摘要:

为了提高可食性膜的透明度和阻隔性,制备一种速溶的普鲁兰多糖-明胶可食性膜。将普鲁兰多糖添加到明胶膜中,普鲁兰多糖和明胶的添加质量比为2∶5(PG2)。在此配比下,普鲁兰多糖-明胶可食性膜的抗拉强度是明胶可食性膜的120%,氧气透过率是明胶可食性膜的1/13。可食性膜PG2中普鲁兰多糖和明胶分子间具有较强的氢键作用,并且此时可食性膜具有较好的相容性,因此使可食性膜PG2抗拉强度增强和氧气透过率降低。可食性膜PG2具有较低的氧气透过率(0.15 mL/(m2•d))、较高的抗拉强度(97.21 MPa)和溶水时间(29.5 s),而且具有不透油和低水蒸气透过率(109.08 g/(m2•d))的性质,因此,可食性膜PG2是适合应用于可食性内包装的材料。

Abstract:

Objective: To isolate and identify the chemical constituents from the flowers of Chinese Fringetree
(Chionanthus retusa Lindl et Paxt). Methods: The chemical constituents were isolated and purified by sequential
column chromatographies on silica gel, Sephadex LH-20 and semi-preparative HPLC, and their chemical structures were
elucidated by spectroscopic methods. Results: A total of ten compounds were obtained and they were chemically identified
as quercetin-3-methyl ether-7-O-α-L-arabinofranosyl(1→6)-β-D-glucopy–ranoside (1), eriodictyol-7-O-β-D-glucoside (2),
acacetin-7-O-α-L-rhamnopyranosyl (1→6)-β-D-glucopyranoside (3), myricetin-3-O-β-D-glucopyranoside (4), luteolin-7-
O-β-D-glucoside (5), kaempferol-3-O-β-D-glucoside (6), and luteolin (7), myricetin (8), apigenin (9), and quercetin (10),
respectively. Conclusions: The compounds 1 through 6 were identified for the first time in the flowers of this plant, which
have been reportedly to possess potent antioxidant capacity.

Key words: Chinese fringetree flower(Chionanthus retusa Lindl et Paxt), flavonoids, chemical constituents
