  • Objective: This study aimed to investigate the effect of Salvia miltiorrhiza (S.m.) aerial parts as an alternative ingredient on growth performance, nutrient digestibility, and digestive enzymes in growing rabbits. Methods: Treatments included five tested diets: a control (basal diet), antibiotic (basal diet+enramycin at 5 mg/kg), and S.m. aerial parts powder added at 3.0%, 6.0%, and 9.0% of feed using 300 growing rabbits. Results: The diets with S.m. aerial parts addition at 9.0% decreased (p<0.05) feed/gain compared to the control, but there were no differences in feed intake and body weight gain. In contrast with the control, the addition of antibiotic increased (p<0.05) digestibility of dry matter, crude protein, energy, fiber, and ash. The herb addition did not cause differences in the digestibility of most nutrients compared to the antibiotic, but fiber digestibility of the herb at 6.0% and 9.0% was lower (p<0.05) than that of the antibiotic. Moreover, the antibiotic and the herb also similarly increased (p<0.05) the activities of duodenal α-amylase, maltase, lipase, and trypsin, compared to the control, and the herb at 6.0% and 9.0% showed a greater (p<0.05) activity of elastase than the dose 3.0%. Conclusion: The obtained data indicate that S.m. aerial parts can be a potential forage in rabbit's diet at 9.0% with a beneficial regulation on nutrition and digestion.

  • In this study, the effects of soil conditions on antioxidant activities of the aerial and underground parts of rosemary were assessed to determine the most effective soil conditions for cultivation. The antioxidant activity was the highest (51.58±2.93 ㎍/mL) when cultivated in the mixture of gardening soil and vermiculite using DPPH assay. The antioxidant activity of underground parts the highest (127.48±12.38 ㎍/mL) when cultivated in the mixture of soil, vermiculite, and perlite. ABTS assay showed that the antioxidant activity of aerial parts was 230.34±57.93 ㎍·mL-1 when cultivated in the mixture of gardening soil and vermiculite and that of underground parts was 320.98±16.04 ㎍·mL-1 when cultivated in the mixture of gardening soil, vermiculite, and perlite. The total phenolic content of aerial parts was the highest (155.25±2.96 mg GAE/g) when cultivated in the mixture of gardening soil. The total flavonoid content of aerial parts was the highest (67.32±5.27 mg QE/g) when cultivated in the mixture of gardening soil. Therefore, the mixture of gardening soil, vermiculite, and perlite is superior to gardening soil alone for cultivation of rosemary to increase its antioxidant activity as well as total phenolic and flavonoid content.

  • Three tetrastilbene compounds were isolated from the aerial parts of Carex dimorpholepis Steudel (Cyperaceae) through repeated column chromatography. Their chemical structures were elucidated as kobophenol A (1), cis-miyabenol A (2), and kobophenol B (3), respectively, by spectroscopic analysis. These compounds were isolated for the first time from this plant.

  • The aerial parts of Brassica juncea (Cruciferae) called by brown or oriental mustard have been widely used as a spice in food and also traditional folk medicine as stimulant, diuretic and expectorant agent. And Gatkimchi made of the aerial parts of this plant are very popular in Korea. The aerial parts of this plant was refluxed with MeOH and then fractionationed with $CH_2Cl_2$, EtOAc, n-BuOH and $H_2O$, successively. One higher alcohol compound and three flavonoids were isolated from the EtOAc fraction through silica gel and Sephadex LH-20 column chromatographies. Their structures were elucidated as n-hexacosanol(1), kaempferol(2), isorhamnetin $3-O-{\beta}-D-glucopyranoside(3)$ and isorhamnetin $3-O-(6'-O-acetyl)-{\beta}-D-glucopyranoside(4)$ by comparison of spectral data with those in references. And compounds 1 and 4 were firstly isolated from this plant.

  • 이상에서 살펴본 바와 같이 산마늘을 산지별로, 그리고 부위별로 총아미노산 및 유리아미노산의 함량을 비교하고, 휘발성 유황화합물과 사포닌의 함량을 서로 비교하였을 때 그 이용목적에 따라 산지별로, 부위별로 각각 품질평가는 달라질 수 있음을 나타내었다. 즉, 아미노산을 이용하기 위해서는 이 식물의 지하부를 이용하는 것이 지상부를 이용하는 것 보다 훨씬 좋을 것으로 평가되었고 산지별로는 울릉도산의 지하부가 가장 많이 함유된 것으로 나타났다. 그러나, 산지별로 유리아미노산이나 총아미노산의 양이 크게 차이를 나타내지 않았다. 아미노산 중에서도 arginine, glutamine 및 asparagine 등은 다른 아미노산종에 비하여 현저히 많은 양을 함유함을 밝혔다. 그리고, 유황화합물의 경우에는 내륙종인 오대산산이나 지리산산의 것이 해양적 지리조건의 울릉도산에 비하여 현저히 많은 양을 함유하였음을 밝혔다. 내륙종은 지상부에 이들 화합물을 많이 함유하였으나 울릉도산은 지하부가 더 많이 이들을 함유하였다. 마지막으로, 사포닌 성분의 경우에는 지하부가 지상부보다 훨씬 많은 양을 함유하였고 그 순서는 울릉도산, 지리산산, 오대산산이었다. 오대산산은 다른 두 산지의 것보다 현저히 적은 양을 함유하였다. 산마늘 MeOH 추출물의 n-BuOH 분획의 양은 사포닌의 함량을 잘 방영하지 못하였는데 이는 이 분획에 저자 등이 구명한 allivicin 등 flavonol 배당체 등의 함유량의 차이에 일부 기인할 것으로 추측된다.

  • In the course of screening Korean natural products for acetylcholinesterase (AChE) inhibitory activity, it was found that a methanolic extract of the aerial parts of Corydalis incisa (Papaveraceae) showed significant inhibitory effects on AChE. Corynoline isolated from this plant inhibited AChE activity in a dose-dependent manner, and the $IC_{50}$ value of corynoline was $30.6{\;}{\mu}M$. The AChE inhibitory activity of corynoline was reversible and noncompetitive.

  • Phytochemical investigation of the aerial parts of Lonicera etrusca resulted in the isolation of three iridoids including two aglycones, loganin aglycone (log-1) (1) and lonicerin (log-2) (2), and the known common glycoside loganin (4). The study also afforded a coumarin derivative, 7-hydroxycoumarin (3), and a flavonoid glycoside, luteolin-7-O-$\beta$-D-glucoside (5). The structures were determined utilizing physical, chemical and spectral methods.
