Ruspolia differens (Serville) (Orthoptera: Tettigoniidae) is a highly valued edible grasshopper species in Africa. However, the effects of plant diets on lipid content and fatty acid composition of R. differens are not well understood. We tested the effects of four diets on the total lipid content and fatty acid composition of R. differens. Sixth instar nymphs of R. differens were reared on one, and mixtures of two, three, and six natural plant inflorescences. Individuals collected from the field constituted a control treatment. We extracted lipids and analyzed the fatty acid methyl esters using gas chromatography-mass spectrometry. We analyzed if the total lipid content, body weight, and fatty acid composition differed among diets and between the sexes using two-way ANOVAs and a PERMANOVA model, respectively. The total lipid content and weight of R. differens did not differ among the diets. The nine common fatty acids were palmitic (mean across treatments, 26%), oleic (22%), palmitoleic (18%), linoleic (13%), stearic (7%), myristic (6%), myristoleic (4%), ${\alpha}$-linolenic (2%) and arachidic acid (1%). The composition of fatty acids and the proportion of essential fatty acids significantly differed among the diets. The proportion of essential fatty acids was highest in the control treatment (21%) but low in less diversified (one to three feed) diets (12-13%). This study demonstrates that the fatty acid composition in R. differens can be influenced through diet. Thus, with dietary manipulations, using local plants in Africa, it is possible to produce R. differens with preferred high quality essential fatty acids for human consumption.

The volatile aroma of fresh leaves is one of main factor in taste of all the edible green plants. The volatile aroma in almost edible green leaves are suggested as essential oil compounds. Ligularia fischeri, Synurus deltoides, Ligularia fischeri var. spiciformis and Aster scaber are one of the favourable edible green plants in Korea. In this study, volatile aroma compounds from Ligularia fischeri and Ligularia fischeri var. spiciformis species were analyzed by the SPME/GC/MSD method. Ligularia fischeri had 78 volatile aroma compounds such as D-limonene(20.28%), ${\alpha}$-pinene(dextro, 14.15%), L-${\beta}$-pinene(12.85%), 3-carene, ${\beta}$-cubebene(10.39%), etc. Ligularia fischeri var. spiciformis had 83 volatile aroma compounds such as D-limonene(36.97%), ${\beta}$-cubebene(13.95%), L-${\beta}$-pinene(13.38%), ${\alpha}$-pinene(dextro, 4.76%), caryophylle-ne(3.33%) etc. Conclusively, the commom volatile aroma compounds in Ligularia fischeri and Ligularia fischeri var. spiciformis leaves were D-limonene, ${\alpha}$-pinene, L-${\beta}$-pinene, ${\beta}$-cubebene, Caryophyllene, ${\alpha}$-farnesene, terpinolen. However, the composition and amount of volatile aroma compounds were very different between the two species.

Cholesterol acyltransferase (ACAT) catalyzes the acylation of cholesterol to cholesteryl ester with long chain fatty acids and ACAT inhibition is a useful strategy for treating hypercholesterolemia or atherosclerosis. Inhibitory effects on ACAT of the MeOH extracts prepared from 163 edible plants were evaluated. 15 species out of 163 species exhibited higher than 50% of inhibition on the hACAT-1 and 9 species exhibited higher than 50% of inhibition on the hACAT-2 activity at their concentration of $100\;{\mu}g/mL$.

Thirteen edible plants previously reported to show inhibitory activities on farnesyl protein transferase (FPTase) and phosphatase of the regenerating liver-3 (PRL-3) were evaluated for inhibitory activity on the proliferation of human umbilical vein endothelial cells (HUVECs). Four plant extracts, Oenothera erythrosepala, Perilla frutescens, Panicum miliaceum, and Quercus acutissima, significantly inhibited the proliferation of HUVECs induced by the basic fibroblast growth factor (bFGF) without cytotoxicity at 100 ${\mu}g/mL$. Myristica fragrans, Rosmarinus officinalis, and Syringa patula also showed inhibitory activity on the proliferation with only mild cytotoxicity.

The HCV gene was expressed in potato plants under the control of the constitutive CaMV 355 promoter or tuber-specific patatin promoter. Solanum tuberosum plants carrying a plant expression vector harboring the encoding region of HCV gene were generated by Agrobacterium tumefaciens-mediated in vitro transformation methods. The presence of HCV gene in the plant genome was detected by PCR and DNA hybridization experiments. We obtained the 5 lines of transgenic potato with the pMBPHCV construct and 4 lines of transgenic potato with the pATHCV construct. The HCV transgenic stably integrated into the potato genome, as well as their transcription. HCV mRNA was identified in leaf and tuber tissues of transgenic plants by Northern blot analysis. The transgenic potato plants produced the expected transcript, and the corresponding HCV protein accumulated in individual transgenic plants.

The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants (Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae frutcus) and we examined the effects of drink on physiological response during exercise and recovery phase. The subjects were male baseball players, and exercise protocol was performed with 45 minutes treadmill running and 85％ VO$_2$ max intensity. Brix, pH and titratable acidity of developed drink were 9.5％, 3.3 and 0.22％. The approximate nutritional composition of beverage was carbohydrate, 5.98％, total dietary fiber, 0.42％, crude protein, 0.70％, crude fat, 0.20％ and crude ash, 0.20％. Developed. traditional functional beverage contained K (4.00 mg％), Na (3.68mg％), Ca (2.54mg％), Mg (1.60mg％) and Fe (0.29mg％). Developed beverage drinking group showed a lowest heart rate during exercise and recovery phase than the other two group (water group and ion beverage group). In the change of blood lactate concentration, developed beverage intake group showed a significant lowest values during exercise and recovery phase. And blood hematocrit values and osmolarity were lowest in the developed beverage intake group. In these results, exercise performance capacity was expected to improve most highly with the developed drink from composition with medicinal plants. Also developed beverage was effective in recovery of exercise-induced fatigue. Thus developed drink with medicinal plants can be used as a functional material improving decrease fatigue effects in beverage industry.

A survey of mushrooms was conducted in Xishuangbanna, Yunnan Province, China, in the rainy season (May to October) of 2012, 2013, and 2014, during which 16 specimens of Termitomyces were collected. Preliminary macro- and micro-characteristics, together with ITS sequence data, showed that four of the specimens belonged to a new species (Termitomyces fragilis), while the other 12 belonged to T. aurantiacus, T. eurrhizus, T. globules, T. microcarpus, and T. bulborhizus. In this paper, T. fragilis is introduced as a species new to science based on morphological characterization and phylogenetic analyses. Macro- and micro- morphological descriptions, color photographs and line drawings of the new species, and a phylogenetic tree to show the placement of the new species are provided. T. fragilis is then compared with other closely related taxa in the genus Termitomyces.
