火龍果花期集中在每年5-11月份，開花可達(dá)15次之多，花的產(chǎn)量大。在溫度適宜的條件下，火龍果植株自莖節(jié)處長出花苞，40-50天后夜間開放�；瘕埞ǔ使軤�，長約20厘米，花瓣寬闊，顯白色，也有少數(shù)為紅色[8]�；瘕埞崃康�，含有維生素C，蛋白質(zhì)、粗纖維、粗脂肪等營養(yǎng)成分以及豐富的礦質(zhì)元素,用作茶飲清涼解毒、滋陰潤肺[9-10]。此外，火龍果花還具有明目、降火的功效和預(yù)防高血壓的作用,可用于治療咳嗽、氣喘，此外火龍果花對(duì)肺結(jié)核、支氣管炎、頸部淋巴結(jié)核的治療有一定的輔助作用[11-13]。
目前，對(duì)火龍果花的關(guān)注多集中在火龍果花保健飲料研制、干制工藝及營養(yǎng)成分分析，而尚無對(duì)其抗氧化活性的進(jìn)行研究[14]�？寡趸镔|(zhì)的抗氧化能力，與其所具有的還原過氧化物的還原能力，使自由基不活性化及捕捉金屬離子等能力密切相關(guān)。利用自由基使顯色劑發(fā)生顏色變化,根據(jù)吸光度的變化值而間接測(cè)得自由基的含量是分光光度法的基本原理,本文通過測(cè)定火龍果花不同溶劑提取物對(duì)DPPH自由基、羥基自由基(•OH)、超氧陰離子自由基(•O2-)的清除作用及其還原能力，研究火龍果花提取物的抗氧化活性，同時(shí)與人工合成抗氧化劑BHT的抗氧化活性進(jìn)行了對(duì)比。以期為火龍果花的綜合開發(fā)和合理利用提供理論依據(jù)。

Flowering of Pitaya is concentrated in 5-11 months per year, which is up to 15 times with large output. The director of the dragon fruit plant buds emerges after 40 - 50 days in the night under suitable temperature conditions. Pitaya flowers are of tubular and about 20 cm wide with mainly white and a few red petals [8]. Pitaya flowers are low in calories and contain vitamin C, protein, crude fiber, crude fat and other nutrients as well as a wealth of mineral elements. They can be used as detoxification tea that is good for Yin and lungs [9-10]. In addition, the dragon fruit flower is also good for eyesight, and it could reduce pathogenic fire and prevention of hypertension. Besides, it can be used to treat cough, asthma, and the dragon fruit flower role could be in support of curing tuberculosis, bronchitis, the treatment of cervical lymph nodes [11-13].
At present, more attention has been paid to the development of dragon fruit juice for health, dried process and nutritional analysis. However, seldom research has been carried out yet on its antioxidant activity [14]. The antioxidant capacity and ability to restore the reduction of peroxide are closely related with inactive free radicals and the ability to capture metal ions. Free radical reagent can make the color change. The content of free radicals could be measured indirectly according to the changes in absorbance values which is the basic principle of spectrophotometry. By measuring the scavenging and reducing power and antioxidant activity different extracts from dragon fruit flowers on DPPH radical, hydroxyl free base (.OH), superoxide anion radical (.O2-), the activity of such extracts was investigated and a comparison has been made with the synthetic antioxidant BHT antioxidant. This will provide some theoretical basis for the comprehensive development and rational utilization of dragon fruit flowers.
