Abstract

The bioactivities of crude polysaccharides from leaves (L-Ps) and flowers (F-Ps) of Schnabelia terniflora (Maxim.) P. D. Cantino were studied, and the characteristics of purified fractions were analysed by HPLC, HP-GPC and NMR. L-Ps exhibited strong DPPH radical scavenging activity (IC₅₀ value of 251.53 ± 4.62 μg/mL) and tyrosinase inhibition (IC₅₀ value of 163.52 ± 2.59 μg/mL). However, the maximum moisture absorption (74.67 ± 1.53%) and retention (68.00 ± 3.61%) abilities were observed in F-Ps. Two main fractions separated by DEAE-Sepharose fast flow column from L-Ps were eluted with 0.1 and 0.3 M NaCl, while one main fraction from F-Ps was eluted with 0.1 M NaCl. Purified fractions were obviously different in monosaccharide composition, molecular weight and ¹H NMR and ¹³C NMR spectra. Therefore, the current manuscript can provide an important evidence for the potential development of L-Ps and F-Ps as promising ingredients in cosmetics industry.

燕尾莲多糖的鉴定及皮肤保护活性研究。

山参叶粗多糖和花粗多糖的生物活性研究采用HPLC、HP-GPC、NMR等方法对其纯化组分进行了表征。L-Ps具有较强的DPPH自由基清除能力(IC50值为251.53±4.62 μg/mL)和酪氨酸酶抑制能力(IC50值为163.52±2.59 μg/mL)。而F-Ps的吸湿率(74.67±1.53%)和保湿率(68.00±3.61%)最高。用DEAE-Sepharose快速流柱洗脱L-Ps的两个主要馏分，分别用0.1和0.3 M NaCl洗脱，用0.1 M NaCl洗脱F-Ps的一个主要馏分。纯化组分在单糖组成、分子量、1H NMR和13C NMR谱上存在明显差异。因此，本文为L-Ps和F-Ps在化妆品行业的发展潜力提供了重要证据。

期刊介绍： The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
