主要营养成分及药用成分测定结果表明：原木灵芝菌柄的粗蛋白、粗脂肪及氨基酸含量虽然较菌盖低，但含有０．９８％多糖、０．１２ｍｇ／ｇ三萜酸（灵芝酸Ａ、Ｂ、Ｃ），具有较高的药用价值；此外，菌柄必需氨基酸所含比例较高（Ｅ／Ｔ＝０．６５９）。因此，菌柄可以用于浸膏粉生产。提取试验结果表明：菌柄提取率为２．０３％～２．０６％，菌盖Ｃ级品达３．６４％～３．７６％，Ｂ级品达４．６５％～４．８５％；由不同原料生产的灵芝浸膏及浸膏粉的主要成分含量差异较大。按Ｂ级品＋３０％菌柄或Ｃ级品＋２０％菌柄投料，可以使浸膏提取率分别控制在３．０２％～３．１２％及３．９２％～４．０３％。采用这两种合理投料组成，生产出来的浸膏粉质量相当稳定，主要成分含量变化不大，从而实现对成品质量的有效控制。产品送检日本分析，质量合乎要求，其中多糖含量还高于日本同类产品。
The results showed that the crude protein, crude fat and amino acid contents of the fungi of Gentiana macrophylla contained 0.98% polysaccharide, 0.12mg / g triterpene acid (Ganoderma acid A , B, C), which has high medicinal value. In addition, the ratio of essential amino acids in the stipe is higher (E / T = 0.659). Therefore, the stipe can be used for extract powder production. The results of extraction showed that the extraction rates were 2.03% ~ 2.06%, the contents of capped C grade were 3.64% -3.76%, and those of B grade were 4.65% -485%. The main ingredients of Ganoderma lucidum extract and extract powder produced by different raw materials vary greatly. By B grade + 30% stipe or C grade + 20% stipe feeding, can make extract rate were controlled at 3.02% ~ 3.12% and 3.92% ~ 4.03%. Adopt the two kinds of reasonable feeding composition, the quality of the extract powder produced is quite stable, the content of the main components does not change much, so as to realize the effective control of the finished product quality. Product inspection Japan analysis, the quality requirements, including polysaccharide content is also higher than similar products in Japan.
