In our research, twenty constituents, including three new ones, were isolated from artificially induced dragon's blood of Dracaena cambodiana, five of which are the same with those from natural dragon's blood. Dragon’s blood (Xue Jie in Chinese) is a red resin originally obtained from species of Dracaena (Dracaenaceae).Because of the limited resources, species from distinct plant genera, Daemonorops (Palmae), Croton (Euphorbiaceae) and Pterocarpus (Fabaceae) are used as alternative resources (Sousa et al. ; Dai, H.F.

Recent research has shown that the Dragon blood extract can cure gastric ulcer. This report represents the first genome-wide characterization of a Dracaena species in the Asparagaceae. The plant resin is used since ancient times as medicine, varnish, body oil, incense and dye. In the last half of the century, Chinese scientists have extensively investigated the production of dragon’s blood from these two Dracaena species, whereas these results have not been previously systematically summarized, as in the present paper. Here, we provided the first local reference DNA barcode library based on the second internal transcribed spacer (ITS2) for the molecular identification of SCM. Previous phytochemical studies on the plants of the genus Dracaena have led to the isolation of a number of phenolic compounds and a series of steroidal saponins [4] . Neighbor-joining trees based on Kimura 2-Parameter (K2P) genetic distances showed a 67.56% successful rate of species identification with ITS2 barcode. Dracaena cambodiana’s resin is used since ages as body oil, medicine, varnish, incense and dye. Dual-luciferase assays showed that the DcF3’H promoter was up-regulated by 6-benzyl aminopurine (6-BA) and down-regulated by methyl jasmonate (MeJA), and these results were consistent with transcription levels of DcF3’H in stems that were verified by quantitative real-time PCR (qPCR). In this study, we used zebrafish embryos as a platform to demonstrate the in vivo pro-angiogenic activity of dracorhodin perchlorate, the chemically synthesized analog of dracorhodin. ; Kartawinata, K. Taxonomy and uses of, d functional study of leaf traits and sap flow in, Jiang, Z.H. Dracaena Draco is by far the most popular landscaping feature plant for South coast and Sydney landscapes. Dracaena cambodiana Pierre ex Gagnep. Dragon's blood that is extracted from Dracaena plants has been widely used as traditional medicine in various ancient cultures. Access scientific knowledge from anywhere. mô tả khoa học đầu tiên năm 1934. However, the genetics of the genus Dracaena and the formation mechanism of dragon’s blood remain poorly understood. Published online: 18 Dec 2014. A maximum-likelihood phylogenomic analysis showed that the position of D. cochinchinensi was on the base of Nolinoideae. Sap of this plant turns bright red after coming in contact with air. Genome survey sequencing for the characterization of genetic background of Dracaena cambodiana and its defense response during dragon’s blood formation. In China, the red resin of Dracaena cambodiana Pierre ex Gagnep. ; Judd, W.S. and Dracaena cambodiana were successively discovered in southern China during the 1970s–1980s. A total of 4129 unique protein groups including 1083 differentially modulated in one (individual) or other (combined) treatments were discerned. This is for the first time that a dragon tree species has been reported from India. ITBBZD 1041). About: Researchers have discovered Dracaena cambodiana, a dragon tree species in the Dongka Sarpo area of West Karbi Anglong in Assam. Cellulase elicitor induced accumulation of capsidiol in, leaves during infection with fungal pathogen, Yang, M.H. We also discuss how ROS act as signal molecules to regulate cellular activities using stomatal movement as an example. This report represents the first genome-wide characterization of a Dracaena species in the Asparagaceae. This plant yields dragon’s blood- a bright red resin. Here, we generate the first draft genome reference assembly of an elite Chinese Dracaena species, Dracaena cambodiana, from next … These dracaena are a bit like a cross with a Dragons Blood tree with Dracaena Marginata! Cambodia, Laos, Thailand and Vietnam). Dracaena's narrow foliage may be completely green or may include stripes or edges of green, cream, red, and/or yellow. However, little is known about steroidal saponin biosynthesis and its regulation in D. cambodiana. Researchers have discovered Dracaena cambodiana, a dragon tree species in Dongka Sarpo area of West Karbi Anglong District in Assam. An update of the A. the orders and families of flowering plants: APG IV. As per the study in India, Dracaena genus belonging to family Asparagaceae is represented by 9 species and 2 varieties in Himalayan region, northeast and Island of Andaman and Nicobar Islands. The promoter sequence contained cis-acting elements related to various environmental stresses and hormones responses.

Hình ảnh The dragons blood I bought is a mix of resin from Dracaena cochinchinensis and Dracaena cambodiana. It is a major medicinal in traumatology and is also used to treat bleeding in the upper GI tract. In this study, a 759-bp promoter region of DcF3’H was isolated from Dracaena cambodiana. India’s first dragon’s blood tree discovered in the Chirimukam (Dongkamukam) village of West Karbi Anglong, Assam, is the first report of the Dragon tree species in India. ; Yang, C. Ma, C.J. In our research, twenty constituents, including three new ones, were isolated from artificially induced dragon's blood of Dracaena cambodiana, five of which are the same with those from natural dragon's blood. upon ethylene and abscisic acid treatment. However, neither morphological features nor common DNA regions are ideal for identification of Dracaena spp. DcHLH1, a bHLH transcription factor identified in yeast one-hybrid screening, was capable of both binding to the promoter and activating the transcription of DcF3’H by ~10-fold. DcHLH1, a bHLH transcription factor identified in yeast one-hybrid screening, was capable of both binding to the promoter and activating the transcription of DcF3’H by ~10-fold. To meet increasing demand for dragon’s blood the recent overexploitation has resulted in rapid depletion of plant. Dracaena cambodiana is a narrow-distributed species, which is found in Yunnan, Guangxi, and Hainan provinces in China, Laos, Vietnam, Thailand and Cambodia. There are the two main causes of raw material of dragon's blood in China relying on, Furthermore, 172 fungi strains were isolated from. The American diet is filled with processed foods, high fructose corn syrup, high sugar and trans fats.

A new steroidal saponin from dragon's blood of Dracaena cambodiana. Meanwhile, although multiple Dracaena spp. ISSN 1932-6203 However, the genetics of the genus Dracaena and the formation mechanism of dragon’s blood remain poorly understood. The reads were assembled into 2,640,704 contigs with an N50 length of 1.87 kb, and a 1.05 Gb assembly was finally assembled with 2,379,659 scaffolds. Genus: Dracaena (From Greek ‘drakaina‘ meaning a female dragon – a reference to the reddish resin that exudes from the bark and leaves, supposedly resembling dragon’s blood) Abstract: Dragon’s blood that is extracted from Dracaenaplants has been widely used as traditional medicine in various ancient cultures. Other than dragon’s blood several antifungal and antibacterial compounds, antioxidants, flavonoids etc., have been extracted from various parts of this plant. Gene ontology consortium: Going forwar, databases from NCBI-nr database for rapid annotation, Hématy, K.; Cherk, C.; Somerville, S. Hos, Rejeb, K.B. Dracaena cambodiana’ s resin is used since ages as body oil, medicine, varnish, incense and dye. PLOS ONE 2018, 13 (12) , e0209258. ... Dracaena cambodiana was discovered in China during the investigation of sustainable traditional medicine resources in the 1980s, and this ; Zheng, S.; Wang, X.H. In the APG IV classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Dragon's blood is a traditional medicine used in many countries of many cultures because of its various therapeutic uses, and its main bioactive compounds are flavonoids, which mainly exhibit antitumor and antimicrobial activities. Flavonoid 3′-hydroxylase (F3’H) is an enzyme that synthesizes 3′-hydroxylated flavonoids. DcF3’H plays a vital role in determining the flavonoid content during the production of dragon′s blood; however, the regulation of DcF3’H expression in Dracaenas plants is poorly understood.
