg/L), ZnO (16-86 mg/L), NiO (48-112 mg/L)], while no significant effects were observed at > 1000 mg/L of TiO₂, Fe₂O₃, Co₃O₄. Tested five types of seed showed different sensitivities on seed germination and root activity, especially on NPs of CuO, ZnO, NiO. Malva verticillata L. seed was highly sensitive to toxic metal oxide NPs and showed following EC₅₀s : CuO 5.5 mg/L, ZnO 16.4 mg/L, NiO 53.4 mg/L. Mostly following order of toxicity was observed, CuO > ZnO > NiO > Fe₂O₃ ≈ Co₃O₄ ≈ TiO₂, where slightly different toxicity order was observed for carrot, showing CuO > NiO ≈ ZnO > Fe₂O₃ ≈ Co₃O₄ ≈ TiO₂.

This study was conducted to investigate the changes in contents of total flavonoid and total polyphenol of three leafy vegetables, spinach(Spinacia oleracea L.), chard(Beta vulgaris L.), whorled mallow(Malva verticillata L.) by various blanching times. Total flavonoid and total polyphenol contents of spinach were 21.01 and 25.58 mg/g, those of chard were 26.02 and 35.14 mg/g, and those of whorled mallow were 16.80 and 19.94 mg/g, respectively. Total flavonoid and total polyphenol contents of chard were the highest among the leafy vegetables. Total flavonoid and total polyphenol contents of leafy vegetables were decreased according to blanching time. Especially, total flavonoid content of chard showed significant loss of $15-30\%$ by blanching time. Total polyphenol content of whorled mallow showed loss of $37-39\%$, but the decrease was not significant.

We collected and examined germplasm resources of lettuces, edible chrysanthemums and mallows for organic farmers. We found that 3 genotypes (OL-51, OL-52, and OL-63) are suitable for organic cultivation. The main use of treatment for grey mold among eco-friendly pest control methods is helpful to increase efficiency of seed-gathering after collecting and evaluating a total of 64 kinds of lettuces-collected 43 South Korea local varieties, 8 kinds cultivated by the Highland Agriculture Research Center, 4 kinds of cultivated lettuces, and 9 kinds for sales- to choose appropriate kinds of lettuces for organic cultivation in South Korea. We chose those with more than 300 leaves (OC-18, OC-44, and OC-51) after evaluation of yield characteristics of a total of 62 edible chrysanthemums. We covered each genotype of seed of edible chrysanthemums when gathering the seeds by ourselves so as not to decrease the purity of each genotype. We chosed OM-38, OM-39, and OM-40 for their yield performance and germination rates among the total 41 genotypes of mallows. We selected 9 genotypes of lettuces, editable chrysanthemums and mallows with possibility of organic cultivation and found that they can be used permanently through self seed-gathering on organic farms.

The study attempts to assess the status, distribution, conservation and use value of Medicinal and Aromatic Plant (MAPs) in the Sagarmatha National Park. Altogether 62 species of MAPs belonging to 47 genera and 33 families have been recorded in the study area. 10 species, belonging to 9 families are categorized as the potential species. Out of the these species, most potential in local but threatened species are Allium hypsistum Stearn, Cordyceps sinensis Sacc, Dactylorhiza hatagirea Soo, Nardostachys grandiflora DC, Aconitum orochryseum, Ephedra gerardiana Wall. Ex. Stapf, Swertia multicaulis D. Don, Picrorhiza scrophulariflora Penne, Rheum australe. D. Don, Malva verticillataL and Swertia pedicallata Benerji. By analysis of data using Simpson's diversity index (SI) and Shannon weaver function (H'), there was high diversity (more heterogeneous) MAPs species composition in the Manjo Gate to Large Dobhan. (0.98349). Less diversity (less heterogeneous) MAPs species composition was in Tyanboche to Pangoche (0.90419). Similarly, the Shannon weaver function shows that in plots laying out in Mongla to Phorche are evenly distributed than others However, higher MAPs species (i.e., 31) was found in the way of Manjo Gate to Larja Dobhan than others.
