Lantana rhodesiensis Moldenke is a plant native to subtropical and tropical regions, which is widely used in traditional medicine. The composition of essential oils hydrodistillated from leaves, fruits and stems of plants growing in two different localities of Côte d’Ivoire, Kapélé and Nyanbélégé, were analysed over four months. Essential oil composition was determined by gas chromatography–mass spectrometry (GC–MS), and the main constituents of leaf essential oils were β-caryophyllene (20.3–27.1%), α-copaene (9.5–11.9%), δ-cadinene (7.3–9.9%) and α-humulene (7.5–9.6%). Thymol was also found in two samples from Kapélé (7.7 and 13.4%) and in one sample from Nyanbélégé (17.4%). Fruit essential oil was characterised by a predominance of β-caryophyllene (22.8–25.2%), α-copaene (8.7–11.7%), α-humulene (8.0–9.9%) and δ-cadinene (7.3–10.6%). In addition, stem oil was dominated by β-caryophyllene (14.3–22.4%), followed by α-copaene (7.4–14.7%), δ-cadinene (10.6–12.6%), α-humulene (5.0–8.0%) and caryophyllene oxide (5.2–8.0%). Statistical analysis showed that leaf and fruit essential oils exhibited very similar compositions, but differed from those of the stem. Essential oils of the leaves showed antioxidant and anti-inflammatory activities. Samples with a high thymol concentration exhibited high antioxidant activities, while those containing low quantities of thymol displayed elevated anti-inflammatory properties.

科特迪瓦的一种新的化学成分马鞭草罗丹纳德·摩尔登克精油:化学成分和生物活性
马ode丹摩尔登克(Moldenke)是亚热带和热带地区的原生植物,在传统医学中被广泛使用。经过四个月的分析,从科特迪瓦两个不同地区的植物,叶子和果实的茎,果实和茎中经水蒸馏得到的精油的成分进行了分析。通过气相色谱-质谱法(GC-MS)确定香精油的成分,叶香精油的主要成分为β-石竹烯(20.3–27.1%),α-古柏烯(9.5–11.9%),δ-卡丹烯( 7.3–9.9%)和α-humulene(7.5–9.6%)。在来自Kapélé的两个样本(7.7%和13.4%)和来自Nyanbélégé的一个样本(17.4%)中也发现了百里香酚。水果精油的特征是主要以β-石竹烯(22.8–25.2%),α-可可烯(8.7–11.7%),α-腐植烯(8.0–9.9%)和δ-cad烯(7.3–10.6%)为特征。此外,干油中以β-石竹烯(14.3–22.4%)为主导,其次是α-可卡因(7.4–14.7%),δ-卡丁烯(10.6–12.6%),α-腐殖烯(5.0–8.0%)和石竹烯氧化物( 5.2–8.0%)。统计分析表明,叶和果精油的成分非常相似,但与茎的成分不同。叶子的精油显示抗氧化和抗炎活性。百里酚浓度高的样品表现出较高的抗氧化活性,而百里酚含量低的样品则具有较高的抗炎特性。叶子的精油显示抗氧化和抗炎活性。百里酚浓度高的样品表现出较高的抗氧化活性,而百里酚含量低的样品则具有较高的抗炎特性。叶子的精油显示抗氧化和抗炎活性。百里酚浓度高的样品表现出较高的抗氧化活性,而百里酚含量低的样品则具有较高的抗炎特性。
