“…It is reported to contain caffeic acid, cyanogenic glycoside, ferulic acid, flavonols, flavonoid glycosides, and isoflavones (Yoshikawa et al, 2007 ). Antioxidant and cancer chemopreventive activities were reported previously (Van Diermen et al, 2009 , 2010 ). Asexual propagation is a useful method for multiplication of Sedum species.…”

“…Pharmacological investigations have revealed that Sedum species possess antiangiogenic, anticholinesterase, anti-inflammatory, antimicrobial, antinociceptive, antioxidant, antitumor, and hepatoprotective properties (He et al, 1998 ; Bonina et al, 2000 ; Kim et al, 2004 ; De Melo et al, 2005 ; Jung et al, 2008 ; Van Diermen et al, 2010 ; Dahpour et al, 2012 ; Ertas et al, 2014 ; Bensouici et al, 2016 ; Chen et al, 2016 ). Phytochemical investigations reveal the presence of several medical compounds in Sedum species like alkaloids, chlorogenic acid, chrysin, coumarins, cyanogenic glycoside, cyclotrisiloxane, eicosane, flavonoids (hesperetin, kaempferol, naringenin, and quercetin), hexadecanoic acid, neophytadiene, phenolic acids (caffeic and ferulic), and terpenes (Bonina et al, 2000 ; De Melo et al, 2005 ; Yoshikawa et al, 2007 ; Van Diermen et al, 2009 ; Dahpour et al, 2012 ; Morikawa et al, 2012 ; Beltrán-Orozco et al, 2013 ).…”

A promising micropropagation protocol has been systematically established and demonstrated for the enhanced production of carotenoids, tocopherol and fatty acids in shoot tissues of Sedum dasyphyllum. Shoot tip explants were grown on Murashige and Skoog (MS) medium. Different concentrations of N6-benzyladenine (BA) or thidiazuron (TDZ) alone or in combination with α-naphthaleneacetic acid (NAA) were tested in order to stimulate multiple shoot production. Ideal shoot induction (100%) and maximized shoot numbers (36.4) were obtained on explants cultured on media incorporated with 2 μM BA and 1 μM NAA combinations. The in vitro-developed shoots rooted best on half-strength MS media incorporated with 2 μM indole 3-butyric acid. Plantlets were effectively acclimatized in the greenhouse with 100% survival rate. The composition and contents of bioactive compounds such as carotenoids, tocopherol and fatty acids in shoot tissues of S. dasyphyllum were investigated using HPLC and GC-MS. The most abundant carotenoid in the shoot tissue was all-E-lutein (40.3–70.5 μg g−1 FW) followed by 9′-Z-neoxanthin (5.3–9.9 μg g−1 FW), all-E-violaxanthin (4.4–8.2 μg g−1 FW), and all-E-β-carotene (1.6–3.6 μg g−1 FW). The α-tocopherol contents of in vitro-raised shoots was 6.5-fold higher than shoots of greenhouse-grown plants. The primary fatty acids found in shoot tissues were α-linolenic acid (32.0–39.3%), linoleic acid (27.4–38.2%), palmitic acid (13.3–15.5%), and stearic acid (5.2–12.2%). In all, summarizing the findings, the micropropagated S. dasyphyllum showed significant enrichment of valuable bioactive carotenoids (92.3 μg g−1 FW), tocopherols (14.6 μg g−1 FW), and α-linolenic acid (39.3%) compared to their greenhouse counterparts. The protocol demonstrated here could be applied for the mass propagation and production of enhanced bioactive compounds from S. dasyphyllum with credibility.
