“…Surprisingly, the spontaneous rooting observed in this study is contrary to the results reported by Silos-Espino et al (2007) for A. salmiana , in which 0.2 mg/L of IAA was necessary to generate a complete root system in 45 days. This response is common in Agave species and confirmed that A. salmiana does not require auxins to produce roots, similar to A. parrasana Berger (Santacruz-Ruvalcaba et al, 1999) and A. hybrid No.…”

“…Micropropagation comparisons reveal differences in terms of the type of explant used. For example, using cambium meristem or cylindrical core in A. salmiana , Silos-Espino et al (2007) obtained a yield of 20 axillary shoots in 45 days, which is 30% more efficient than the current study. These differences are attributed to the seed-plantlets used in this study as the main explant, as observed by Zhang et al (2013), where the explant and variety used had a direct impact on the shoot efficiency.…”

“…Additionally, the spontaneous rooting might be due the absence of BAP and its derivative because the presence of cytokinins inhibits the formation of roots and correct development of plants during the acclimatization process (Aremu et al, 2015). Most Agave species have high survival rates (80–98%) after acclimatization (Silos-Espino et al, 2007; Zhang et al, 2013; Chen et al, 2014). Based on these results, this study supports the massive use of seeds in the micropropagation of A. salmiana , which has been previously demonstrated to ensure large numbers of specimens, genetic variability generation, diversity, sanitation, and stable genetics (Portillo et al, 2007).…”

“…This technique also can provide material for crop improvement using molecular breeding tools (Flores-Benítez et al, 2007). Several studies of A. salmiana micropropagation that emphasize the economic and agricultural sustainability and preservation of its diversity have been published (Silos-Espino et al, 2007; Ramírez-Malagón et al, 2008)…”

“…Furthermore, agave nutritional properties have been widely documented (Silos-Espino et al, 2007). For example, carbohydrates are one of the most important metabolites for the Agave agroindustry (Mancilla-Margalli and López, 2006; Michel-Cuello et al, 2008; Arrizon et al, 2010) due to high accumulation of carbohydrates in the form of fructans, which are mainly composed of sucrose, fructose, and glucose (Mancilla-Margalli and López, 2006).…”

Micropropagation of Agave salmiana: Means to Production of Antioxidant and Bioactive Principles

Maguey, Agave salmiana, is an important plant for the “pulque” beverage and functional food industries; however, it has several constraints for elite and homogeneous plant production. In this study, a micropropagation process was established to generate in vitro plants. The effect of the method on metabolite content and antioxidant (AOX) activity in regenerated plants was evaluated. Young germinated plantlets were micropropagated from axillary shoots using Murashige and Skoog medium supplemented with L2 vitamins, 0.04 mg/L 2,4-dichlorophenoxyacetic acid and 10 mg/L 6-benzylaminopurine. Total soluble sugars from the aqueous fraction and total phenolic acids, total saponins, and AOX activity of the methanol fraction were determined in wild-type (WT) plants, in in vitro (IN) plants, and ex vitro acclimated plants (EN). The results showed that IN plants have a 50% lower soluble sugar content compared to WT, and EN. The total phenolic acids content was at least 30% higher in micropropagated (IN) and regenerated (EN) plants compared to WT. The total saponin content in IN, and EN plants was 36 and 25 times higher compared to WT. The AOX capacity of IN plants was on average three times higher compared to other treatments. However, no correlation was found between the AOX activity and total phenolic acids or total saponins. A negative and significant correlation (r = –0.927; p = 0.003) was found between the AOX activity and the total soluble sugars content. Micropropagated plants of A. salmiana have a different phytochemical content and bioactivity after the in vitro process compared to WT plants. The micropropagation process could be used as a platform for phytochemical enhancement of Agave plants.

Agave salmiana Otto ex Salm-Dyck has traditionally been used for the production of fermented beverage known as "pulque" that has recently gained acceptance as a functional food. However, the plant requires up to 10 years to be used as raw material. The objective of this work was to evaluate the antioxidant and bioactive principles of Agave salmiana during different stages of development. Wild grown plants from Coahuila, Mexico, were identified based on leaf and spine traits to obtain a representative sample from six different stages of development (I-VI) from 1 to 7 years old. Total phenolic content (TPC), antioxidant activity (AOX), as well as composition and content of flavonols and saponins by HPLC-MS-TOF and HPLC-ELSD-PDA were evaluated. Concentrations of TPC were found to be between 5 to 13 mg gallic acid equivalents/g, reaching a maximum at stage II. The AOX presented a negative tendency from stage I to stage VI (from 148 to 50 μmol Trolox equivalents/g respectively). Kaempferol, quercetin and five saponins were identified. Similar to AOX, flavonols presented a negative concentration tendency with a reduction of 65% between the stage I and VI. Plants of stage III and IV presented the highest content of saponins, particularly chlorogenin glycoside, containing 3.19 and 2.90 mg protodioscin equivalents/g, respectively. These data suggest that plants from stages I to IV may be used as a source of antioxidant and bioactive principles, and that the content of these metabolites could be used as a marker to determine the developmental stage of the plant.
