BACKGROUND & AIMS:
:In this study, the compositions of Ophiocordyceps longissima mycelia, synnemata, and fruiting bodies were first analyzed in order to clarify its chemical basis for development as a health food or medicine. We found that the contents of crude protein, polysaccharides, and macroelements were highest in mycelia, whereas effective components, including mannitol, ergosterol, adenosine, inosine, Zn, and Se, were lowest in mycelia. Polysaccharide, mannitol, and ergosterol levels in synnemata (2.33, 4.54, and 0.66 g/100 g, respectively) were similar to those in fruiting bodies, but was significantly different from those of mycelia (4.79, 1.77, and 0.43 g/100 g). Trehalose content in fruiting bodies (2.15 g/100 g) was >4 times higher than that in synnemata (0.5 g/100 g). Adenosine content in fruiting bodies (0.024 g/100 g) was 3-4 times higher than that of synnemata, whereas inosine, cytosine, guanosine, and uridine (0.093, 0.145, 0.053, and 0.073 g/100 g) were highest in synnemata. Cu and Se were lower in mycelia (3.30 × 10⁻⁴ and 3.1 × 10⁻⁵ g/100 g) than in synnemata (1.85 × 10⁻³ and 7.2 × 10⁻⁵ g/100 g) and fruiting bodies (1.67 × 10⁻³ and 4.3 × 10⁻⁵ g/100 g). As, Hg, Cd, and Pb in mycelia were under the limit of edible fungus health standard; Pb was not found, but Cd, Hg, and As were detected in fruiting bodies. These findings suggest that O. longissima could be utilized in different culture methods according to market demand and might be a possible health food or medicinal resource.
背景与目标:
:在这项研究中,首先分析了长麦冬菌菌丝,结膜和子实体的成分,以阐明其作为保健食品或药物发展的化学基础。我们发现,菌丝中粗蛋白,多糖和大量元素的含量最高,而有效成分包括甘露醇,麦角固醇,腺苷,肌苷,锌和硒在菌丝体中最低。结膜中多糖,甘露醇和麦角固醇的水平(分别为2.33、4.54和0.66 g / 100 g)与子实体中的相似,但与菌丝体的多糖(4.79、1.77和0.43 g / 100 g)显着不同)。子实体中的海藻糖含量(2.15 g / 100 g)比联结膜中的海藻糖含量(0.5 g / 100 g)高4倍以上。子实体中腺苷含量(0.024 g / 100 g)比联结法高3-4倍,而肌苷,胞嘧啶,鸟苷和尿苷(0.093、0.145、0.053和0.073 g / 100 g)在联结法中最高。菌丝体中的Cu和Se含量(3.30×10⁻⁴和3.1×10/100 g / 100 g)低于联结膜(1.85×10⁻³和7.2×10⁻⁵g / 100 g)和子实体(1.67× 10⁻³和4.3×10⁻⁵g / 100 g)。菌丝体中的砷,汞,镉和铅均在食用菌卫生标准的限制范围内。未发现Pb,但在子实体中检测到了Cd,Hg和As。这些发现表明,长曲霉可以根据市场需求以不同的培养方法加以利用,并且可能是健康食品或药用资源。
