Traditional uses, chemical compositions and pharmacological activities of Dendrobium: A review
2023, Journal of EthnopharmacologyScorpionate ligand derived from 1-amino-9H-fluoren-9-ol and its metal (II) complexes as potential anticancer agents
2019, Chemical Data CollectionsCitation Excerpt :Fluorenones are an inevitable and important class of organic compounds that are found in rock extracts and other crude oils [7] as well as in diesel fuels [8]. Widespread interest has been developed on these molecules due to their interesting bioactive properties [9–11]. Fluorenone derivatives have been known to be used for the treatment of ophthalmic conditions [12].
Phloroglucinol enhances recovery and survival of cryopreserved Dendrobium nobile protocorms
2011, Scientia HorticulturaeCitation Excerpt :This species has been referenced in the Chinese literature as a valuable medicinal plant (Hu, 1970) and used in traditional Chinese medicine (Ye et al., 2002). In fact, 5 alkaloids from D. nobile had already been identified in 1965 (Okamoto et al., 1966), followed by a number of additional compounds in related species, including alkaloids (Suzuki et al., 1973), fluorenones and sesquiterpenoids (Talapatra et al., 1985, 1992), bibenzyls and phenathrenes (Majumder and Chatterjee, 1989), and sesquiterpene glycosides (Zhao et al., 2001). Reports indicate antibiotic effects and possible anti-cancer properties (Hu, 1970), as well as antitumor and antimutagenic activities (Lee et al., 1995; Miyazawa et al., 1997) of compounds isolated from crude plants extracts.
Phenols and a triterpene from Dendrobium aurantiacum var. denneanum (Orchidaceae)
2006, Biochemical Systematics and EcologyCitation Excerpt :TLC (CH2Cl2–MeOH, 9:1) of subfraction 6/2 (1.6 g) afforded kaempferol (7, 12 mg) (Ulubelen et al., 1980) and naringenin (8, 15 mg) (Shen et al., 1993). Subfractions 6/4 (1.2 g) was chromatographed on Sephadex LH-20 column with MeOH–CH2Cl2 (7:3) to provide dengibsin (9, 30 mg) (Talapatra et al., 1985) and dendroflorin (10, 11 mg) (Zhang et al., 2004). The compounds were identified conclusively by UV, IR, MS, 1HNMR and 13C NMR analysis.
