Sweetspire (Itea) is the only plant that accumulates rare sugars d-allulose and allitol. However, no reports have indicated that sweetspire has a beneficial physiological activity in mammalians. We have examined the effect of dietary dried sweetspire powder (SP) on body fat accumulation in rats fed with a high-fat diet. Twenty-four male Wistar rats were randomized into three groups, the control (C), SP, and rare sugar (RS) groups. The SP diet contained 5% SP (contained 0.4% d-allulose and 0.6% allitol in the diet), and the RS diet contained the same amount of rare sugars as the SP diet. All rats were given free access to the experimental diets for 8 weeks. The percentages of intra-abdominal adipose tissue and total body fat were significantly lower in the SP group than in the C group, suggesting that SP has an anti-obesity effect. Furthermore, this anti-obesity effect may be attributed to the rare sugars in SP.
甜叶悬钩子（Itea）是唯一能积累稀有糖 d-阿洛酮糖和阿糖醇的植物。然而，目前尚无报道表明甜叶悬钩子在哺乳动物中具有有益的生理活性。我们研究了日粮中添加干燥甜叶悬钩子粉（SP）对高脂肪饮食喂养大鼠体脂积累的影响。24 只雄性 Wistar 大鼠随机分为三组，即对照组（C）、SP 组和稀有糖（RS）组。SP 组日粮含有 5%的 SP（日粮中含有 0.4%的 d-阿洛酮糖和 0.6%的阿糖醇），RS 组日粮含有与 SP 组相同量的稀有糖。所有大鼠均可自由摄入实验日粮 8 周。与 C 组相比，SP 组大鼠的腹腔内脂肪组织百分比和总体脂肪百分比显著降低，表明 SP 具有抗肥胖作用。此外，这种抗肥胖作用可能归因于 SP 中的稀有糖。
