“…Arundina graminifolia , commonly called ‘bamboo orchid’, is an important flower in the family Orchidaceae. It mainly grows in tropical and sub-tropical areas in Asia and has been used as a traditional medicinal plant in China and an ornamental flower in Singapore and Malaysia [ 26 , 27 , 28 ]. Unlike other orchids, it blooms throughout the year with flowering peaks from September to January.…”

Flowering in orchids is the most important horticultural trait regulated by multiple mechanisms. Arundina graminifolia flowers throughout the year unlike other orchids with a narrow flowering span. However, little is known of the genetic regulation of this peculiar flowering pattern. This study identifies a number of transcription factor (TF) families in five stages of flower development and four tissue types through RNA-seq transcriptome. About 700 DEGs were annotated to the transcription factor category and classified into 35 TF families, which were involved in multiple signaling pathways. The most abundant TF family was bHLH, followed by MYB and WRKY. Some important members of the bHLH, WRKY, MYB, TCP, and MADS-box families were found to regulate the flowering genes at transcriptional levels. Particularly, the TFs WRKY34 and ERF12 possibly respond to vernalization and photoperiod signaling, MYB108, RR9, VP1, and bHLH49 regulate hormonal balance, and CCA1 may control the circadian pathway. MADS-box TFs including MADS6, 14, 16, AGL5, and SEP may be important regulators of flowering in A. graminifolia. Therefore, this study provides a theoretical basis for understanding the molecular mechanism of flowering in A. graminifolia.

“…The family Orchidaceae is divided into 5 subfamilies, i.e., Epidendroideae, Orchidoideae, Vanilloideae, Cypripedioideae, and Apostasioideae [ 44 ]. So far, dimeric phenanthrenes have been reported from only two subfamilies, i.e., Epidendroideae (the genera Stanhopea, Bletilla, Pholidota, Pleione, Otochilus, Arundina, Bulbophyllum, Dendrobium, Monomeria, Cremastra, Agrostophyllum, Liparis, Cyrtopodium , Eria , Eulophia , Cirrhopetalum , Calanthe, Lusia, and Prosthechea ) and Orchidoideae (the genera Spiranthes and Gymnadenia ) [ 34 , 39 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ]. No biphenanthrenes have been found outside these two subfamilies.…”

A phytochemical investigation on the whole plants of Aerides multiflora revealed the presence of three new biphenanthrene derivatives named aerimultins A–C (1–3) and a new natural phenylpropanoid ester dihydrosinapyl dihydroferulate (4), together with six known compounds (5–10). The structures of the new compounds were elucidated by analysis of their spectroscopic data. All of the isolates were evaluated for their a-glucosidase inhibitory activity. Aerimultin C (3) showed the most potent activity. The other compounds, except for compound 4, also exhibited stronger activity than the positive control acarbose. Compound 3 showed non-competitive inhibition of the enzyme as determined from a Lineweaver–Burk plot. This study is the first phytochemical and biological investigation of A. multiflora.

The present study was aimed to assess the antibacterial activity of ethanolic extract obtained from leaves of Coelogyne brachyptera Rchb. f. For the current study, а panel of organisms including Staphylococcus aureus subsp. aureus Rosenbach (ATCC® 25923™) (mecA negative), S. aureus subsp. aureus Rosenbach (ATCC® 29213™) (mecA negative, Oxacillin sensitive, weak β-lactamase producing strain), S. aureus NCTC 12493 (mecA positive, Methicillin-resistant, EUCAST QC strain for cefoxitin), Escherichia coli (Migula) Castellani and Chalmers (ATCC® 25922™), E. coli (Migula) Castellani and Chalmers (ATCC® 35218™), Pseudomonas aeruginosa (Schroeter) Migula (ATCC® 27583™) were used. The antimicrobial susceptibility testing was done on Muller-Hinton agar by the disc diffusion method. The results of our study revealed the differential efficacy of ethanolic extract obtained from leaves of C. brachyptera on the test organisms. The ethanolic extract obtained from leaves of C. brachyptera revealed significant antibacterial activity against studied strains compared to control samples (96 % ethanol). A statistically significant increase (p <0.05) in the inhibition zone diameters of strain growth was 47 % for S. aureus subsp. aureus ATCC® 25923™, 40 % for S. aureus subsp. aureus ATCC® 29213™, and 44 % for S. aureus NCTC 12493. A non-significantly increase in inhibition zone diameters of E. coli strains' growth was also observed. The plant can be a source material to the herbal drug industry since it has some important antimicrobial components in the extracts that can be used for the development of therapeutic phytomedicine and phytoveterinary.
