Djulis (Chenopodium formosanum Koidz.) is a cereal food and its antioxidant and pigment constituents may protect skin from photoaging, but conclusive experiments have not been carried out.
This investigation evaluates the effects of djulis extract as a functional supplement.
PATIENTS/METHODS: In this study, the effects of djulis functional drinks on the free radical scavenging activities, promotion of collagen synthesis and protection against oxidative stress and the effects of ultraviolet B (UVB)-irradiated of pUC119 DNA were explored. Thirty healthy subjects (aged 35-55 years old) were randomly allocated to djulis or placebo drinks groups (50 ml of a djulis/placebo drink daily for 8 weeks for each subject) in a double-blind crossover study.
The regular consumption of the djulis functional drinks significantly increased levels of the serum biochemical superoxide dismutase (SOD) and catalase (+9.5% and +124.8%) after 8 weeks, relative to baseline controls. The improvements in skin moisture, brightness, elasticity, crow's feet, texture, wrinkles, pores, and collagen content after 8 weeks in the djulis group were +13.3%, +3.8%, +13.2%, -21.8%, -12.1%, -11.0%, -1.4%, and +33.7%, respectively, relative to the baseline without treatment.
These work findings suggest the daily consumption of djulis drinks can protect the skin against oxidative stress-induced damage, delay skin aging and improve skin conditions.
蕺菜（Chenopodium formosanum Koidz.）是一种谷物食品，其抗氧化和色素成分可能有助于保护皮肤免受光老化，但尚未进行确凿的实验。
本研究评估蕺菜提取物作为功能性补充剂的效果。
患者/方法：在这项研究中，探讨了蕺菜功能饮料对自由基清除活性、促进胶原蛋白合成以及对氧化应激和紫外线 B（UVB）照射的 pUC119 DNA 的保护作用。30 名健康受试者（年龄 35-55 岁）被随机分配到蕺菜或安慰剂饮料组（每位受试者每天饮用 50ml 蕺菜/安慰剂饮料，持续 8 周），采用双盲交叉研究。
常规饮用蕺菜功能饮料 8 周后，血清生化超氧化物歧化酶（SOD）和过氧化氢酶水平分别显著升高（分别增加 9.5%和 124.8%）。8 周后，蕺菜组皮肤水分、光泽度、弹性、鱼尾纹、纹理、皱纹、毛孔和胶原蛋白含量的改善分别为+13.3%、+3.8%、+13.2%、-21.8%、-12.1%、-11.0%、-1.4%和+33.7%，与未经治疗的基线相比。
这些研究结果表明，每天饮用蕺菜饮料可以保护皮肤免受氧化应激引起的损伤，延缓皮肤衰老，改善皮肤状况。
