翼手龙（Pterodon embryatus Vogel），豆科，是一种通常被称为“sucupira-branca”的树种。它是巴西塞拉多（稀树草原）的一种受欢迎的药用植物。本研究旨在探讨松果实挥发油的化学变异性。从巴西塞拉多的五个地点收集的水果和精油进行了GC/MS分析。通过主成分和聚类分析得到的结果确定了两个组：集群I含有β-香芹烯和δ-榄香烯和集群II含有α-copaene，β-cubebene，allo-aromadendrene，α-cubebene和γ-muurulene。典型判别分析用于区分基于精油组成的聚类。研究结果表明，甜茶果实精油成分具有高度的变异性，有助于该物种的驯化研究。
Pterodon emarginatus Vogel, Fabaceae, is a tree species commonly known as "sucupira-branca". It is a popular medicinal plant in the Brazilian cerrado (Savanna). This study investigates the chemical variability of the essential oils from fruits of P. emarginatus. The fruits were collected from five sites in the Brazilian Cerrado and their essential oils were analyzed by GC/MS. The results obtained by Principal Component and Cluster Analysis identified two groups: cluster I containing beta-caryophyllene and delta-elemene and cluster II containing alpha-copaene, beta-cubebene, allo-aromadendrene, alpha-cubebene and gamma-muurulene. The Canonical Discriminant Analysis was used to differentiate between clusters on the basis of essential oil composition. The results showed high variability in the composition of the essential oils from fruits of P. emarginatus, contributing to studies of domestication of this species.
