“…In terms of microscopic identification, Dendrobium officinale could be identified by vascular bundle sheath observed under the fluorescence microscopy and the distribution of raphides under normal light microscopy [95]. In addition, the taxonomy, phylogeny, and breeding of Dendrobium species have made great progress as the advance of molecular markers in the past two decades [96]. …”

Ethnopharmacological Relevance. Dendrobii Officinalis Caulis, the stems of Dendrobium officinale Kimura et Migo, as a tonic herb in Chinese materia medica and health food in folk, has been utilized for the treatment of yin-deficiency diseases for decades. Methods. Information for analysis of Dendrobium officinale Kimura et Migo was obtained from libraries and Internet scientific databases such as PubMed, Web of Science, Google Scholar, ScienceDirect, Wiley InterScience, Ingenta, Embase, CNKI, and PubChem. Results. Over the past decades, about 190 compounds have been isolated from Dendrobium officinale Kimura et Migo. Its wide modern pharmacological actions in hepatoprotective effect, anticancer effect, hypoglycemic effect, antifatigue effect, gastric ulcer protective effect, and so on were reported. This may mainly attribute to the major and bioactive components: polysaccharides. However, other small molecule components require further study. Conclusions. Due to the lack of systematic data of Dendrobium officinale, it is important to explore its ingredient-function relationships with modern pharmacology. Recently, studies on the chemical constituents of Dendrobium officinale concentrated in crude polysaccharides and its structure-activity relationships remain scant. Further research is required to determine the Dendrobium officinale toxicological action and pharmacological mechanisms of other pure ingredients and crude extracts. In addition, investigation is needed for better quality control and novel drug or product development.

“…[6] Dendrobium has been a traditional health-promoting medicine and food source for many decades in Asia. [7] Based on diverse reports, many functional substances have been found in D. officinale, a high proportion being polysaccharides with positive bioactivities, such as antioxidant activities, immunoregulation, and the treatment of Sjogren's syndrome; while demanding cultivation contributes to a fairly high price in the current market. [8,9] In a previous study, high levels (yield 38.15% ± 0.20) of a novel polysaccharide (named as DAP) in D. aphyllum; and DAP structure was very similar to that of D. officinale polysaccharide (DOP).…”

Plant polysaccharides exert a wide range of biological effects on the intestinal function. In this study, four polysaccharides containing β-D-Glup, including Dendrobium officinale polysaccharide (DOP), Dendrobium aphyllum polysaccharide (DAP), and glucans from yeast (G-Y) and barley (G-B), were investigated in vitro for their intestinal-promoting functions such as inhibition of digestive enzymes, effect of blood glucose and blood lipid levels by using ultraviolet spectrophotometry, as well as the relationship of their structures to those functions. The results indicated that all polysaccharides significantly slowed glucose diffusion rate, decreased protease, and pancreatic lipase activities. Increased branching degrees had a deleterious effect on the α-amylase activity but increased bile acid binding. Increased calcium concentration in glucans (G-Y and G-B) and increased mannose molar ratio in Dendrobium polysaccharides (DOP and DAP) were correlated with increased pancreatic lipase inhibition. The polysaccharides with higher glucose content and branching degrees had higher bile acid binding and disruption of cholesterol micelle formation. These polysaccharides exerted a variety of potential health-promoting effects attributed to their different structures, which should be further investigated in vivo.

“…Current efforts regarding D. officinale breeding include germplasm collection, identification, evaluation, and conventional hybridization. Breeding objectives are largely focused on improving morphological characteristics and biomass production (Teixeira da Silva et al, 2016). Only a limited number of cultivars have been released thus far .…”

Dendrobium officinale Kimura et Migo is a famous traditional Chinese medicinal plant. It produces various phytochemicals, particularly polysaccharides, which have nutraceutical and pharmaceutical values. To increase its biomass production and polysaccharide content, our breeding program has generated a series of polyploid cultivars through colchicine treatment of protocorm-like bodies (PLBs). The present study compared two tetraploid cultivars, 201-1-T1 and 201-1-T2, with their diploid parental cultivar, 201-1, in an established in vitro culture system. Tetraploid ‘201-1-T1’ and ‘201-1-T2’ had shorter leaves and shorter and thicker stems and roots, and they produced higher biomass compared with the diploid cultivar. The length and width of stomata significantly increased, but stomatal density decreased in tetraploid cultivars. The PLB induction rates from the stem node explants of the tetraploid cultivars were significantly higher than those of diploid. However, the PLB proliferation of tetraploids was lower than that of the diploid. The mean number of plantlets regenerated from tetraploid PLBs was also lower than that of the diploid after 4 months of culture. Polysaccharide contents in stems, leaves, and roots of 6-month-old tetraploid plantlets were significantly higher than those of diploids. The polysaccharide content in the stem of ‘201-1-T1’ was 12.70%, which was a 2-fold increase compared with the diploid cultivar. Our results showed that chromosome doubling could be a viable way of improving D. officinale in biomass and polysaccharide production.
