摘要:

筛选适宜川贝母(Fritillaria cirrhosa)胚性愈伤组织增殖和活性物质积累的最佳培养方式,为川贝母在短期内实现快速增殖与高效富集次生代谢产物提供参考。采用3种方式(“固体-固体”“固体-液体”及“固体-液体-固体”)培养川贝母胚性愈伤组织,40 d后比较其结构分化、生长量、体外抗氧化能力及活性物质积累的差异。结果表明:不同培养方式的川贝母胚性愈伤差异较为显著,其中,“固体-液体-固体”培养各方面表现均为最优。(1)结构分化:该培养的愈伤组织形态均一、质地紧实、色泽鲜明,细胞核形态规则、分布均匀,原形成层结构清晰,细胞呈现出典型的胚性特征。(2)增殖系数:该培养的愈伤组织增殖倍数为1.45倍,分别是“固体-固体”与“固体-液体”培养的2.84倍和1.93倍。(3)体外抗氧化能力:该培养的愈伤组织具有较高的DPPH清除活性(47.55%)和FRAP(720.95 μmol⋅L-1),较“固体-固体”(40.41%和482.86 μmol⋅L-1)与“固体-液体”培养(44.15%和694.68 μmol⋅L-1)均有显著优势。(4)活性物质积累:该培养的胚性愈伤组织可溶性糖(56.15 mg⋅g-1)、总黄酮(2.06 mg⋅g-1)、总酚(1.44 mg⋅g-1)及西贝母碱(0.25 mg⋅g-1)的质量分数均最高,分别是“固体-固体”培养的1.07、1.15、1.66和1.39倍及“固体-液体”培养的1.23、1.11、1.13和1.19倍。本研究结果为川贝母次生代谢产物的规模化生产及再生体系的建立提供了理论依据与技术支撑。

Abstract:

The aim of this study was to screen an optimal culture method for the growth and bioactive metabolite accumulation of Fritillaria cirrhosa D. Don embryogenic callus, thereby providing a reference for the rapid proliferation and efficient enrichment of its secondary metabolites within a short period. Three culture methods, namely “solid-solid”, “solid-liquid” and “solid-liquid-solid”, were adopted to culture the embryogenic callus of F. cirrhosa. After 40 days of culture, structural differentiation, growth yield, in vitro antioxidant capacity, and bioactive metabolite accumulation were compared between the treatments. Significant differences were observed among the three culture methods for the embryogenic callus of F. cirrhosa, with the “solid-liquid-solid” mode showing the best overall performance. (1)Structural differentiation: The callus cultured by “solid-liquid-solid” mode showed uniform morphology, compact texture, and bright color. The cell nucleus was regular in shape and evenly distributed. The procambial bundle structure was well-defined, and the cells exhibited typical embryogenic characteristics. (2)Proliferation coefficient: The proliferation multiple of the callus under this system was 1.45, which was 2.84 and 1.93 times that of the “solid-solid” and “solid-liquid” cultures, respectively. (3)In vitro antioxidant capacity: The callus from the “solid-liquid-solid” culture exhibited strong DPPH radical scavenging activity(47.55%) and a high FRAP value(720.95 μmol⋅L-1), both of which were significantly superior to those of the “solid-solid” culture (40.41%, 482.86 μmol⋅L-1) and the “solid-liquid” culture(44.15%, 694.68 μmol⋅L-1). (4)Bioactive metabolite accumulation: The embryogenic callus in this group exhibited the highest levels of soluble sugar(56.15 mg⋅g-1), total flavonoids(2.06 mg⋅g-1), total phenolic(1.44 mg⋅g-1), imperialine(0.25 mg⋅g-1). These values were 1.07, 1.15, 1.66, and 1.39 times as high as those of the “solid-solid” culture, and 1.23, 1.11, 1.13, and 1.19 times as high as those of the “solid-liquid” culture, respectively. This study provides a theoretical basis and technical support for the large-scale production of secondary metabolites and the establishment of a plant regeneration system for F. cirrhosa.
