  • 뽕나무의 화아의 기내배양을 실시할 경우 배지종류 및 생장조절물질의 농도가 각 기관의 생장 및 분화에 미치는 영향을 조사한 결과를 요약하면 다음과 같다. 1. Murashige and Skoog 배지는 Greshoff and Doy 및 Wolter and Skoog 배지에 비하여 자웅화아의 생장에 양호한 결과를 나타내었으며 자화의 성장은 2.0ppm BAP 농도에서 양호하였다. 2. 자화 및 웅화의 화아를 가지고 있는 삽수를 7일간 삽목하여 발아시킨 후 배양한 구가 삽목을 하지 않고 직접 치상한 구보다 화아의 발육이 양호하였다. 3. 고농도 Kinetin과 저농도 IAA를 혼용 첨가한 M.S. 배지에서 생장이 양호하여 발화되었고 건전한 주두 및 약을 얻을 수 있었다.

  • ${\gamma}$-Aminobutyric acid (GABA) content in fermented plant products and their main plant materials (aerial part of Acanthopanax sessiliflorus, fruit of Crataegus pinnatifida, and whole plant of Morus alba) was determined by high-performance liquid chromatography. GABA was quantified using a reverse-phase column with a gradient elution program (water:acetonitrile =90:10 to 0:100 for 40 min). UV detection was conducted at 280 nm. GABA content was measured in fermented plant products (15.07 mg/g), aerial part of A. sessiliflorus (4.49 mg/g), fruit of C. pinnatifida (10.59 mg/g), and whole plant of M. alba (2.31 mg/g). The presence of GABA in fermented plant products, including A. sessiliflorus, C. pinnatifida, and M. alba is important in industrial application for health supplements.

  • The in situ nylon bag degradation and in vitro intestinal digestibility of dry matter (DM), and crude protein (CP) of mulberry (Morus alba) plant fractions was studied at four harvest stages, 3 (W3), 5 (W5), 7 (W7) and 9 (W9) weeks. Degradability of DM and CP of the whole plant and stem fractions declined significantly (p<0.01) with advancing plant maturity in the order W3>W5 and W7>W9 and W3>W5>W7>W9, respectively. The degradation of DM and CP of the leaf fraction was also influenced by plant maturity but no trend was observed. The degradation of DM and CP of the whole plant and leaves increased rapidly during the first 48 and 24 h of incubation, respectively, when maximum degradation was reached. In vitro intestinal digestibility of CP was more influenced by the residence time in the rumen than by plant maturity. This study showed that mulberry is suitable as a supplement, particularly to low-quality roughages, in providing a source of rapidly available nitrogen to the rumen microbes, hence improving the roughage degradability and intake.

  • Inhibitory effects of 130 medicinal plants on hyaluronidase activity were analyzed. The medicinal plants are clinically used as herbal medicines for korean traditional prescriptions. Six out of the 130 herbal medicines exhibited more than 50% of inhibition on hyaluronidase activity by their total methanol extracts with 5mg/ml as a final concentration. The active total methanol extracts were prepared from cortex of Acantbopanax gracilistylus, lignum of Caesalpinia sappan, radix of Glycyrrhiza uralensis, radicis cortex of Morus alba, herba of Prunella vulgaris, and radix of Sanguisorba officinalis. These active total methanol extracts were sequentially fractionated with dichloromethane, ethyl acetate, n-butanol, and then water. Among the solvent-fractionated extracts, the butanol fractions of Acantbopanax gracilistylus and Glycyrrhiza uralensis with 1 mg/ml as the final concentration exhibited more than 50% of inhibition on hyaluronidase activity, and the other fractions with the same concentration did less than 20% of inhibition.
