采用纸层析、紫外-可见光谱、红外光谱和液-质联用等技术对福建野生黄瑞木〔Adinandra millettii(Hook. et Arn.)Benth.〕果实红色素进行了分析研究。结果表明,该红色素主要含有矢车菊素-3-芸香糖苷(cyanidin-3-rutinoside)和矢车菊素-3-葡萄糖苷(cyanidin-3-glucoside)2种花色苷,呈鲜艳的红色,可作为天然保健食品的色素添加剂加以推广应用。
The paleoforest remains studied are distributed within a range of 18000 m^2 in the intertidal zone of the Qianhu Bay, Fujian Province. Eighty-nine ancient tree stumps can be clearly recognized in the paleoforest remains. Microscopic studies of 10 relatively low-carbonized stump samples definitely showed four species： Glyptostrobus pensUi （Staunt） Kouch, Schima superba Gardn., Cinnamomum Schaeffer, and Litsea Lam. The 14^C dating of some samples yielded the ages of 42560±350 to 〉43000 a B. P., corresponding to the late Late Pleistocene.
