Extract from endophytic isolates stimulates seed germination of the host and protocorm development of non-host orchids.

We isolated endophytic strains from the healthy roots, stems, and leaves of to investigate their plant growth-promoting activities in vitro. Subsequently, Indole acetic acid (IAA) was quantified and the gene (responsible for IAA synthesis in fungi) was amplified and sequenced. Finally, a germination assay was performed with seeds of and a plant growth assay with protocorms of to test their plant growth-promoting activities.

Antidiabetic potential of four species of mushrooms from Nepal.

People use mushrooms to treat diabetes mellitus. We studied the antidiabetic potential of four mushrooms using porcine pancreatic α-amylase inhibitory activity and alloxan-induced diabetic mice. Methanolic extracts of all mushrooms were effective in inhibiting α-amylase activity.

Bioactive secondary metabolites in Sm. and their biological activities: A review.

Sm. is an important medicinal plant used to treat a variety of diseases through traditional medicine systems such as Ayurveda, Tibetan traditional medicines, Chinese traditional medicines, and others around the world. The IUCN red list has designated it as "vulnerable" due to a decline in wild population by over-exploitation, habitat degradation, illegal collection for trade and traditional use.

Characterization and Utilization of the Elusive α,β-Unsaturated -Tosyliminium: the Synthesis of Highly Functionalizable Skipped Halo Enynes.

A formal haloalkynylation of allenamides has been described for the synthesis of highly stereo- and regioselective skipped halo enynes. Exclusive γ-regioselectivity is achieved through the intermediacy of a conjugated -tosyliminium intermediate-direct evidence for the formation of which was validated by NMR and HRMS. Quantum mechanical computations reveal that the reactive intermediate geometry is key to controlling the 1,2- or 1,4-regioselectivity of alkyne interception.

Antioxidant, anticancer and antimicrobial effects of developed protocorms of .

seed germination and protocorms formation were successfully established in traditionally used . Fresh protocorms (178.34 g - 183.

Cytotoxic effect of selected wild orchids on two different human cancer cell lines.

Majority of the orchid species are used in the traditional medicines for the treatment of several diseases. They are the sources of polysaccharides, phenanthrenes, bibenzyl derivatives, revesteral, stilbenoids and polyphenol compounds. This study explored the cytotoxic activity of seven wild orchid species and identification of medicinally active compounds.

Isolation, characterization, and plant growth-promoting activities of endophytic fungi from a wild orchid .

Endophytism is one of the widely explored phenomena related to orchids and fungi. Endophytic fungi assist plants by supplementing nutrient acquisition, and synthesis of plant growth regulators. is an epiphytic orchid that has a great diversity of endophytic fungi.

Assessment of Antioxidant and Cytotoxic Activities of Extracts of .

is an epiphytic orchid found in south Asia including Nepal and China. This orchid species is widely used in traditional Chinese medicine (TCM) for the treatment of cancer, diabetes, cataracts, and fever. The objectives of the present research were to assess the antioxidant and cytotoxic properties of its stem's extracts with the identification of bioactive secondary metabolites.

Antioxidant and cytotoxic activities of Dendrobium moniliforme extracts and the detection of related compounds by GC-MS.

Background: The medicinal orchid Dendrobium moniliforme contains water-soluble polysaccharides, phenanthrenes, bibenzyl derivatives, and polyphenol compounds. This study explored the antioxidant and cytotoxic activities of D. moniliforme extracts and detected their bioactive compounds.
