Study on Ultrasonic Extraction of Total Saponin from Hylocereus undatus;

Planting and Machining Technics of Hylocereus undatus;

Hylocereus undatus, a typical flower of province Guangdong, was loved bypeople of province Guangdong.

It demands foil fencers having very good ability in controlling the point of blade because the effective area is very small according to the rule.

The study examined influential factors of foil fencers decision-making in simulating fencing situation.

Aim: Correctly measure and evaluate the anaerobic performance of elite foilsmen so as towork out programs for physical ability training.

Using rutin as the standard sample, the flavonoids substances in sisal flower were determined through methyl alcohol ultrasonic extraction and ultraviolet spectrophotometer.

In this study, petroleum ether-phase, ethyl acetate-phase and n-butanol-phase fractions of ethanol extract of sisal flower and polysaccharides extracted from the ethanol extraction residue were prepared and then their antioxidant activities were evaluated by measuring the scavenging rates to DPPH radical (DPPH·), hydroxyl radical (·OH) and superoxide anion radical (O-2·) respectively .

By the ways of documentation,expert interview,statistics and experiment,and applying the relative theories of sports training and sports physiology,training,test and analysis were arranged on the choice reaction time of Shanghai amateur women foil fencers.

The technique statistic analysis based on the male fleuret competition of the 9th game in 2001, showed that the swing puncture had important status and effect in the fleuret competition.
