Alphitonia excelsa merupakan salah satu tanaman yang berpotensi sebagai antioksidan dan telah digunakan secara turun temurun di masyarakat terapi berbagai macam penyakit. Hal tersebut mendasari tujuan penelitian ini, yaitu menentukan aktivitas total flavonoid kulit batang A. excelsa. Metode gunakan dalam pengujian adalah peredaman terhadap radikal 2,2-difenil-1-pikrilhidrazil (DPPH), sed...

Sandflies were collected in the base of tree-trunks in the seasons of high and least rainfall in the Ducke Forest Reserve, near Manaus in the State of Amazonas. Lutzomyia umbratilis was the most abundant sandfly species. Caryocar villosum, Chrysophyllum amazonicum, Dinizia excelsa, Eschweilera atropetiolata and Parkia multijuga were the tree species on which most sandflies were collected and re...

We investigated acclimation responses of seedlings and saplings of the pioneer species Cecropia schreberiana Miq. and three non-pioneer species, Dacryodes excelsa Vahl, Prestoea acuminata (Willdenow) H.E. Moore var. montana (Graham) Henderson and Galeano, and Sloanea berteriana Choisy ex DC, following a hurricane disturbance in a lower montane wet forest in Puerto Rico. Measurements were made, ...

A new stilbene, 4-[(2"E)-7"-hydroxy-3",7"-dimethyloct-2"-enyl]-2',3,4',5-tetrahydroxy-trans-stilbene (1), and the known compound chlorophorin (2) were isolated from the heartwood of Chlorophora excelsa. Both 1 and 2 showed tyrosinase inhibitory activity with IC(50) values of 96 and 1.3 microM, respectively.

Abstract Juniperus excelsa s. str. (Greek juniper) in Crimea is a relic species on the limits of its range, and represents Mediterranean flora Sub-Mediterranean part peninsula. Its origin history this area remains unresolved. We aimed to analyze phylogeny potential demographic expansion juniper as well study morphological differentiation. analyzed plant material from 59 trees inhabiting eight p...

The genus Oniella Matsumura 1912 is reviewed and seven species from China are recognized, including a new species, O. shaanxiana sp. nov., a new synonym, O. flavomarginata, syn. nov. and a new combination, O. albula (Cai & Shen, 1998) n. comb. transferred from Sophonia. O. excelsa (Melichar) is removed from this genus. The seven species are described and illustrated in detail, and a key to all ...

The biodiversity hotspot of central Chile is home to a high proportion endemic species, but some these species are inconspicuous and not easily observed. During botanical exploration in the Los Queules National Reserve (Chile), population Asplenium trilobum Cav. was identified. plants were found growing on bark Myrceugenia parvifolia (DC.) Kausel tree small swamp next specimens Drimys winteri J...

BACKGROUND AND AIMS Juniperus excelsa is an important woody species in the high mountain ecosystems of the eastern Mediterranean Basin where it constitutes the only coniferous species found at the tree line. The genetic diversity within and among J. excelsa populations of the eastern Mediterranean Basin is studied in the light of their historical fragmentation. METHODOLOGY Nuclear microsatell...
