Quantification and Varietal Variation of Fatty Acids in Mulberry Fruits
Journal of Sericultural and Entomological Science, volume 45, issue 2, 2003, Pages 75~79
Fatty acids analysis was carried out with mulberry seed. As a result, palmitic acid, stearic acid, oleic cid and linoleic acid were detected as a major fatty acid. Their rates of composition were 8.8
2.3 and 81.2
6.9(％), respectively. The unsaturated fatty acids such as oleic acid and linoleic acid were abundant in mulberry seed. Paticularly, five accessions including ‘Gukkwang’, ‘Jaelaenosang’, ‘Sangbansibmunja (Jeonnam) ’, ‘Neunggeum’ and ‘Suwonnosang’ were observed only with linoleic acid. Unsaturated fatty acids are known to have physiological effects decreasing the serum cholesterol. From the above result, we confirm that mulberry fruits have abundant unsaturated fatty acids and anthocyanin pigments, and they are of great value as functional food resources.
Quantification and Varietal Variation of Free Sugars in Mulberry Fruits
Journal of Sericultural and Entomological Science, volume 45, issue 2, 2003, Pages 80~84
The component and content of free sugar in mulberry fruits were evaluated. In all accessions, fructose and glucose were identified as the major free sugar. The ratio of two components appeared in the same level. But CV (coefficient of variation. ％) of fructose and glucose were 23.6％, 23.4％, respectively. It might suggest that varietal variation exists in sugar contents. The mean of total free sugars were 9.11
2.14％. Among the tested 49 accessions, ‘Geunanosang’ showed the highest total free sugars in 14.67％, whereas ‘Cheongsipyung’ showed the lowest total free sugars in 5.57％. Also fruity characteristics as well as total free sugars to select the desirable mulberry varieties for the production of fruit were researched and analyzed. From that results, four suitable varieties such as ‘Hwansipchosaeng’, ‘Junggojo’, ‘ Kaery-angchosaengsipmunja’, and ‘Geunanosang’ were selected.

Journal of Sericultural and Entomological Science, volume 45, issue 2, 2003, Pages 85~89
This study was carried out in order to investigate the sensory characteristics and nutritional analysis of sherbet ice-cream and ice-bar with mulberry fruits. In the sensory characteristics, sherbet ice-cream and ice-bar with 2％ mulberry fruit extracts were revealed to have highest level on overall quality, color, texture, taste, and flavor. Content of crude protein, crude fat and crude ash were observed in higher level in 3％ mulberry fruit extracts than others. In mineral analysis, Ca and K content were the highest in sherbet ice-cream and ice-bar with mulberry fruits. Also Mg, Na, Fe and Zn content were higher level in 3％ mulberry fruit extracts than others.
Identification of C3G(cyanidin-3-glucoside) from Mulberry Fruits and Quantification with Different Varieties
Journal of Sericultural and Entomological Science, volume 45, issue 2, 2003, Pages 90~95
This study was carried out to identify of C3G (cyanidin-3-glucoside) from mulberry fruits and quantify with different varieties. C3G of mulberry fruits was extracted with 1％ HCl-MeOH and purified with open column (5
90cm) which filled with Amberlite IRC-50 ion exchange resin. The
max ranges of the purified C3G on UV/vis spectrum were 516nm and 280nm. Also, molecular weight of C3G from mulberry fruits by LC-Mass was determined as 449. From above results, we concluded that anthocyanin pigment of mulberry fruits was C3G only. The cyanidin-3-glucoside (C3G) was separated and quantified by High Performance Liquid Chromatography (HPLC) system using a Nova-Pack C
18/ column. Mean content of the 35 tested accessions was 0.89％. Also fruity characteristics as well as C3G content to select the desirable mulberry varieties for the production of fruit were researched and analyzed. We selected three suitable varieties such as 'Susungppong', 'Kangsun', and 'Jeolgokchosaeng(Chungpuk)'
Development of Anti-diabetes Drink Using with Silkworm(Bombyx mori L.) Extract
Journal of Sericultural and Entomological Science, volume 45, issue 2, 2003, Pages 96~102
This study was designed to develope the functional anti-diabetes drink, Dia-D using silkworm (Bombyx mori L) extract Sprague-Dawley (SD) male rats (160
10g) were fed basic diet (control group), and experimental diets (SWE-l0, 30, 60 groups and Daonil-40, 80 groups) added silkworm extract 10, 30 and 60mg/day or diabetes drug prepared and marketed by Handok Pham. Co., Daonil 40 and 80 mg/day for 12 days. Blood glucose contents were significantly decreased 25-30％ in SWE-30 and SWE-60 groups, and about 35％ in Daonil 40 and Daonil 80 groups compared with control group. Triglyceride (TG) and lipid peroxide (LPO) contents were significantly inhibited 10-16％ and 8-13％, respectively, in SWE-30 and 60 groups, whereas these contents were 13-30％ and 15％, respectively, in Daonil-40 and 80 groups compared with control group. Hydroxyl radical (OH) contents were significantly inhibited 19-20％ in SWE-30 and 60 groups, and 7-12％ in Daonil-40 and 80 groups compared with control group. Superoxide dismutase (SOD) activities were significantly increased 11-14％ in SWE-30 and 60 groups, and 12-29％ in Daonil-40 and 80 groups compared with control group. In results of clinical test using normal subjects, blood glucose content tested in NIAST subjects as anti-diabetes drink, Dia-D willi 100mg/vial was significantly decreased 17.5％, and these content tested in PKNU subjects as anti-diabetes drink, Dia-D with 150mg/vial was significantly decreased 20.5％ compared with control group. These results suggest that administration of Dia-D as an anti-diabetes drink prepared with silkworm extract may playa very effective role in a decreasing of blood glucose in hyperglycemia patients
The Detection and Multiplicity of Entomopathogenic Nematodes Using Silkworms (Bombyx mori)
Journal of Sericultural and Entomological Science, volume 45, issue 2, 2003, Pages 103~107
Entomopathogenic nematodes were isolated through the investigation in soils collected from cultivated and non-cultivated fields using silkworms (Bombyx mori) and Galleria mellonella trap. The detectable rate of entomopathogenic nematodes of silkworms trap was higher than the G. mellonella trap. This study indicates the detection of entomopathogenic nematodes from soils that silkworms are sensitive superior to the G. mellonella to entomopathogenic nematodes. The steinernema, rhabditidae, and diplogatroidae strains successfully cultured on the silkworms host as well as on artificial media. Reproductivity in the living silkworm larva and pupa was 1.5 to 3.5
5/ nematodes per host However, G. mellonella could be multiplied less than 5
5/ nematodes. The dried pupa of the silkworm following mositurize was cultured 0.5 to 2
5/) nematodes per host. The culture methods of the steinernema, rhabditidae, and diplogatroidae strains, using silkworm powder, extracted chicken intestine, and food waste fertilizer could be applicative, but rate of reproduction was low.
Identification of Infectious Fungus in the Artificial Cultivation Rooms of Paecilomyces tenuipes
Journal of Sericultural and Entomological Science, volume 45, issue 2, 2003, Pages 108~111
A infectious fungus (J131) recently isolated from artificial cultivation farms of Paecilomyces tenuipes is known to cause a great yield loss and deterioration of products. In this study, its occurrence and characterization were made. The isolate (J131) was identified as Paecilomyces farinosus (Holm ex S. F. Gray) Brown ＆ Smith. Colonies of the isolate on PDA grew moderately fast, attaining a diameter of 19mm within 14 days at 24
. Vegetative hyphae are smooth-walled and hyaline. Conidiophores mainly arose from the submerged mycelium, usually measuring 1.3-1.5
wide and consisted of verticillate branches with whorls of 2 to 4 phialides. Phialides of 3.8-5.8
, with a swollen basal portion tapered into a distinct neck of about 0.6-0.8
wide. Conidia arisen from the phialides, were ellipsoidal to fusiform, smooth-walled, hyaline, 1.8-2.4
. .When silkworm larvae were injected with concentration of 1
of infectious fungus J131, infection rate was 41.3％ and synnemata formation rate was 23.6％. Black spots were appeared on the surface of silkworm larvae in 5-9 days after injection. The surface of larvae was covered with hyphae which were gradually turned into yellow from white color during the incubation period of 3-4 days. 1 to several 4-6mm long synnemata of yellow or orange color were formed on the surface. The matured synnemata were ramified from its end and produced much conidia of white color.
