“…Species of the genus Rhododendron occur throughout the Northern Hemisphere and the Southern Hemisphere in South Eastern Asia and Northern Australasia. The plant is originally present in mountainous areas characterized by acidic well-drained soil, regular rainfall and cool summer temperatures [ 7 ]. On the other hand, majority of the genus prefers cooler temperature including the subgenus Hymenanthes .…”

Background Rhododendron species have been traditionally used in countries like China, Nepal, Russia and North America for treating human diseases. These species are known to be a good source of polyphenolic plant secondary plant metabolites. They are known to have beneficial health properties for humans and have been used to treat diseases like asthma, skin diseases. In this contribution we investigate the phenolic profile and antibacterial activity of extracts from several plant organs including for the first time from leaves of different development stages.MethodsIn this study, the polyphenolic profile of fruits, flowers and leaves of different ages of Rhododendron ambiguum and Rhododendron cinnabarinum were studied by using HPLC–MS and compounds identified based on high resolution masses and identity of tandem mass spectra, UV/VIS spectra and retention times if compared to standards.ResultsFifty-nine different polyphenols including isomers were identified in these species by their fragmentation pattern and high resolution data. Also, the antibacterial activity of these parts (leaves, fruits and flowers) against gram-positive bacteria was studied.ConclusionThe leaves and fruits contained more polyphenols than the flowers. With the exception of flowers, the fruits and leaves of both species were also determined to have a significant antibacterial effect against four gram-positive bacteria.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-017-2601-1) contains supplementary material, which is available to authorized users.

“…Also, searches for stream heads on topographic maps allowed for new populations to be discovered. May-whites are found more commonly on mature hardwood slopes above streams (Horn 2005). This resurvey showed that the species are also more commonly found in a Mesic Mixed Hardwood Forest.…”

“…Rhododendron eastmanii Kron and Creel (hereafter May-white) was first described from two populations in South Carolina (Kron and Creel 1999). Since then, personal research has resulted in the discovery of numerous populations in 13 counties of South Carolina, mostly in the Broad and Congaree River watersheds (Horn 2005(Horn , 2019. Counties with the largest number of populations include Calhoun, Laurens, Newberry, and Union.…”

Rhododendron eastmanii is a species endemic to South Carolina and common in the Enoree Ranger District of the Sumter National Forest. A four-year study was undertaken to revisit known populations and to locate new populations. A total of 2,035 individuals in 38 populations were documented, including 663 seedlings, 705 non-flowering adults, and 667 flowering individuals. Plants were most commonly found on mature hardwood slopes above headwater streams. Pollinator visitors included eastern tiger swallowtail (Papilio glaucus), pipevine swallowtail (Battus philenor), and bumblebees (Bombus spp.). Concerns for the future of the species were noted due to deer browsing and subcanopy shading, especially from Acer leucoderme (a native tree) and Elaeagnus umbellata (an introduced shrub). This survey results in a better understanding of the species distribution and documents its demographic changes over time.
