This study was performed to investigate the role of phytohormones in the bulbing of garlic in order to assess the yield and quality. The effect on endogenous plant hormones such as gibberellin (GA) content was also examined during growth stage i.e. clove differentiation to bulbing in garlic. More than 18 gibberellins in garlic were identified with extensive gas chromatograph-mass spectrometry-selected ion monitoring (GC-MS-SIM) quantitative analysis. The results showed that GAs were biosynthesized by both non C-13 hydroxylation pathway (NCH) and early C-13 hydroxylation pathway (ECH) in garlic plant. It was also revealed that NCH pathway leading to synthesis of bioactive $GA_4$ was the more prominent GA biosynthesis pathway than ECH pathway in which bioactive $GA_1$ was synthesized. Total GAs level was gradually increased from clove differentiation to bulbing and later decreased, which portrays the active role of GA in differentiation. The biosynthesis ratio of bioactive $GA_4$ and $GA_1$ concentration was similar to that of total GAs content, which was closely related with bulb development in garlic.

Sponge cakes were prepared by replacing wheat flour with rice flour ranging from 10-40% and their physico-chemical, textural and sensory properties were examined. Rice flour addition decreased the moisture content and increased the total sugar and protein contents of the sponge cake. The viscosity and specific volume of batter increased with rice flour addition. 'L' values of crumb of sponge cakes with 20% or more rice flour were lower, whereas corresponding 'a' values were higher than those of the control. Textural hardness was increased, and textural cohesiveness and springiness were decreased with the addition of 30% or 40% rice flour. perceived that sponge cake with 20% or more rice flour had a weaker sweet flavor than the others. With the addition of 30% or 40% rice flour, sponge cake showed a stronger roasted and weaker greasy flavor, and less softness and cohesiveness than the other sponge cakes. The sensory did not find my significant difference in overall acceptability between the control and rice flour-added sponge cakes. Therefore, wheat flour could be replaced by rice flour up to 40% without reducing acceptability.

The nutritional composition of thawed Hanwoo beef fed no mugwort (T0) and thawed Hanwoo beef fed mugwort (T1) were analyzed after freezing at $-20^{\circ}C$ for 12 months. Also the effect of feeding mugwort was investigated by comparing physicochemical and palatability changes by chilling the beef after thawing. There were no significant differences in general components of T0 and T1 Hanwoo beef. Among the minerals, there were no significant differences in the contents of Ca, P, K, Mg and Zn, however Na content in T0 and Fe content in T1 were significantly higher. The total amino acid did not show a significant difference but leucine was found to be higher in T0 than T1, and glycine, cysteine, histidine and arginine were higher in T1 than T0. Regarding fatty acids, stearic acid was higher in T0, while palmitoleic acid, oleic acid and total unsaturated fatty acid was significantly higher in T1. The hardness value became lower by chilling after thawing regardless mugwort consumption, and therefore the tenderness improved. The freshness, fat rancidity and antioxidant activity of thawed Hanwoo beef changed more slowly for T1 than T0, which indicates that feeding mugwort had a positive effect. There were no significant differences in taste, juiciness, tenderness or and palatability of the cooked beef between T0 and T1 for both 0 days and 3 days after thawing. However, the aroma of cooked T1 beef was significantly superior.

Cultivated wild ginseng is a widely used dietary supplement and medicinal herb. The aim of this study was to optimize the ginseng using high performance liquid chromatography (HPLC)- charged aerosol detection (CAD) for ginsenoside analysis. CAD measures the physical property of an analyte and responds to almost all non-volatile species, independent of their nature, spectral properties, or particle size. It has become widely employed in pharmaceutical analysis. The cultivated wild ginseng extracts were analyzed for compositions of ginsenosides Rb1, Rd, Rg1, Rf, Re, and Rh1. The optimal analysis condition was set up from an experiment using a gradient. Ten grams of cultivated wild ginseng were extracted with 95% EtOH 100 ml for 24 hr at 80℃. The contents of the 6six major ginsenosides in the cultivated wild ginseng extract were Rb1 (5.48±0.12 mg/g), Rd (5.33±0.14 mg/g), Rg1 (12.80± 0.05 mg/g), Rf (19.08±0.68 mg/g), Re (19.87±0.05 mg/g), and Rh1 (16.47±0.16 mg/g), respectively. HPLC showed that the protopanaxatriol group (Rg1, Rf, Re, Rh1) had more content than the protopanaxadiol group (Rb1, Rd) in cultivated wild ginseng extract. In summary, the ginsenosides were identified with HPLC-CAD analysis, and their presence and quantity imply the importance of quality control, as well as the pharmacological activity of the ginseng root.
