The total water-soluble polysaccharide (TP) of is composed of starch and active non-starch polysaccharides (NSPs) with glucomannan as the main structural type. Although the TP content has been used as a quality assessment indicator for many years, the NSPs content in samples from different environments and growth seasons have not been reported. In this study, we found that NSPs had stronger antioxidant activity than TP. The NSPs content was higher in wild-simulated environments including rocks and trees compared to plantings grown in greenhouse. The culture mode and growth period affected the ratio of NSPs and starch. Facility cultivation provided optimal growth conditions but produced more starch, whereas wild-simulated cultivation resulted in a higher ratio of NSPs, particularly in September. Therefore, cultivation by lithophytation and epiphytation may be preferable to facility plantings, which is expected to be enormously useful for the current production and quality control of . .
[具体物质名称]的总水溶性多糖（TP）由淀粉和以葡甘露聚糖为主要结构类型的活性非淀粉多糖（NSPs）组成。尽管多年来TP含量一直被用作质量评估指标，但不同环境和生长季节样品中的NSPs含量尚未见报道。在本研究中，我们发现NSPs的抗氧化活性比TP更强。与温室种植相比，在包括岩石和树木的仿野生环境中NSPs含量更高。培养方式和生长时期影响NSPs与淀粉的比例。设施栽培提供了最佳生长条件，但产生了更多淀粉，而仿野生栽培导致NSPs比例更高，尤其是在9月。因此，石上种植和附生种植可能比设施种植更可取，这有望对[具体物质名称]目前的生产和质量控制非常有用。
