“…This is the first experiment to investigate the phenolic composition of the husked sand rice seeds, although the profile was different from that of the aerial parts of the plant. Several flavonoids, including rutin, quercetin, luteolin, and mangiferin, among others, were previously isolated from the aerial parts, whereas 12 such constituents in the plant seeds have been reported more recently . The difference observed between the present study and previous works could be attributed to the different plant parts used among these studies.…”

“…12 In addition, the flavonoid content in sand rice coat and kernel (351.2 and 335.7 μg rutin-equivalent g −1 , respectively) is greater than in millet, wheat, rice, peanut, and corn. 13 All of these results strongly suggest that sand rice is a potential food crop with high nutritional value. Therefore, understanding the changes in bioactive compounds in sand rice after cooking and digestion would lead to a better understanding of its potential effects on human health.…”

“…Further proximate and compositional analysis demonstrated that sand rice seed comprises 23.2% protein, 9.7% lipid, 45.0% carbohydrates, 8.6% crude fiber, and 5.0% ash, and that it is particularly rich in essential amino acids, linoleic acid, and iron compared with quinoa seed . In addition, the flavonoid content in sand rice coat and kernel (351.2 and 335.7 µg rutin‐equivalent g −1 , respectively) is greater than in millet, wheat, rice, peanut, and corn …”

BACKGROUND Sand rice (Agriophyllum squarrosum) is an underutilized pseudocereal bearing edible seeds. In this study, the phenolics and antioxidant activity of sand rice seeds after cooking and in vitro digestion were extensively investigated. RESULTS Total phenolic content (TPC) of the sand rice seeds was slightly increased whereas total flavonoid content (TFC) decreased after boiling. Furthermore, nine compounds were detected in the uncooked seeds, with hyperoside (169.19 ± 6.59 µg g−1 dry weight (DW)), protocatechuic acid (167.46 ± 7.21 µg g−1 DW), and rutin (83.15 ± 3.26 µg g−1 DW) as the major components. Apart from the bioaccessible phenolics in the aqueous fraction, these compounds retained in the solid residue of the porridge were released to varying degrees during simulated digestion. In addition, these phenolic extracts also exerted considerable antioxidant potency, which was positively correlated with their corresponding TPC, TFC, and phenolic profiles. CONCLUSION These results indicated that both boiling and in vitro digestive treatments could considerably enhance the release of bioactive compounds and thus contribute antioxidant properties to sand rice porridge. These findings suggest that sand rice seed is a potential functional food and an excellent natural antioxidant source. © 2019 Society of Chemical Industry

“…Onions treated by high-pressure processing increased various flavonoids extractability including isorhamnetin 3,4-diglucoside, and increased anti-inflammatory and antioxidant activities [ 32 ]. Isorhamnetin rutinoside was reported to have a significant antioxidant and anti-inflammatory effect on human peripheral blood mononuclear cells stimulated with phytohaemagglutinin [ 33 ]. In addition, isorhamnetin 3-glucoside, isolated from Cochlospermum religiosum , was reported to significantly retard selenite-induced cataract in vitro by virtue of its antioxidant properties [ 34 ].…”

Opuntia humifusa is a type of cactus whose fruits have been used in folk medicine for the treatment of several diseases. In the present study, we aimed to determine whether O. humifusa fruit water extract (OHE) has inhibitory effects against solar ultraviolet (sUV)-induced matrix metalloproteinase-1 (MMP-1) expression. In ex vivo human skin, we found that OHE suppressed sUV radiation-induced MMP-1 expression. The inhibitory effect of OHE was confirmed in human dermal fibroblasts. OHE treatment reduced sUV-induced MMP-1 expression by suppressing reactive oxygen species (ROS) generation and phosphorylation of c-Jun, a component of transcription factor activator protein 1 (AP-1). On the other hand, OHE recovered the tissue inhibitor of matrix metalloproteinase 1 (TIMP-1) and type 1 collagen production attenuated by sUV. As upstream signaling pathways for AP-1, MKK4-JNK, MEK-ERK, and MKK3/6-p38 phosphorylation were downregulated by OHE treatment. In addition, OHE exhibited DPPH radical scavenging activity. These findings demonstrate that OHE has a preventive effect against sUV-induced skin damage via suppression of pathways triggered by ROS.

Sand rice (Agriophyllum squarrosum) is an extensively cultivated psammophyte in the desert area of Asia for its sand stabilization ability (Qian et al., 2016;Zhao et al., 2014). For local people, sand rice has been popularly consumed as the comestible and medicine for hundreds of years (Xu et al., 2018). As reported, the nutritional value of sand rice is deemed to be comparable to that of quinoa (Chenopodium quinoa Willd.), who has gained global recognition with unique nutritional characteristics and adaptability (Zhang et al., 2018). Thus, the sand rice will be a potential crop as the alternative food for growing populations.Increasing demand for more sand rice production requires further understanding and processing them. In sand rice, starch is the most abundant carbohydrate making up 32.5%-51.2% (Peng et al., 2018). This starch is reported as an A-type starch with round shape smaller
