  • 경상북도 포항시 북부해수욕장 부근 일대에 분포하는 마이오세의 두호층에서 산출된 3개의 꼬투리 화석을 Albizia miokalkora Hu and Chaney로 동정하였다. 이 화석은 현재까지 한국, 중국, 일본의 제 3기 마이오세 식물군에서 유일하게 산출되고 있고, 난온대에서 아열대-열대 지역에 걸쳐 광범위하게 나타나지만 종의 다양성은 매우 낮았다고 생각된다. 화석 Albizia miokalkora Hu and Chaney는 난온대와 아열대-열대 기후와 같은 따뜻한 기후에 적응한 식물로 추정된다.

  • 경상북도 포항시 북부해수욕장 부근과 창포동 일대에 분포하는 마이오세의 두호층에서 Albizia miokalkora의 열매화석 두개가 채집되었다. 꼬투리는 편평하고 길며 7개의 종자가 들어있다. 꼬투리 화석은 비록 인상이기는 하지만 완전한 형태를 보여준다. 화석 Albizia는 동아시아에서 온난한 온대기후에서 번성한 식물로 판단된다. 이 화석의 산출은 우리나라 신제3기의 식물군에서 두 번째 기록이다.

  • Fossil legumes of Albizia miokalkora Hu et Chaney (Mimosoideae) were found in the Miocene Duho Formation of the Yeonil Group distributed along the coast of Yeonil Bay in the Pohang area. The legume is flat and long and has 5-7 rounded seeds. The legumes of Albizia miokalkora are rare in the Cenozoic floras of the world and only known to Middle Miocene of East Asia. The fossil Albizia may use one of the important taxa to construct the biogeographic history of East Asia. This discovery is the first record of Albizia from the Neogene strata of Korea.

  • 인도네시아산 주요 조림수종(Albizia, Gmelina, Mangium)과 유망수종(Durian, Gandaria, Jengkol, Kupa, Mangga, Nangka, Rambutan)의 밀도, 수축률, 종압축강도와 경도 등 물리적 및 역학적 특성을 조사하였다. 그 결과, Mangium, Gandaria와 Rambutan은 높은 밀도를, Albizia, Durian과 Jengkol은 낮은 밀도를 보였다. 공시재료 중 Mangium, Gandaria와 Mangga의 수축률은 다른 수종에 비해 작았으며, Albizia, Jengkol과 Rambutan의 수축률은 다른 수종에 비해 높았다. 이방도(T/R)는 Albizia, Kupa와 Mangga가 낮았고, Gmelina, Durian과 Jengkol이 다른 수종에 비해 높았다. Mangium과 Nangka는 종압축강도와 경도가 높았으며, Durian, Jengkol과 Mangga는 낮은 종압축강도를, Albizia와 Gmelina는 낮은 경도를 보였다. 10수종 중 Albizia, Durian, Jenkol, Mangga의 4수종을 제외한 6수종의 물리적 및 역학적 성질은 비교적 우수한 것으로 판단되었다. 본 실험의 결과는 인도네시아산 조림목의 효율적인 이용 및 장래 조림을 위한 유용한 기초자료로 활용될 수 있을 것이라 생각된다.

  • The nutritive value and the effect of tannins on the utilization of foliage from three commonly used legumes, Acacia nilotica, Albizia procera, and Sesbania acculeata, were determined. Three mature rumen-fistulated bullocks were used to study in sacco degradability and twelve adult sheep were randomly allocated on the basis of live weight to 4 groups of 3 in each to study the in vivo digestibility of the foliages. In all foliages, the contents of crude protein (17 to 24% of DM) were high. Fibre was especially high in Albizia (NDF 58.8% of DM vs. 21% in Sesbania and 15.4% in Acacia). Contents of both hydrolysable (4.4 to 0.05%) and condensed tannins (1.2 to 0.04%) varied from medium to low in the foliages. Acacia contained the highest level of total phenolics (20.1%), protein precipitable phenolics (13.2%) and had the highest capacity to precipitate protein (14.7%). Drying in shade reduced the tannin content in Acacia and Albizia by 48.6 and 69.3% respectively. The foliages ranked similarly for each of the different methods used to estimate tannin content and activity. Acacia and Sesbania foliage was highly degradable (85-87% potential degradability of DM in sacco), compared to Albizia (52%), indicating a minimal effect of tannins in Acacia and Sesbania. Yet, in vitro, the tannins in the Acacia inhibited microbial activity more than those in Albizia and Sesbania. Following the addition of polyethylene glycol to neutralise the tannins, gas production and microbial growth increased by 59% and 0.09 mg RNA equiv./dg microbial yield respectively in the Acacia, compared to 16-17% and 0.06 mg RNA equiv./dg microbial yield in the other foliages. There was a trend for low in vivo apparent digestibility of N in the Acacia (43.2%) and Albizia (44.2%) compared to the Sesbania (54.5%) supplemented groups. This was likely to be due to presence of tannins. Consistent with this was the low N retention (0.22 and 0.19 g N/g NI) in sheep supplemented with Acacia and Albizia compared to that for the Sesbania (0.32). Similarly, a trend for poor microbial N yield was observed in sheep fed these foliages. Across the foliages tested, an increase in tannin content was associated with a reduction in ruminal fermentation, N digestibility and N retention. For overall nutritive value, Sesbania proved to be the superior forage of the three tested.

  • Higher incidences of adverse reaction associated with the prolonged use of synthetic drugs has once again increased the faith of humans in the traditional systems of medicine and motivated them to return back towards the clinical proven remedies for the treatment. It is also true that number of modern medications used in the present scenario, were developed from various plants. In Unani System of medicine, numerous herbal drugs are mentioned for medicinal purpose. Siras (Albizia lebbeck (L.) Benth.) is one of them. It is found all over India. Almost all parts of this plant are used for the treatment of ailments such as migraine, conjunctivitis, diarrhea, jaundice, skin problems, asthma etc. Many chemical constituents have been isolated from Albizia lebbeck such as lebbekannin, echinocystic acid, flavonoids, Linoleic acid, saponins etc. This review highlights the medicinal properties and therapeutic uses of Albizia lebbeck and scientific studies conducted on the drug in human and animal models that will provide the further research direction.

  • 본 연구에서는 인도네시아 조림지에서 생장한 4수종의 효율적 활용방안을 마련하기 위해 콘칼로리미터법에 의해 연소특성을 조사하였다. 그 결과, 평균열방출량($HRR_{mean}$)은 비중에 비례하였으며, 총열방출량(THR) 및 연소시간(FT) 등열관련 계수도 같은 경향을 나타냈다. Albizia는 열방출 시간이 짧았고, Mindi는 4수종 중 점화시간(TTI)과 연소시간(FT)이 길어져 4수종 중 연소속도가 늦었고, 열방출 시간도 가장 길게 이어져 결국은 Mangium 수종과 비슷한 총열방출률을 나타내는 것을 확인할 수 있었다. Albizia는 공시수종 중 가장 높은 비소화면적 값을 나타내어 연기발생비율이 높았고, 반대로 Mindi는 가장 낮은 비소화면적 값을 나타내 연기발생비율이 낮았다. 초기 연기방출률은 Albizia가 높았으나 이후에는 Gmelina와 Mangium 의 연기방출률이 높아져 총연기발생량이 높게 나타났다. Gmelina는 불완전연소로 인해 연소기간 중 가장 많은 일산화탄소 연기를 생성하였고, $CO/CO_2$ 비율은 다른 수종에 비해 3배 이상 높았다.

  • Quarrying of rock for construction purposes is a significant industry in any economy but has its negative impact. This study examined the impact of quarry activities on surrounding vegetation in Ogun State. Geographic Information System approach was used to map the various quarry locations present in different Local Government Areas in Ogun State; of which eight sites were selected namely Isara, Idode, Iwaye, Ogbere, Ilagbe, Adelokun Baaki Ake and Igodo. Vegetation composition analyses were carried out on the eight sites using Haga Ultimeter and chlorophyll content analysis. Data were subjected to descriptive and inferential statistics using SAS package (9.4 version). Sixty quarries were identified with Odeda Local Government Area (38.3%) having the highest percentage of quarry. The vegetative compositions analyses showed that Albizia zygia had the highest frequency (7) among identified plants in the quarries. The chlorophyll content of Albizia zygia in the wet season (492.2 mg Chl/m2) was significantly higher than dry season (464.4 mg Chl/m2) in all locations. However, Baaki Ake (Albizia zygia) chlorophyll content was highest among other locations in both seasons. In conclusion Albizia zygia showed highest resistance to quarry activities, hence common among other plants identified around the quarries.

  • In the present study, acetone extract and sub-fractions of Albizia amara stem bark were evaluated for their free radical potential. The results showed that the crude extract and all the fractions exhibited antioxidant and free radical scavenging activities under different in vitro assays. Among the different fractions, the ethyl acetate fraction exhibited higher DPPH and ABTS radical scavenging activities than the standard quercetin. A. amara stem bark might be valuable source of natural antioxidants that could be used for medicinal and food applications.
