Complete Chloroplast Genome Sequence of Dendrobium nobile from Northeastern India

The orchid species Dendrobium nobile belonging to the family Orchidaceae and genus Dendrobium (a vast genus that encompasses nearly 1,200 species) has an herbal medicinal history of about 2000 years in east and south Asian countries. Here, we report the complete chloroplast genome sequence of D. nobile from northeastern India for the first time.

Copacamphane, picrotoxane and cyclocopacamphane sesquiterpenes from Dendrobium nobile.

Dendronobilins K - N, four new sesquiterpenes with copacamphane-type (1), picrotoxane-type (2, 3) and cyclocopacamphane-type (4) skeletons, were isolated from the n-BuOH soluble fraction of the 60% ethanol extract of the stems of Dendrobium nobile. Their structures were established as 2beta,11,12-trihydroxycopacamphan-15-one (1), (2beta,3beta,4beta,5beta)-2,4,11,12-tetrahydroxypicrotoxan-3(15)-...

Isolation and characterization of novel EST-SSRs in the showy dendrobium, Dendrobium nobile (Orchidaceae).

Expressed sequence tag (EST)-derived simple sequence repeat (SSR) markers could enrich the current resource of molecular markers. In this study, microsatellite markers were developed for Dendrobium nobile Lindl. by mining the ESTs. Twenty-eight EST-SSRs amplified 2 to 6 nucleotide repeats with a mean number of 2.82 alleles per locus. The observed and expected heterozygosities per locus ranged f...

Interaction between a dark septate endophytic isolate from Dendrobium sp. and roots of D. nobile seedlings.

Interactions between an isolate of dark septate endophytes (DSE) and roots of Dendrobium nobile Lindl. seedlings are reported in this paper. The isolate was obtained from orchid mycorrhizas on Dendrobium sp. in subtropical forest. The fungus formed typical orchid mycorrhiza in aseptic co-culture with D. nobile seedlings on modified Murashige-Skoog (MMS) medium. Anatomic observations of the infe...

New benzodioxole compounds from the root extract of Astrodaucus persicus

There are many efforts for identification of natural compounds from dietary or medicinal plants. Young roots and aerial parts of A. persicus have been used as food additive or salad vegetable in some parts of Iran. In this study, different fractions of the root extract of A. persicus were subjected for isolation and purification of secondary metabolites. The methanol extract of the roots was fr...
