“…The second set of isolated compounds consisted of phenolic adducts (4-hydroxybenzyl) coupled to a 9,10-dihydrophenanthrene or phenanthrene derivative. This type of 4-hydroxybenzyl adduct (gastrodigenin) is very common in orchids and mostly found in the genus Arundina [67,68], Bletilla [69][70][71][72] and Pleione [40,73,74]. The third set of isolated compounds was a combination of a 9,10-dihydrophenanthrene and a phenylpropane derivative (trans-feruloyltyramine for 6, synapyl alcohol for 7 and 8).…”

Abstract:We report the first phytochemical study of the neotropical orchid Cyrtopodium paniculatum. Eight new compounds, including one phenanthrene 1, one 9,10-dihydro-phenanthrene 2, one hydroxybenzylphenanthrene 3, two biphenanthrenes 4-5, and three 9,10 dihydrophenanthrofurans 6-8, together with 28 known phenolic compounds, mostly stilbenoids, were isolated from the CH 2 Cl 2 extract of its leaves and pseudobulbs. The structures of the new compounds were established on the basis of extensive spectroscopic methods.

“…It is commonly found in Asian countries such as China, India, Nepal, Burma, Bhutan, Thailand, Laos and Vietnam, it is widely used as folk medicine to treat tuberculosis, chronic inflammation and fracture. 63,64 Lin et al, 74 have discovered three new Dihydrostilbenes from the whole plant of B. odoratissimum which was having a significant cytotoxicity toward human cancer cell lines. A new compound known as Bulbophyllinoside was discovered in the whole plant investigation of B. odoratissimum.…”

Orchidaceae family includes some of the most important ornamental plants with medicinal purposes. It is one of the largest groups among the Angiosperms. Even though there are several studies on the medicinal purposes of orchidaceae, lesser is known about the phytochemical compound present in the different parts of the plant. Therefore, in this present review paper five genus from Orchidaceae family has been selected to highlight the important phytochemical compounds present in the orchid plant. The commonly found phytochemicals are alkaloid, flavanoid, phenol, terpenoid, steroid and saponin.

“…Dihydrophenanthrenes, phenanthrenes, and benzyls are stilbenoids with an identical 1,2-distyrene skeleton. The substituents on their aromatic rings are mainly hydroxyl, methoxy, and p -hydroxybenzyl groups (Lin et al, 2005). In the ultraviolet spectrum, dihydrophenanthrene compounds, in general, have an α band at approximately 310 nm, a β band at approximately 250 nm, and a ρ band at approximately 280 nm.…”

Bletilla striata is a plant from the Orchidaceae family that has been employed as a traditional Chinese medicine (TCM) for thousands of years in China. Here, we briefly review the published studies of the last 30 years that were related to chemical constituents, pharmacologic activities, and clinical applications of B. striata. Approximately 158 compounds have been extracted from B. striata tubers with clarified molecular structures that were classified as glucosides, bibenzyls, phenanthrenes, quinones, biphenanthrenes, dihydrophenanthrenes, anthocyanins, steroids, triterpenoids, and phenolic acids. These chemicals support the pharmacological properties of hemostasis and wound healing, and also exhibit anti-oxidation, anti-cancer, anti-viral, and anti-bacterial activities. Additionally, various clinical trials conducted on B. striata have demonstrated its marked activities as an embolizing and mucosa-protective agent, and its application for use in novel biomaterials, quality control, and toxicology. It also has been widely used as a constituent of many preparations in TCM formulations, but because there are insufficient studies on its clinical properties, its efficacy and safety cannot be established from a scientific point of view. We hope that this review will provide reference for further research and development of this unique plant.
