摘要
研究了两个采收期大叶灯笼精油含量和化学成分的季节变化，并分析了其对蛇足单胞菌的杀锥虫活性。雨季挥发油含量为0.13 ~ 0.29%，旱季挥发油含量为0.13 ~ 0.33%。化合物e -石竹烯、α-葎草烯、α-姜黄烯和革蕊烯D定义了在雨季和旱季形成的4个化学簇，分为:簇1 (e -石竹烯+革蕊烯D);簇2 (germacrene D + e -石竹烯);簇3 (α-葎草烯+ e -石竹烯);簇4 (α-姜黄烯+ e -石竹烯)。4个化学聚类的樟子树精油均具有较低浓度的抑制作用，其ic50值为:18.34±6.60 μg/mL (LAC-018，聚类1);9.14±3.87 μg/mL (LAC-027, Cluster 2);14.56±3.40 μg/mL (LAC-037, Cluster 3);14.97±2.68 μg/mL (LAC-019, Cluster 4)。
Seasonal variance in the chemical composition of essential oils from Lantana camaraaccessions and their trypanocidal activity on Phytomonas serpens
The objective of this study was to investigate the seasonal variance of the content and chemical composition of the essential oil from Lantana camaraaccessions at two harvest times, and to analyze the trypanocidal activity on Phytomonas serpens. Essential oil content ranged from 0.13 to 0.29% in the rainy season and from 0.13 to 0.33% in the dryseason. The compounds E-caryophyllene, α-humulene, α-curcumene and germacrene D defined the formation of four chemical clusters in the rainy and dry seasons, classified as: Cluster 1 (E-caryophyllene + germacrene D); Cluster 2 (germacrene D + E-caryophyllene); Cluster 3 (α-humulene + E-caryophyllene); and Cluster 4 (α-curcumene + E-caryophyllene). All L. camaraessential oils, representing the four chemical clusters, inhibited P. serpenswith low concentrations, considering the following IC50values: 18.34±6.60 μg/mL (LAC-018, Cluster 1); 9.14±3.87 μg/mL (LAC-027, Cluster 2); 14.56±3.40 μg/mL (LAC-037, Cluster 3); and 14.97±2.68 μg/mL (LAC-019, Cluster 4).
期刊介绍：
The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
