A cultivar of fruiting bodies of Ophiocordyceps sinensis (FBOS; OCS02) was analyzed for nutrients, bioactive compounds, and heavy metal content to showcase its potential as a competitive, sustainable, and safe alternative to wild types and other cultivars. A previous 28-day subacute toxicity study showed that doses up to 1 g · kg-1 did not cause any adverse effects in Sprague-Dawley rats. The OCS02 cultivar contained large amounts of cordycepin, polysaccharides, and essential and semi-essential amino acids (0.66, 482.80, 99.02, and 101.04 g · kg-1, respectively) compared with levels reported in wild types and in cultivated mycelia. β-1,3/1,6-glucan content was considerably high at 342.50 g · kg-1. The potassium level (5.14 g kg-1) tied in well with the low sodium content (0.121 g · kg-1)-6 times lower than amounts in wild types. We found no detectable levels of heavy metals such as lead, arsenic, cadmium, and mercury. The major amino acids found in FBOS (0CS02 cultivar) were arginine, lysine, serine, and threonine at 45.20, 20.30, 18.60, and 18.20 g · kg-1, respectively. The cultivated FBOS (OCS02 cultivar) is a comparable alternative to wild-type and other cultivated strains of O. sinensis. It has potential as a nutraceutical to meet market demand.

:分析了中华phi的子实体(FBOS; OCS02)的营养成分,生物活性化合物和重金属含量,以展示其作为野生型和其他品种的竞争性,可持续性和安全性替代品的潜力。先前的28天亚急性毒性研究表明,高达1 g·kg-1的剂量不会对Sprague-Dawley大鼠造成任何不良影响。与野生型和栽培菌丝体中报道的水平相比,OCS02品种包含大量的虫草素,多糖以及必需和半必需氨基酸(分别为0.66、482.80、99.02和101.04 g·kg-1)。 β-1,3/ 1,6-葡聚糖的含量很高,为342.50 g·kg-1。钾水平(5.14 g kg-1)与低钠含量(0.121 g·kg-1)-6倍相关,比野生型低。我们没有发现可检测水平的重金属,例如铅,砷,镉和汞。 FBOS(0CS02品种)中发现的主要氨基酸分别为精氨酸,赖氨酸,丝氨酸和苏氨酸,分别为45.20、20.30、18.60和18.20 g·kg-1。栽培的FBOS(OCS02品种)是野生型和其他栽培稻的可比替代品。它具有满足市场需求的营养保健品的潜力。
