Content Determination of Polysaccharides of Ganderma lucidum in Spore Powder Capsule by HPLC
Abstract: ObjectiveTo establish an HPLC method for determination of Ganoderma lucidum
Polysaccharide in spore powder capsule. MethodsA Shodex SH1011 column was used with 0.6% sulphuric acid solution. The detection wavelength was set at 200nm.ResultsThe linear relationship of the concentrations and peak areas was good in range of 0.266 ~ 8.51 mg /
ml (r = 0.999 8). The average recovery was 100.4% (n = 9), RSD = 1.57%. ConclusionThe method is simple, rapid and accurate and can be used for quality control of the capsule.
Key words: Spore powder of Ganderma lucidum ganderma capsule; Polysaccharides; HPLC
Ganoderma lucidum spore powder capsule from the Ganoderma spore powder capsule [WS
5026 (B 0026) 2004] to change formulations made with spleen Qi, Yang Anshen effect. For the Heart and deficiency, sickness and infirmity, as well as cancer patients after adjuvant treatment. The effective ingredients of Ganoderma lucidum polysaccharides, triterpenoids, with its polysaccharide content of about 0.75% . Determination of polysaccharide used sulfuric acid - anthrone  and sulfuric acid phenol
spectrophotometric method [3,4]. The method error larger, more complicated operations. Determination of polysaccharide content using HPLC [5,6] have reported that Ganoderma
lucidum spore powder formulations using high performance liquid chromatography
polysaccharide not been reported. This selection of high-performance liquid chromatography
method for the fungus Ganoderma lucidum spore powder soft capsules in the Determination of polysaccharide in the establishment of a high separation efficiency, good stability, rapid analysis method for controlling quality of preparation provided a reliable method. The study methodology, in line with requirements determination.

2 Methods and Results
2.1 Chromatographic conditions
Column: ShodexSH1011 (styrene-divinylbenzene copolymer bonded sulfonic) (8.0 mm ×
300 mm, 6 μm), mobile phase: sulfuric acid water (6:1 000), detection wavelength 200
nm, flow rate 0.6 ml / min, injection volume of 20 μl, column temperature 30 ?. In the
above-mentioned chromatographic conditions, D anhydrous glucose retention time of 4.987
2.2 The product solution and reference substance for the test preparation solution
This product is 10 to take the contents mixed evenly, taking about 3.0 g, precision that will placed in 10 ml glass centrifuge tube, add n-hexane 8 ml, shock 2 min after
centrifugation (3000 r / min) 10 min, discard to n-hexane layer, and then repeat the above
steps once, water bath to shake off residual n-hexane, it will transfer them to the 10 ml
flask, add the appropriate amount of water, 100 ? water bath 1 h, lack of water, mixing,
filtration, take filtrate 2.0 ml by adding ethanol 8.0 ml, shake and place 2 min after centrifugation (3 000 r / min) 10 min, supernatant and sediment dissolved with 2.0 ml mobile phase, 1 h after 100 ? water bath that is too . Separate examination of the hydrolysis time. The results in Table 1. Examination of hydrolysis time in Table 1 (omitted)
The results can be completely hydrolyzed more than 1h, so choose 1h as the hydrolysis point in time.
Precision said the scheduled 48 h vacuum drying of the D anhydrous glucose
reference substance 21.28 mg, buy 10 ml flask, add the mobile phase was dissolved and diluted to the scale, shake, made with D per ml anhydrous glucose 2.128 mg of the
solution, filtration, that is, too.
Adaptability of the system, an experimental study. The results in Table 2. Table 2 Experimental results of system suitability study (omitted)
