“…In an antioxidant activities study, it was observed that leaves from tissue-cultured plants exhibited higher DPPH, ABTS and FRAP values compared to leaves from conventionally propagated plants. Studies by Amoo et al [ 36 ] and Bhattacharyya et al [ 37 ] on Aloe arborescene and Dendrobium thyrsiflorum , reported similar findings. The strong antioxidant activities in plant extracts could be due to the presence of high concentrations of secondary metabolites such as phenolics, tannins and alkaloids contents.…”

“…The addition of 30 g/L sucrose was found to be the optimum for the growth of Thymus hyemalis compared to other types of carbon sources including glucose, fructose, mannitol and sorbitol [ 17 ]. The studies implied that a sucrose concentration higher than 30 g/L results in a decrease in the multiplication and growth rate of plants [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. These findings were in agreement with the present study in which 30 g/L of sucrose was established as the optimum for the growth of C. nutans .…”

Clinacanthus nutans, commonly known as Sabah snake grass, is one of the more important medicinal plants in Malaysia’s herbal industry. C. nutans has gained the attention of medical practitioners due to its wide range of bioactive compounds responsible for various biological activities, such as anti-cancer, anti-venom and anti-viral activities. Due to its high pharmacological properties, the species has been overexploited to meet the demands of the pharmaceutical industry. The present study was conducted to establish a suitable in vitro culture procedure for the mass propagation of C. nutans. Murashige and Skoog (MS) basal medium, supplemented with different types of cytokinins, auxins, basal medium strength and sucrose concentrations, were tested. Based on the results, a full-strength MS basal medium supplemented with 12 µM 6-benzylaminopurine (BAP) and 30 g/L sucrose was recorded as the best outcome for all the parameters measured including the regeneration percentage, number of shoots, length of shoots, number of leaves and fresh weight of leaves. In the analysis of the phenolics content and antioxidant activities, tissue-cultured leaf extracts assayed at 100 °C exhibited the highest phenolic content and antioxidant activities. The propagation of C. nutans via a plant tissue culture technique was recorded to be able to produce high phenolic contents as well as exhibit high antioxidant activities.

“…Result concluded that among all the extracts ethanol extract showed strongest potential as antioxidant agent. Bhattacharyya et al, (2015) also investigated antioxidant property of different extracts of Dendrobium thyrsiflorum stem, leaf and root of mother as well as in vitro raised plants, by applying DPPH radical scavenging activity and FRAP assay. In the result they found that methanol extract of in vitro raised indirect shoot organogenesis was found most active than other in vitro plant and stem, leaf and root of mother plant, also the methanol leaf extract exhibited highest potential among all the extract of leaf, stem and root of mother plants.…”

“…Dendrobium thyrsiflorum Rchb. f. which is distributed in South China has been reported effective in treatment of various chronic disorders and anti-blood coagulant (Bhattacharyya et al 2015). Due to the over-exploitation of wild resources and narrow distribution, the wild populations of D. thyrsiflorum are severely threatened.…”

Dendrobium thyrsiflorum Rchb.f., a native species to China, is widely used as an important garden flower and a traditional Chinese medicine. Herein, the complete chloroplast (cp) genome of D. thyrsiflorum was deciphered by high-throughput sequencing. The cp genome exhibited a typical quadripartite cycle of 151,686 bp in length, comprising of a pair of inverted repeats (IRa and IRb) of 26,293 bp which were intersected by a large single copy (LSC) region of 84,749 bp and a small single copy (SSC) region of 14,351 bp. A total of 126 genes were de novo assembled in this cp genome, including 78 protein genes, 40 tRNA genes and 8 rRNA genes. Among these genes, 86 genes (22 tRNAs and 64 coding genes) were single copy, the rest were two-copy genes, and the average of GC content of the whole genome is 37.55%. Phylogenetic trees showed that the D. thyrsiflorum was closely related to D. devonianum . This study provides molecular information for future evolution, genetic and molecular biology studies of Dendrobium .
