“…Palmitic acid was the only compound shared by all the five taxa examined. This molecule is frequently found in the volatilome of several plant species (Orchidaceae included) [ 23 , 35 , 42 ], and also in other organisms; we observed that it was relatively abundant in D. chrysanthum (13%), followed by D. harveyanum (7.52%) and D. wardianum (5.76%), while in the remaining two species it was less represented.…”

“…High content of volatile esters has been linked with the strong flavor of the “snow chrysanthemum” cultivar of Coreopsis by Kim et al (2020) [ 44 ]. In D. moschatum , a putative role as semiochemicals involved in pollinator attraction has been hypothesized for methyl and ethyl esters by Robustelli della Cuna et al (2017) [ 23 ]. According to da Silva et al (1999) and Cseke et al (2007), terpenes are more abundant in flower VOCs of species pollinated by food-seeking bees [ 45 , 46 ].…”

“…Robustelli della Cuna et al (2017), instead, compared the essential oil of different portions of D. moschatum (Buch.-Ham.) Sw., including the inflorescence: They observed differences among the volatile compositions, and then hypothesized that compounds like ketones or long-chain methyl and ethyl esters play a role as pollinator attractants [ 23 ]. The few reports dedicated to reproductive biology have stated that there are various ways for which Dendrobium species attract pollinators: There are cases of shelter mimicry [ 24 , 25 , 26 , 27 , 28 ], nectar rewarding [ 18 ], chemical and visual attraction [ 29 ], rest and mating place offering, or generalized food deception strategies like a simulation of other co-flowering species occurring in the same habitat [ 30 ].…”

A detailed chemical composition of Dendrobium essential oil has been only reported for a few main species. This article is the first to evaluate the essential oil composition, obtained by steam distillation, of five Indian Dendrobium species: Dendrobium chrysotoxum Lindl., Dendrobium harveyanum Rchb.f., and Dendrobium wardianum R.Warner (section Dendrobium), Dendrobium amabile (Lour.) O’Brien, and Dendrobium chrysanthum Wall. ex Lindl. (section Densiflora). We investigate fresh flower essential oil obtained by steam distillation, by GC/FID and GC/MS. Several compounds are identified, with a peculiar distribution in the species: Saturated hydrocarbons (range 2.19–80.20%), organic acids (range 0.45–46.80%), esters (range 1.03–49.33%), and alcohols (range 0.12–22.81%). Organic acids are detected in higher concentrations in D. chrysantum, D. wardianum, and D. harveyanum (46.80%, 26.89%, and 7.84%, respectively). This class is represented by palmitic acid (13.52%, 5.76, and 7.52%) linoleic acid (D. wardianum 17.54%), and (Z)-11-hexadecenoic acid (D. chrysantum 29.22%). Esters are detected especially in species from section Dendrobium, with ethyl linolenate, methyl linoleate, ethyl oleate, and ethyl palmitate as the most abundant compounds. Alcohols are present in higher concentrations in D. chrysantum (2.4-di-tert-butylphenol, 22.81%), D. chrysotoxum (1-octanol, and 2-phenylethanol, 2.80% and 2.36%), and D. wardianum (2-phenylethanol, 4.65%). Coumarin (95.59%) is the dominant compound in D. amabile (section Densiflora) and detected in lower concentrations (range 0.19–0.54%) in other samples. These volatile compounds may represent a particular feature of these plant species, playing a critical role in interacting with pollinators.

“…The presence of hydrocarbons as allelochemicals is associated with epicuticular wax chemistry playing an important role in plant/herbivore interactions. Saturated alkanes exerted an interesting, although limited, activity in pollinator deception in different floral species [25,29,30,31].…”

“…A portion of the essential oil from each sample was placed onto a glass column (7 × 30 mm) of silica gel 60, 230–400 mesh (Merck, Milano, Italy), preconditioned with pentane [29]. The non-polar fraction was eluted with 2 mL of pentane and used for the determination of double bond position in alkenes by alkylthiolation according to reported method [50].…”

The volatile fractions from fresh inflorescences of naturally growing orchids Anacamptis coriophora (L.) R. M. Bateman, Pridgeon & M. W. Chase subsp. fragrans (Pollini), Anacamptis pyramidalis (L.) R. Ophrys holosericea (Burm.) Greuter and Serapias vomeracea (Burm. f.) B. were isolated by steam distillation and analyzed by GC/FID and GC/MS. Saturated hydrocarbons were quantified as the major constituents of the volatile fraction (47.87–81.57% of the total essential oil), of which long-chain monounsaturated hydrocarbons accounted from 9.20% to 32.04% of the total essential oil. Double bond position in linear alkenes was highlighted by dimethyl disulfide derivatization and MS fragmentation. Aldehydes (from 3.45 to 18.18% of the total essential oil), alcohols (from 0.19% to 13.48%), terpenes (from 0.98 to 2.50%) and acids (0.30 to 2.57%) were also detected. These volatiles compounds may represent a particular feature of these plant species, playing a critical role in the interaction with pollinators. DPPH assay evaluating the antioxidant activity of the essential oils was carried out, showing a dose-dependent antioxidant activity.

Dendrobium, one of the largest genera of tropical orchids, is grown commercially on a large scale with an important economic impact in several ASEAN countries.Dendrobium orchids can be grown in a wide range of climates, but flower production is best under tropical conditions. Due to being the most popular orchid for cut flower production, many hybrids of Dendrobium have been produced with colorful and attractive blooms. Cut flowers of Dendrobium are popular worldwide. In addition, many Dendrobium cultivars can be grown as flowering potted plants and for other purposes such as in medicinal applications and for use in decorative products. Postharvest physiology and technology are important in maintaining the quality of both cut flowers and potted plants from production sites to the marketplace. Plants of the Dendrobium genus also contain a wide diversity of bioactive compounds that can be developed into medicinal and cosmetic products. This review describes the botany, cultivation, postharvest physiology, handling and utilization of Dendrobium.
