索绰络氏英和家族既是清代满族著名翰林家族,也是著名文学家族,共涌现出六名翰林、八位诗人,居满洲士族之冠。之所以成为文学家族,与其家族自觉的文化传承密切相关,同时,家族成员的自身努力和广泛的文学交游也起了促进作用。英和文学家族在文学创作方面成就可观,多有可述。尽管由于种种原因特别是“政事之余”的创作和诗作(诗集)的散佚,该家族没有出现一流诗人,但不能掩饰这个“满洲科第第一人家”作为一个文学家族群体的存在。探讨英和家族成员的文学活动和文学创作,对于认识清代中叶满洲文学家族的兴起以及八旗文学的兴盛都具有一定的认识意义。

该研究基于近红外光谱技术建立了何首乌在蒸制过程中多糖含量变化的快速定量模型。采用蒽酮浓硫酸法测定了不同蒸制时间何首乌的多糖含量并结合采集的近红外光谱数据建立模型,以校正集相关系数(R^(2)_(c))、预测集相关系数(R^(2)_(p))、交叉验证集均方根误差(RMSECV)和预测集均方根误差(RMSEP)作为评价指标,考察了不同预处理方法和变量筛选方法的效果。结果显示,随着蒸制时间的延长,何首乌多糖含量先上升后下降并趋于平稳,采用平滑+变量标准化+随机蛙跳变量筛选建立的偏最小二乘法回归模型的R^(2)_(c)=0.96,RMSECV=0.74,R^(2)_(p)=0.96,RMSEP=0.28;外部预测相对偏差小于3.0%。所建立的多糖含量定量模型质量较高,预测能力较强,可为探索何首乌炮制工艺标准化及质量评价提供参考。
