متن کاملSteroidal saponins from the roots of Dracaena marginata tam
A phytochemical investigation on the roots of Dracaena marginata yielded nine steroidal saponins. Six of the saponins were isolated as three pairs of 22-hydroxy furostanol saponins and their 22-methoxy derivatives including two new minors identified as 26-O-β-D-glucopyranosyl-22α-hydroxy-(25R)-furost-5en-3β, 26diol -3O-αLrhamnopyranosyl-(1→3)-[α-L-rhamnopyranosyl -(1→4)]–β–D -glucopyranoside an...
متن کاملAntihypoxic Activities of Aerial Parts and Roots of Ferula persica in Mice
Background and purpose: Hypoxia occurs in ischemia and heart attack, and leads to death. It involves production of reactive oxygen species. Antioxidants exhibit antihypoxic properties. Ferula persica has distinctive antioxidant activities. Nothing is known about the protective effect of this plant against hypoxia-induced lethality in mice. Materials and methods: Protective effects of methanol...
متن کاملTertiary Origin and Pleistocene Diversification of Dragon Blood Tree (Dracaena cambodiana-Asparagaceae) Populations in the Asian Tropical Forests
BACKGROUND The origin of extraordinarily rich biodiversity in tropical forests is often attributed to evolution under stable climatic conditions over a long period or to climatic fluctuations during the recent Quaternary period. Here, we test these two hypotheses using Dracaena cambodiana, a plant species distributed in paleotropical forests. METHODS WE ANALYZED NUCLEOTIDE SEQUENCE DATA OF TW...
متن کاملGrowth dynamics of endemic Dracaena cinnabari
Dragon ́s blood tree, a flagship endemic species of Socotra, is threatened with extinction 23 due to lack of natural regeneration, likely because of goat herbivory and/or climatic factors. Loss of 24 dragon ́s blood tree would result in loss of other native flora, heightening the importance of 25 formulating a conservation strategy for it. Although artificial afforestation might be used to offset...
