摘要

为了为提高桑黄孢的木屑栽培技术提供科学依据,本文对桑黄孢的营养成分、有效成分含量和子实体抗氧化活性进行了比较研究。结果表明:①培养方式对粗脂肪含量及测定的16种氨基酸[包括总必需氨基酸(EAA)、总非必需氨基酸(NEAA)、EAA/NEAA和EAA/总氨基酸(TAA)]含量影响不大,但对粗蛋白质、粗纤维和TAA含量影响较大;由此可见,木屑栽培的营养成分显著高于伐木栽培。(2)不同栽培方式对三萜含量影响不大,但对多糖、总黄酮和总酚含量影响较大,其中砍枝栽培显著高于木屑栽培。(3)不同栽培方式对抗氧化活性(ABTS和FRAP)有较大影响,其中伐木栽培显著高于木屑栽培。木屑栽培菇多糖、总黄酮、总酚含量及ABTS和FRAP活性均低于切条栽培,这可能与菌种、培养基配方和栽培工艺有关。研究结果为鲍氏菌栽培新技术的改良和推广提供了坚实的基础。

Effects of Cultivation Methods on the Nutritional Content, Active Component Content, and Antioxidant Activity of Fruiting Bodies of Sanghuangporus baumii (Agaricomycetes).

To provide a scientific reference for improving the sawdust cultivation of Sanghuangporus baumii, comparative studies were conducted on the contents of nutritional components and active components and the antioxidant activity of the fruiting bodies of S. baumii cultivated with sawdust and cut logs. The results indicate that, first, cultivation methods had little effect on the contents of crude fat and the measured 16 kinds of amino acids [including total essential amino acids (EAA), total nonessential amino acids (NEAA), EAA/NEAA, and EAA/total amino acid (TAA)], but had a great influence on the contents of crude protein, crude fiber and TAA. These results suggest that the nutritional content under sawdust cultivation was significantly higher than that under cut-log cultivation. Second, the cultivation methods had little effect on the content of triterpenoids but had a great effect on the contents of polysaccharides, total flavonoids and total phenols, which showed that cut-log cultivation was significantly higher than sawdust cultivation. Third, the cultivation methods had a great effect on the antioxidant activities (ABTS and FRAP), which showed that cut-log cultivation was significantly higher than sawdust cultivation. The contents of polysaccharides, total flavonoids, and total phenols and the ABTS and FRAP activities using sawdust cultivation were lower than those using cut-log cultivation, which may be related to the mushroom strains, cultivation medium formula and cultivation technology. The results provide a solid basis for the improvement and promotion of new cultivation technologies for S. baumii.

期刊介绍: The rapid growth of interest in medicinal mushrooms research is matched by the large number of disparate groups that currently publish in a wide range of publications. The International Journal of Medicinal Mushrooms is the one source of information that will draw together all aspects of this exciting and expanding field - a source that will keep you up to date with the latest issues and practice. The International Journal of Medicinal Mushrooms published original research articles and critical reviews on a broad range of subjects pertaining to medicinal mushrooms, including systematics, nomenclature, taxonomy, morphology, medicinal value, biotechnology, and much more.
