Microwave-assisted extraction of polysaccharides from Camptotheca acuminate (CAPs) was optimized by response surface methodology. The optimal parameters were as follows: microwave power, 600 W; liquid-solid ratio, 40:1 g/mL; extraction time, 14 min; and extraction temperature, 70 °C. Under these conditions, the yield of CAPs reached up to 8.61%. CAP-3, an acidic polysaccharide with a molecular weight of 121.34 kDa, was separated and purified from CAPs, which was only composed of glucose and mannose. CAP-3 exhibited strong antioxidant activity against DPPH (
0.78 mg/mL), hydroxyl radicals (
0.84 mg/mL) and also showed synergistic antioxidative effect with ascorbic acid in vitro. Meanwhile, CAP-3 could protect plasmid DNA from oxidative damage. Moreover, CAP-3 could improve immunomodulatory activity of RAW264.7 cells through promoting the phagocytosis and nitric oxide release. Therefore, CAP-3 had a strong potential in functional food, pharmaceuticals and cosmetics industries.

Use of various chemical separation and extraction methods, such as SOLID PHASE EXTRACTION; CHROMATOGRAPHY; and SUPERCRITICAL FLUID EXTRACTION; to prepare samples for analytical measurement of components.
The selective extraction of deciduous teeth during the stage of mixed dentition in accordance with the shedding and eruption of the teeth. It is done over an extended period to allow autonomous adjustment to relieve crowding of the dental arches during the eruption of the lateral incisors, canines, and premolars, eventually involving the extraction of the first premolar teeth.

Vaccines or candidate vaccines containing antigenic polysaccharides from Haemophilus influenzae and designed to prevent infection. The vaccine can contain the polysaccharides alone or more frequently polysaccharides conjugated to carrier molecules. It is also seen as a combined vaccine with diphtheria-tetanus-pertussis vaccine.
