  • Recently, there is a growing interest about unsaturated lecithin having excellent characteristics of skin affinity and absorbency. Accordingly, this study intended to develop a natural sulfuration material in order to enhance the stability of oxidation of unsaturated lecithin and substitute existing sulfuration materials which indicate variability and toxicity. As sulfuration components, plenol acid family, 3,5-dihydroxybenzoic acid, and flavanone were analyzed. Total polyphenol content was higher in the root extracts (133.85 mg/g) than in the fruit extracts (53.5 mg/g). Above 100 ppm polyphenol content, the free radical removal efficiency and lipid oxidation prevention of the root extracts were 20.1 and 19.2% superior compared with BHT respectively. Also, the extracts indicated high survival rate of more than 95% below 1250 ppm, showing the stability. For the stability of liposome made from an unsaturated lecithin, the root extracts were superior to the fruit extracts. Especially, 15.1 and 13.9% of sulfuration effect and zeta potential were improved with 9.3% reduced particle size compared with BHT as the control group, respectively.

  • Natural products derived from not only medicinal but edible plants have been used as sources of folk remedies and other useful materials, like as appetizers, health supplements and food additives. A short-term in vitro biomarker assay was accompilshed to assess cytotoxic activity on the human lung and ovary adeno cancer cell lines based on sulforhodamine B (SRB) method. As a result, the EtOAc soluble fractions from Trichosanthes kirilowii Max. and Dioscorea japonica Thunb. showed potent cytotoxicity as a below 30% of growth ratio of cancer cell at a concentration of 40 $\mu\textrm{g}$/ml on lung and ovary adeno cancer cell lines, and lung cancer cell line, respectively. Cytotoxic activity present in plant extracts appear to be promising candidates as functional foods among Korean wild edible plants, and further studies are warranted.

  • Adventitious shoot buds, without an intervening callus phase, were induced from stem explants of Trichosanthes kirilowii on MS medium supplemented with 2 mg/L BA. The culture medium, carbon source as well as plant growth regulators were found to influence further shoot multiplication and eventual shoot growth. A maximum number of shoots was obtained on a MS medium containing 0.5 mg/L BA and 3% sucrose. Shoot produced in vitro were rooted on half-strength phytagelled 1/2MS medium prior to transfer to green house condition.

  • The ami of our study was on the anti-obesity effect of ethanol extract from Trichosanthes kirilowii Maxim root (TKM) in murine adipocytes, 3T3-L1 cells. This study focused on anti-adipogenic activity through inhibition of cell differentiation in 3T3-L1 cells treated TKM. 100 ug/ml of non-cytotoxic TEM remarkablely inhibited content of triglycerol and suppressed expressions of $C/EBP{\alpha}$, $PPAR{\gamma}a$ and SREBP-1c related with lipogenic transcription factors in theres 3T3-L1 cells compared to (-)control cells. As phosphorylations of AMPK and ACC were incerased, HSL and CPT-1 mRNA expression increased upon TKM treatment, which involved in inhibition of fatty acid synthase expression. In conclusion, these results indicate that TKM can inhibit mRNA and protein expression of lipogenic genes in 3T3-L1 adipocytes. Our study suggests that TKM has potential anti-obesity effects and is a convergence therapeutic functional agent with anti-adipogenic activity via hypolipogenesis.

  • Physicochemical properties of Trichosanthes kirilowii Max. root and starch were investigated. Trichosanthes kirilowii root is made up of 69% of moisture, 2.7% of protein, 0.3% of crude fat, 2.0% ash and 3.4% of crude fiber. Starch granules were in the range of 4.1-22.0 microns in size, the average being 11.0 microns. The starch had raising power of 87.5, amylose content of 26.7% alkali number of 34.3 and blue value of 0.42. The initial and final gelatinization temperature were $60^{\circ}C$ and $67-68^{\circ}C$ respectively.

  • Although each part of Trichosanthes kirilowii is frequently used as medicinal herbs, study on the chemical composition is not sufficient. It was found that sarcocarp consists of 70% of carbohydrate, 13% of crude protein, 5% of crude fat, 6% of crude fiber and 6% of crude ash; seed consists of 62.59% of carbohydrate, 12.75% of crude protein, 14.80% of crude fat, 6.50% of crude fiber and 3.36% of crude ash; and root consists of 89.40% of carbohydrate, 4.10% of crude protein, 0.50% of crude fat, 3.50% of crude fiber and 2.50% of crude ash. Sarcocarp and seed contain fifteen kinds of amino acids such as Asp, Ser, Glu, Gly, His, Arg, Thr, Ala, Pro, Try, Cys, Met, Val, Leu, and Phe. Sarcocarp contain large quantities of phenylalanine and glycine and seed does not contain leucine but lysine. The mineral contents in Trichoxanthes kirilowii are 0.55% Ca, 0.91% Mg, 10.29% Na, and 0.17% K.

  • Transformed hairy roots were induced from in vitro grown plantlets of Trichosanthes kirilowii by infection with Agrobacterium rhizogenes strain ATCC15834. Transformed hairy roots exhibited active growth with high branching of roots on plant growth regulators-free medium. Cloned line (TR-03) of hairy root was tested for its growth and extracellular protein accumulation in medium under various culture conditions. Among the culture media tested, a full-strength MS medium had a pronounced effect on root biomass and extracelluar protein accumulation in medium. The maximum root biomass (2.4 g DRW/flask) and extracellular total protein contents $(28.3ug/m\ell)$ in medium was obtained at inoculum size of 2 g (FRW) and in MS medium supplemented with 4% sucrose. In addition, the optimal shaking speed for root growth and extracellular protein accumulation in medium were 100 rpm. The total extracellualr protein concentration reached a maximum of $28.3ug/m\ell$ at 4 weeks and decreased thereafter. Protein translation inhibitory activity was observed in culture broths and reached levels of 21.3 unit. These studies demonstrate that the transformed hairy roots can be utilized for the in vitro production of ribosome-inactivating proteins.

  • This study was conducted to determine the effects of seed storage temperature and pre-treatment on seed germination, seedling quality and vigor index of wild Trichosanthes kirilowii and Trichosanthes kirilowii var. japonica. As a result the highest germination rate of T. kirilowii was the 95% at seed stored in room temperature and then soaking for 24 hours in $dH_2O$. And the highest germination rate of T. kirilowii var. japonica was 96% at seed stored in $2^{\circ}C$ and then soaking for 24 hours in $GA_3$ (100 ppm). But the seed germination rate was non-significance in pre-treatment at seed stored in room temperature $2^{\circ}C$. Seedlings of T. kirilowii and T. kirilowii var. japonica showed not only the best seedling quality but also seedling vigor index in seed stored at $2^{\circ}C$ and then soaking for 24 hours in $GA_3$ (100 ppm). In this research, T. kirilowii and T. kirilowii var. japonica seed were stored in room temperature or $2^{\circ}C$, and then sown in peat moss, seed germination rate was more than 90% and production of superior quality seedlings.

  • A strongly cytotoxic fraction (Fc-2, ED50=0.0003$\mu\textrm{g}$/ml) against L1210 cell was obtained from the root, seed and fruit of Trichosanthes kirilowii. Administration of Fc-2 prolonged the life span of the BDF1 mice bearing L1210 and the ICR mice bearing S-180 by 135%, and 130%, respectively. The Fc-2 affected L1210 cells were enlarged in their diameters two or three times in comparison with the untreated ones. When 20mg/kg of Fc-2 was administered, intraperitoneally, all the mice were killed.
