A total of 33 extracts representing 26 plant species belonging to 24 families were collected from different regions of Bangladesh, and screened for their in vitro antibacterial activity against several pathogenic Gram-positive and Gram-negative bacterial strains using the conventional disc diffusion method. The most potent activity was exhibited by the extracts of Aegiceras corniculatum, Alocasia fornicata, Ceriops decandra, Cuscuta reflexa, Lasia spinosa, Lantana camara, Pandanus foetidus and Xylocarpus granatum. The extracts of Abtilon indicum, Derris trifoliata, Dendrophthoe falcat, Ruellia tuberosa and X. moluccensis did not show any antibacterial properties at test concentrations.

The extracts of some Bangladeshi medicinal plants, Possur (Xylocarpus mekongensis), Dhundul (Xylocarpus granatum), Gab (Diospyros peregrina), Kadom (Anthocephalus chinensis) and Sundari (Heritiera fomes), were assessed for their possible antinociceptive activity using acetic acid induced writhing model in mice. Most of these plants have been used in traditional medicine in Bangladesh as well as in other countries for the treatment of various ailments ranging from common cold to cancer. All these extracts significantly inhibited the acetic acid induced writhing in mice at the oral dose of 500 mg/kg body weight. The extract of Anthocephalus chinensis bark showed the most potent writhing inhibition (69.47%, P < 0.001) and that of Diospyros peregrina bark had the least (33.54%, P< 0.02).

Cacti of the genus Opuntia, which are widely distributed throughout Latin America, South Africa, the Mediterranean, and Korea, have been used not only as ornamental plants but also for their medicinal value. For example, Opuntia spp. have traditionally been used as hypoglycemic plants for treating diabetes mellitus. In this article, we review published papers dealing with the biological and medicinal properties of Opuntia spp.

The effects of crude extracts from medicinal plants on biological activity were investigated. The crude ethanol extract of H. paucistipula inhibited the growth of the Gram positive bacterium Bacillus subtilis ATCC 19659, (2 mm inhibition zone at 150 ${\mu}g$/disc) and the dermatophyte Trichophyton mentagrophytes ATCC 28185, (7 mm inhibition zone at 150 ${\mu}g$/disc), and toxic to P388 murine leukaemia cells ($IC_{50}\;2.48\;{\mu}g/ml$ at 75 ${\mu}g$/disk). This crude ethanol extract of H. paucistipula is the strongest antimicrobial and cytotoxic activities against P388 murine leukaemia cells (ATCC CCL 46 P388D1).

This study was performed to determine the cytotoxic effect of methanol extract from medicinal plants. The cell viability was determined by the MTT method. Their cytotoxic activities against three cancer cell lines such as A549, MDA-MB-231 and SNU-C4 cell line were tested. Among them, The methanol extract of Saururus Chinensis Bail showed the strongest cytotoxic effect against SNU-C4 cells. These results suggest that the methanol extract of Saururus Chinensis Bail possessed a potential antitumorous agent

This study was performed to determine antioxidative activity of solvent extracts from medicinal plant. As the result, methanol extract from Saurus chinensis Bail and Glycine soya exhibited superior free radical activity as well as reducing power. In particular, methanol extract from Saurus chinensis Bail showed high free radical activity with 130.08${\mu}g/mL$ as $IC_{50}$ value and strong reducing power at concentration of $400{\mu}g/mL$.

Phytoestrogens have been used as a food supplement to prevent osteoporosis. The isoflavones in the phytoestrogens are daidzein, genistein and formononetin which are present in various herbs. This study examined the quantity of isoflavones in medicinal herbs, which can be used as a phytoestrogen supplement; soybean. These isoflavones were quantified using high performance liquid chromatography (HPLC) with a UV/VIS detector. The concentration of daidzein in Puerariae Radix was $10,436.16{\pm}2,143.83\;mg/kg$ of the dried herb, which was much higher than that extracted from soybeans, $341.47{\pm}18.96\;mg/kg$. The amount of genistein in Sophorae flavescentis Radix ($336.09{\pm}50.89mg/kg$) was approximately 11 times higher than that extracted from soybean ($30.03{\pm}7.17mg/kg$). The level of formononetin in Dalbergiae odoriferae Lignum, $2,189.14{\pm}136.46mg/kg$, was the highest among the herbs tested. The total isoflavone content of Puerariae Radix was approximately 30 times higher than that extracted from soybean. Therefore, plants from the family Leguminosae, particularly Puerariae Radix, can be a good source of phytoestrogens.

안전한 천연물을 이용한 천연항산화제 개발 연구에 대한 관심이 고조되는 가운데, 지유, 진피, 천련자, 천문동, 청피, 편축, 하고초 7종의 천연 약용식물 추출물을 통해 항산화 활성을 측정하였다. 추출물의 총 페놀 함량은 지유가 열수추출물과 40% ethanol 추출물에서 각각 31.5 mg/g, 32.7 mg/g으로 가장 높게 나타났다. 추출물의 수용성 물질에 대한 항산화 효과는 DPPH radical 소거능이 지유, 진피, 천련자, 천문동, 청피, 편축, 하고초 7종의 천연 약용식물의 열수 추출물과 ethanol 추출물에서 80% 이상의 높은 소거활성을 나타내었다. ABTS radical cation decolorization을 측정한 결과, 7종의 천연 약용식물의 열수 추출물과 ethanol 추출물에서 85% 이상의 높은 저해율을 나타내어 매우 우수한 항산화 효과를 가지고 있음을 입증하였다. 지용성 물질에 대한 항산화 효과를 측정하기 위해 Antioxidant Protection Factor(PF)를 측정한 결과, 천련자 열수 추출물에서 1.65 PF로 대조구인 vitamin C 보다 높은 수준을 나타내어 지용성 물질에 대한 항산화 활성이 높음을 확인하였다. TBARs 생성 저해율을 측정한 결과 지유, 천련자, 청피, 편축, 하고초의 열수 추출물과 ethanol 추출물에서 99%에 가까운 높은 저해율을 나타내어 대조구인 vitamin C보다 지용성 물질에 대한 항산화 활성이 매우 높은 것으로 확인되었다.

본 연구는 비타민 E 및 한방부산물을 함유한 항생물질(T1), 비타민 E 및 한방부산물 함유 허브추출물(0.03%, T2) 그리고 비타민 E 함유 한방부산물 함유 효소제(0.1% aminolevulinic acid, T3)의 급여가 거세돈육의 일당증체량과 사료요구율등의 생산성 및 식육의 육질에 미치는 영향에 대해 연구하여 이들 처리 물질들의 항생제 대체물질로서의 가능성에 대해 연구하였다. 허브추출물 처리군(T2)의 일당증체량이 가장 좋은 결과를 나타내었으나, 일당증체량 및 사료요구율에 있어 대조구와 유의적인 차이를 나타내지 않았다. 혈청 총 콜레스테롤 및 LDL-콜레스테롤 함량의 경우 T2 처리군이 대조군보다 낮은 함량을 나타내었으며(각각 114.71과 68.09 mg/dL), 한약부산물과 비타민E의의 처리가 HDL-콜레스테롤을 높였으며, LDL-콜레스테롤을 낮추었다. 비타민을 첨가한 처리군 T1, T2 그리고 T3의 근육내 비타민의 함량이 대조군 보다 유의적으로 높게 나타났다(각각 2.11, 2.21 and 2.18 mg/kg). 잔류 항생물질의 경우 대조군에서는 chlortetracycline이 0.08 ppm이 검출되었으나 처리군에서는 검출되지 않았다. TBARS와 VBN 함량은 T2 처리군(각각 0.06 mg MA/kg과 11.21 mg%)과 T3 처리군(각각 0.05 mg MA/kg과 8.23 mg%)이 대조군보다 유의적으로 낮게 나타났다. 하지만 가열감량 및 드립감량은 대조군과 처리군과의 유의적인 차이가 나타나지 않았다.

In this study we examined the concerned literature for clinical use of Balsaminaceae plants focusing on the latest literature "zhong hua ben cao"(chinese materia medica, 1998). The findings were summarized as follows: 1. As an original plant, 27 species have been reviewed. 2. As a result of investigating oriental drug names by medicinal using part, a survey reported that the total of 22 species of oriental drug names, including 14 species of herba, 3 species of flos, 4 species of radix and rhizoma, and 1 species of semen, are being used for clinical use. 3. When we examined oriental drugs with five flavors by calculating and arranging their nature, effect, toxicity with points for conveniences sake, pungent and bitte showed 13 points, respectively, as main flavors. In drug nature, warm property of drug indicated 10 points and cold property of drug obtained 6 points. But as for other oriental drug, it is thought that we can recognize their significance. 4. With respect to efficacy, activating blood drug reached 10 kinds and wind- damp-dispelling 7 kinds, according to the examination. 5. In the examination on components and medicinal action, we examined that components are recorded in only impatiens balsamina's whole grass, flowers, root, root stems, and seeds, and Impatiens noli-tangere's whole grass. In medical action, we found out that the components are recorded in impatiens balsamina' flowers and seeds; impatiens noli-tangere's whole grass and flowers; and Impatiens textori' whole grass. 6. As a result of examining clinical prescription, the total of 84 kinds of clinical prescriptions by disease nature were examined, of which the prescription of Impatiens balsamina showed 19 cases in total, which was remarkable.
