本研究报道从睡眠剥夺（ＳＤ）４８—７２ｈ的灵长类原宗（ｐｒｉｍｉｔｉｖｅｓｔｏｃｋ）Ｔｕｐａｉａｂｅｌａｎｇｅｒｉｃｈｉｎｅｎｓｉｓ（ＴＢＣ）提取内源性“睡眠因子”（ｓｌｅｅｐｆａｃｔｏｒ）Ｓ２Ｃ和Ｓ４Ｂ。收集的尿液经超滤，清液冻干经ＳｅｐｈａｄｅｘＧ１５分离得到ＦｒａｃｔｉｏｎⅠ－Ⅴ。活性测定发现Ｆｒａｃｔｉｏｎ－Ⅲ（Ｓ２Ｃ）呈现显著δ－增强促眠效应。经ＳｅｐｈａｄｅｘＧ２５和ＳｅｐｈａｄｅｘＬＨ２０进一步净化的Ｓ４Ｂ也呈现显著δ－增强促眠效应。
This study reports the extraction of endogenous “sleepfactor” S2C and S4B from Tupaia belangerichinensis (TBC), a primitive stockstock 48-72 h after sleep deprivation (SD). Urine collected by ultrafiltration, supernatant lyophilized by SephadexG15 FractionⅠ-Ⅴ. Activity assay found that Fraction-Ⅲ (S2C) showed significant δ-enhancing hypnotic effect. S4B, which was further purified by Sephadex G25 and Sephadex LH20, also exhibited a significant delta-enhancing hypnotic effect.
