“…The main active ingredient of D. huoshanense is polysaccharide. Many studies have shown that the content of polysaccharide in the stem of D. candidum is higher than that in leaves and roots, indicating that the stem is the main synthesis and accumulation part of Dendrobium polysaccharide (Yan et al 2010). Previous research found that the polysaccharides of D. candidum mainly consisted of mannose and glucose, while the leaf polysaccharides were acidic heteropolysaccharides, including mannose, glucose, galactose and arabinose (Fan et al 2009).…”

Polysaccharide is the main active component of Dendrobium huoshanense, and it is also an important indicator to evaluate its quality. In this study, the polysaccharides and invertase components in the stems and leaves of D. huoshanense were studied to provide a theoretical basis for the full exploitation and utilization of its resources. Taking the D. huoshanense grown in the wild, indoors and outdoors as a test material and choosing stems and roots of D. huoshanense for 1 year, 2 years and 3 years of growth, the polysaccharide content of different samples was determined, and the relative expression activity of sucrose metabolism-related genes in different samples was detected by qRT-PCR. Western blot was used to detect the changes of sucrose metabolism-related proteins in different samples. The results showed that the content of polysaccharide in the wild D. huoshanense was the highest, the indoor growth was the second, the growth in the outdoor was the lowest, and the content of polysaccharide in the stem was significantly higher than that in the root. The expression of D. huoshanense neutral/alkaline invertase (DhNI), D. huoshanense sucrose synthase (DHSS) and D. huoshanense sucrose phosphate synthase (DHSPS) was the highest in wild D. huoshanense, followed by indoor growth, and the expression in stem was much higher than in root. Western blot results also indicated that DhNI, DHSS and DHSPS protein expression was highest in wild, followed by indoors. The stem is much higher than the root and is grown for 2 years in the same growing environment for more than 1 year and 3 years. The above results show that the nutritional value of D. huoshanense is related to the decomposition of sucrose and the accumulation of polysaccharides in plants. The experimental results provide a theoretical basis for better exploitation and utilization of D. huoshanense resources.

“…The content of bioactive compounds varies depending on species (Choonong et al., 2019; Klinsukhon et al., 2016; Sukatta et al., 2019), organ and development stage (Maksup & Obsuwan, 2020; Obsuwan et al., 2019), season (Jin et al., 2016), cultivation method (Xiao et al., 2015; Zuo et al., 2020), PGR use (Yuan et al., 2017), and production region (Hu et al., 2020; Lei et al., 2018). The bioactive compounds identified to date include polysaccharides (He et al., 2015; Liu et al., 2018; Obsuwan et al., 2019, 2020b; Zhong et al., 2022; Zhu et al., 2010), alkaloids (Liu et al., 2020a; Mou et al., 2021; Yang et al., 2014), antioxidants (Athipornchai & Jullapo, 2018; Klinsukhon et al., 2016; Li et al., 2020; Sukatta et al., 2019), flavonoids (Liu et al., 2020b; Wang et al., 2022; Zhao et al., 2021), amino acids (Hao et al., 2021; Zhao et al., 2021), bibenzyls (Liu et al., 2020a; Zhou et al., 2016), essential oils (Kang et al., 2011), and trace elements (He et al., 2015; Ni et al., 2018). These bioactive compounds manifest a diversity of medicinal properties associated with antiangiogenic, immunomodulating antidiabetic, cataractogenesis‐inhibiting, neuroprotective, hepatoprotective, anti‐inflammatory, antiplatelet aggregation, antifungal, antibacterial, antiherpetic, antimalarial, aquaporin‐5 stimulating, and hemagglutininating activities (Teixeirra da Silva & Ng, 2017).…”

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.
