300 Tahun Linnaeus: Pandanaceae, Linnaeus Dan Koneksi Swedia
Pandanaceae is one of the three large and important families within the Monocotyledoneaie consisting of approximately 900 species found only in the Old World Tropics. Malesia is the region of importance for the fanmyfwhere the prominent diversity and the three principal genera (Freycinetia, Pandanus, and Sararanga) are found.Pandanaceae is also an important family of the Monocotyledoneae in the Malayo-Austronesian and^elanesian cultures.The USAge of pannans in the Melanesian culture is more diverse and incorporating more number of species. Although pandan was first described by the two distinguish Dutch naturalists, Rumphius and Rheede tot Drakenstein, the introduction of pandan into the world of Botany was started and in the early stage also involved Swedish botanists, from Linnaeus to Fagerlind. Linnaeus still suggested Pandanus as a possibly member of Bromelliaceae. Linnaeus Jr. placed it as a genus of its own, Pandanus, thus laid the firm foundation for the classification of the genus and the entire family.The information on Pandanaceae encompassing morphology to history is described in this paper, including the significance of the family in relation with the Agenda 21
Kajian Etnotaksonomi Pandanus Conoideus Lamarck Untuk Menjembatani Pengetahuan Lokal Dan Ilmiah [Ethnotaxonomical Study on the Red Pandan (Pandanus Conoideus Lamarck) in Order to Correlate the Local Wisdom and Scientific Thought]
Red pandan (Pandanus conoideus Lamarck) is an important plant for the people of the Arfak Mountain in the Province of Papua Barat (West Papua), Indonesia that include the tribes of Meyah, Sougb and Hatam. In total there are 10 morphological variations found, each with a local (vernacular) name.The local nomenclature used by the three tribes is in correspondence with the formal botanical nomenclature, but not identical. The result of the ethnotaxonomical study shows that the basic name equals to species name, while attribute refers to infraspecific classification.Attribute is suggested to be addressed to the category of variety in the formal (botanical) taxonomy rather than to subspecies.Ethnotaxonomy is proven to be a good alternative solution for the problems faced in the formal taxonomy
Evaluasi Antibakteri Dan Antioksidan Ekstrak Smilax Spp. Dari Pulau Enggano [Evaluation of Antibacterial and Antioxidant of Smilax Spp. Extracts Collected From Enggano]
Three species of Smilax spp. (Smilax macrophylla, S. odoratissima and S. zeylanica) collected from Enggano island were evaluated for their potential as an antibacterial and antioxidant. Stems and leaves of three species of Smilax spp. were extracted successively with nhexane,chloroform, ethyl acetate and methanol. Antibacterial activity was evaluated by TLC-bioautography against Eschericha. coli InaCC B5 and Staphylococcus. aureus Ina-CC B4. The antioxidant activity was analyzed by DPPH free radical activity by bioautography method. The value of minimum inhibitory concentration (MIC) and IC50 of active extracts were done by serial dilution in 96- well microplate. The results showed that 20 extracts have antioxidant activity, 13 extracts inhibited the growth of S. aureus Ina-CC B4, and 14 extracts inhibited the growth of E. coli Ina-CC B5. MIC values of active extracts against S. aureus Ina-CC B4 were in the range of 128 - > 512 µg / ml, while the values of MIC against E. coli B5 Ina-CC were > 512 µg / ml. IC50 values of extracts that has antioxidant activity were in the range of 184.11-4549.34 mg/L
