This study was to compare the total phenolic (TP) content in extracts from eleven plant materials collected at different geographical locations in Kenya, Nigeria, and USA. These plants have been selected because the majority of them are highly pigmented, from yellow to purple, and would therefore have economic value in industries for producing antioxidants and surfactants. Two of them were collected from the industrial and domestic waste outlets. Each analysis was achieved using the Folin-Ciocalteau technique. The order of decreasing phenolic acid content as gallic acid concentration (mg/g dry weight) was Prunus africana (55.14) > Acacia tortilis (42.11) > Khaya grandifoliola (17.54) > Curcuma longa (17.23) > Vernonia amygdalina (14.9)> Russelia equisetiformis (14.03) > Calendula officinalis (7.96) >Phragmites australis (control) (7.09) > Rauwolfia vomitoria (6.69) > Phragmites australis (industrial) (6.21) > Cnidoscolus aconitifolius (5.6). The TP contents of Spartina alterniflora species were below the detection limit.
本研究旨在比较从肯尼亚、尼日利亚和美国不同地理位置采集的11种植物材料提取物中的总酚（TP）含量。选择这些植物是因为它们中的大多数颜色从黄色到紫色，色素含量高，因此在生产抗氧化剂和表面活性剂的行业中具有经济价值。其中两种植物是从工业和家庭垃圾排放口采集的。每次分析均采用福林-西奥尔特法。以没食子酸浓度（毫克/克干重）表示的酚酸含量从高到低的顺序为：非洲李（55.14）＞阿拉伯胶树（42.11）＞大叶桃花心木（17.54）＞姜黄（17.23）＞扁桃斑鸠菊（14.9）＞串叶松香草（14.03）＞金盏花（7.96）＞芦苇（对照）（7.09）＞催吐萝芙木（6.69）＞芦苇（工业用）（6.21）＞刺萼龙葵（5.6）。互花米草的TP含量低于检测限。
