“…It was found that the ORAC radical scavenging potential is higher for A. arborescens than for A. barbadensis, while the DPPH assay indicated a reversed order, without a statistic signi cance [3]. When ORAC values of seven Aloe species were compared, the highest value was reported for A. arborescens (2135.1 µmol TE/100 g FW), which is signi cantly higher than that for A. ferox (525.72 µmol TE/100 g FW), and A. barbadensis (1234.4 µmol TE/100 g FW) [10]. In the study conducted by Cardarelli et al (2017), the scavenging activity pro les obtained by DPPH and ORAC assays, followed the trend A. marlothii < A. ferox < A.arborescens < A. barbadensis [1].…”

Although a vast number of Aloe species are known, only the Aloe vera and Aloe arborescens species are currently used by cosmetic and pharmaceutical industries. Therefore, the current study aims to complete the existent literature data with new information on the phytochemical composition of some lesser-known Aloe species, with the main focus on carotenoids and fatty acids. Among the analyzed species, Aloe aculeata and Aloe ferox had the highest content in carotenoids, the major pigments being lutein and β-carotene (according to HPLC analysis). The fatty acid profile of each Aloe species was analysed by GC-MS. Linolenic and linoleic acids were the major polyunsaturated fatty acids found in higher percent in Aloe ferox, Aloe spectabilis and Aloe marlothii. Instead, Aloe aculeata proved to have a distinct fatty acid profile, rich in monounsaturated fatty acids. Species such as Aloe arborescens and Aloe marlothii proved to have the highest antioxidant potential according to data of DPPH, ORAC, HPS assays, even if the richest one in vitamin C was found to be Aloe spectabilis. Though the scientific research is mainly focused on the common species Aloe barbadensis, current data suggests that other Aloe species could receive more attention from industry part, being great sources of bioactive compounds.

“…The phytochemicals in the Aloes may protect ascorbate from degradation in vivo [9]. From all known 500 species, Aloe barbadensis also known as A. vera, respective A. arborescens and A. ferox have the highest commercial importance [10]. The best-known and the most studied one A. barbadensis proved also its clinical effectiveness [11].…”

“…Therefore, the idea of using UV-B irradiation on sprouts was put forward. On the one hand, UV-B has been shown to inhibit the growth of microorganisms and prevent spoilage by inducing the production of the secondary metabolites of polyphenols (Lai et al, 2016). On the other hand, it can reduce the loss of water and keep the sprouts fresh and tender by inducing morphological changes within the plants (Namli et al, 2014).…”

Summary The production patterns and nutritious qualities of mung bean sprouts are in line with the consumption needs of modern people. This study was conducted to explore the effects of low doses of UV‐B irradiation on the 3‐day growth period of mung bean sprouts. The results showed that, when mung bean sprouts were irradiated with UV‐B (0.738 kJ m−2) for 1 h per day, their total phenolic content increased by 22.80%, and the activity of polyphenol oxidase decreased by 45.45%. Hypocotyl epidermis stomata were closed, reducing water loss and the opportunity for microbes to invade plants, leading to the maintenance of freshness of the sprouts. In conclusion, UV‐B irradiation for 1 h per day during the growth of mung bean sprouts can effectively improve their preservation. This method is a low‐cost, environmental friendly and pollution‐free physical preservation technique, and it has good application prospects.
