  • In result of chemical properties of bamboo shoots and changes of chemical components of salted bamboo shoots during 120 days salting, the contents of moisture crude fat tannin and ascorbic acid were decreased but those of crude protein curde ash and salt concentration were increased. The main free amino acids of bamboo shoots were serine arginine alanine leucine and tyrosine. The content of total free amino acid was rapidly decreased in 80days-past of salting and after that slowly decresed. Wang bamboo shoots was the highest as 1060.18mg/100g in content of total free amino acid. The main mineral elements were K, P, Na and Mg. The contents of Fe and K were the hihest among them. The contents of P, Fe, Zn. Mn. Ge and Cu were decreased but K, Mg, Na and Ca were increased during salting. When fresh bamboo shoots were compared with salted bamboo shoots fresh bamboo shoots contained the contents of moisture crude protein crude fat tannin and ascorbic acid more than salted bamboo shoots did but the less the contents of ash fiber and salt concentration.

  • Dendrobium candidum is one of the well-known orchid on traditional and rare medicinal herb in China. We artificially cultured protocorm-like body and multiple shoots using the bioreactor culture system from Dendrobium candidum and experimented an efficacy as a cosmetic ingredient for skin care. Several studies previously have reported anti-tumor, wound healing and immunological function of Dendrobium candidum but other efficacies were not well known. In the present study, we investigated the cosmetic efficacy to know applicable value of protocorm-like body and multiple shoots cultured from Dendrobium candidum as a cosmetic ingredient. The biological activities of extracts from protocorm-like body, multiple shoots, aerial part and underground part of Dendrobium candidum were investigated. Results were found that extracts of protocorm-like body are superior to other extracts (underground part, aerial part and multiple shoots extracts) on anti-oxidant effect. Also, protocorm-like body extract contained the phenolic and flavonoid compounds more than aerial part, underground part and multiple shoots extracts. In addition, we investigated skin whitening effect related to whitening of skin. In tyrosinase activity and melanin synthesis assay, multiple shoots extract is superior to other extracts (aerial part, underground part and protocorm-like body), on inhibitory effect of tyrosinase activity and melanin synthesis respectively. These results indicate that the protocorm-like body and multiple shoots extracts cultured from Dendrobium candidum presents a new possibility of being applicable to skin improvement as a cosmetic ingredient.

  • To enhance the utilization of garlic shoots as food material, the nutritional and volatile flavor com pounds were investigated for garlic shoots, both cold and warm region type garlic shoots. Proximate composition of cold and warm region type was as follows, respectively; crude protein 2%, crude lipid 0.4%, crude ash 1.1% and 1.5%, crude fiber 1.3% and 1.5%. The major fatty acids of 2 varieties of garlic shoots were linoleic, palmitic and linolenic acid, and their desaturation ratio of them was comparatively high, showing 73.7 and 66.8%, respectively. Free sugars were composed of glucose, sucrose, fructose, arabinose and sorbitol. In the total amino acid analysis, the major amino acids were glutamic acid and aspartic acid. The volatile flavor compounds of fresh garlic shoots extracted by hexane and Likens-Nikerson steam distillation apparatus were identified to be methyl-2-propenyl disulfide, diallyl disufide, propenyl propyl disulfide, di-2-propyl-trisulfide, 2-vinyl-1,3-dithiane, and 2-vinyl-4H-1,3-dithiin. Hexane was more effective than steam distillation for extraction of volatile components of garlic shoots.

  • This study was conducted to refine a micropropagation method of water hyacinth (Eichhornia crassipes) in vitro. When young shoots were cultured on media with various concentrations of BA or TDZ alone, LS medium containing $5.0\;mgl^{-1}$ BA was found favorable for shoot proliferation from young shoots with a mean of 4.2 shoots. Using BA together with IAA, more shoots were obtained on LS medium containing $5.0\;mgl^{-1}$ BA and $1.0\;mgl^{-1}$ IAA with a mean of 5.7 shoots. In liquid medium, number of shoots and fresh weight per explant increased significantly. The best shoot proliferation and increasing of fresh weight were achieved on LS liquid medium containing $5.0\;mgl^{-1}$ BA and $1.0\;mgl^{-1}$ IAA with 6.9 shoots and more than 4,000 mg fresh weight. Of the different concentrations of LS salt, double strength of LS medium provided the highest shoot proliferation with 7.3 shoots, and fresh weight with 5,539 mg per explant. Shoot proliferation on LS medium containing $50\;gl^{-1}$ sucrose had better results with 8.7 shoots and 5,979 mg per explant in fresh weight than other conditions. In conclusion, the optimal level for shoot proliferation and biomass increase of water hyacinth was attained with the application of the double strength of LS medium containing $5.0\;mgl^{-1}$ BA, $1.0\;mgl^{-1}$ IAA and $50\;gl^{-1}$ sucrose.

  • These studies were conducted to investigate effects of phytohormone and activated carbon on the growth and rooting of teratoma shoots induced from Nicotiana tabacum cv. NC2326 transformed by Aerobacterium tumefaciens C58. GA was effective for shoot elongation and reduction of multiple shoots from teratoma shoot, however, leaves of teratoma shoot cultured on the medium with GA were pointed. ABA was also effective in promoting shoot elongation, but was not for reduction of multiple shoots. Teratoma shoot cultured on the medium with 1 n activated carbon promoted shoot elongation and inhibited the number of shoots differentiated, but was grown as abnormal shoot. Addition of 1% activated carbon and 0.5mg/l BA to culture media was effective for shoot elongation and reduction of multiple shoot and for formation of round leaves as normal leaves. Though these shoots were inoculated on the rooting medium, they could not from roots but formed multiple shoots. Boric acid, myo-inositol and sucrose were also ineffective on the rooting of teratoma shoots.

  • This study evaluated the composition two popular species of edible bamboo shoots in Korea (Phyllostachyspubescens and Sinoarundinarianigra) and the effect of their abundant dietary fiber on intestinal microorganisms in healthy young women. The ranges of total moisture, crude protein, crude lipid, crude ash, and dietary fiber content were 87.190.8, 2.943.5, 0.150.39, 0.411.05, and 4.206.15% (wet weight basis), respectively. Moisture and crude ash content increased after heat treatment; however, crude protein, crude lipid, and dietary fiber content were reduced after heating. The major minerals found in bamboo shoots were potassium, phosphorous, sulfur, magnesium, and calcium. In addition, glucose and fructose were abundant free sugars, while asparagine and tyrosine were the most abundant free amino acids. Approximately 70% of the total free fatty acids found in bamboo shoots were linoleic acid and linolenic acid. The ascorbic acid content was 6.60~17.56 mg/100 g (wet weight basis), and one phenolic compound, p-hydroxy benzoic acid, was 0.10.2% (wet weight basis) and detected by HPLC analysis. The intake of bamboo shoots for seven days significantly increased viable cell counts of Lactobacillus spp. and reduced viable cell counts of Bacteriodes spp. in feces (p<0.05). In our data, bamboo shoots may be useful in the food industry as high dietary fiber ingredients.

  • After topping, axillary buds of haploid plants derived from cultured anthers were treated with 0.4% aqueous solution of colchicine. Due to the high temperature and dry air at the time of treatment, most of the buds perished. A few months after the colchicine application, however, several shoots arose from the places where the dead buds were originally located. These shoots were mostly diploid. Induction of adventive shoots from the colchicine-treatedaxils was supposed to be rather effective method of obtaining diploid shoots from haploid plants. The diploid plants had larger floral organs than the haploid plants, and had good pollen fertility and seed setting. 24 bivalent chromosomes were observed at MI of the PMC's.
