Geodorum densiflorum (=Eulophia picta (R.Br.) Ormerod) is highly vulnerable to various environmental factors, yet it is renowned for
its significant therapeutic properties, largely due to its key chemical components. Its flavonoids, alkaloids, and terpenoids play a
crucial role in delivering a wide array of health benefits, from antioxidant and anti-inflammatory effects to antimicrobial and analgesic
properties. These compounds make Geodorum densiflorum a valuable species in traditional medicine and modern therapeutic
applications. Mycorrhizal studies revealed the association of Rhizoctonia solani in its roots. Chloroplast studies disclosed the
presence of 132 genes in the whole chloroplast genome, comprising 36 tRNA, 8 rRNA, and 76 protein-coding genes. By squash
technique, karyotype was identified as 2C type and the chromosome count was observed as 2n=54. Methanol extract of pseudobulbs
showed slight analgesic effect. Antioxidant activity of the stems and tubers ranged from very strong to minimal. Extracts showed a
substantial way to obtain new therapeutic agents from this species against sedative, anxiolytic, and associated central nervous
system disorders at a higher dose (400 mg/kg p.o.). Pyridinium, 2-Piperidinone, (E)-9-Octadeconoic acid ethyl ester (3.891%), 1-
amino-chloride (3.305%), 1H-Pyrrole-2-Carbonitrile (3.778%), and 4H-Pyran-4-one, 3,5-dihydroxy-2-methyl-(3.274%), N-[4-bromon-
butyl]-(4.004%), exhibit a range of biological activities. FTIR analysis detected distinct peak values and their corresponding
functional groups, indicating the existence of hydrogen-bonded alcohols, nitrogen compounds, phenols, bromides, alkenes, alkanes,
aliphatic esters, and aromatic groups in the extract. The ethyl acetic extract of G. densiflorum has shown both cytotoxicity and
antibacterial activity against Bacillus cereus, B. subtilis, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, and
Staphylococcus aureus. In order to examine the sedative and anxiolytic properties of root extracts, many mice behavioral models
were employed, including the open field, hole cross, thiopental sodium-induced hypnosis, and elevated plus maze tests. The
ethanolic extract exhibited potent inhibitory action against strains of MRSA and MSSA. Treatment with GDL resulted in a reduction
in WNT and an upregulation of FAS and FADD expression. AgNPs effectively inhibit the growth of Ehrlich ascites carcinoma (EAC)
cells and anti-cancer characteristics against GSCs, MCF-7, and BxPC-3 cells. In vitro propagation seems to be the only alternative
way for increasing number of its populations and to conserve the species. A high rate of seedling development is achieved when
NAA levels are kept low and BAP levels are high. Tomato extract has been identified as the most effective organic additive, while ½
MS medium proves to be the best for seed germination. BAP stands out as the most effective cytokinin for promoting rhizomemediated
proliferation. TDZ appears to be beneficial for rapidly generating leafy shoots. Additionally, a combination of IAA and BAP,
supplemented with activated charcoal, results in the production of healthy plantlets.
