Abstract

In this study, we examined Salvia amplexicaulis Lam., S. jurisicii Košanin and S. ringens Sibth. & Sm. collected in the Republic of North Macedonia, which are for the first time subjected to detailed micromorphological and structural analysis using light and scanning electron microscopy. The nutlets and mucilage were additionally subjected to spectroscopic analysis using Raman and Attenuated Total Reflectance Fourier Transform Infrared spectroscopy. The anatomical structure of stems and leaves is described and compared. The stems, leaves and calyces bear numerous one- and multi-cellular nonglandular trichomes, and various peltate, capitate and digitiform glandular trichomes. The nutlets differ in size and shape, as well as in myxocarpy. The nutlets predominantly contained α-linolenic and linoleic acid, whereas the mucilages are primarily formed of polysaccharides. The results obtained in this study confirmed the importance of micromorphological and anatomical analysis of Salvia L. spp. plant parts, particularly trichomes and nutlets, and hence contributing to the knowledge about the variety of micromorphological characteristics within the genus Salvia L.

摘要

在这项研究中，我们研究了丹参抱茎林，S. jurisicii Košanin和S. ringens西伯斯 ＆Sm。在北马其顿共和国收集的，这是第一次使用光和扫描电子显微镜进行详细的微观形态和结构分析。使用拉曼光谱和衰减全反射傅立叶变换红外光谱对坚果和粘液进行光谱分析。描述并比较了茎和叶的解剖结构。茎，叶和花萼带有许多单细胞和多细胞的非腺毛，以及各种齿状，头状和指状腺毛。小坚果的大小和形状以及my果不同。小坚果主要包含α-亚麻酸和亚油酸，而粘液主要由多糖形成。丹参L.属。植物部分，尤其是毛状体和小坚果，因此有助于了解丹参属微形态特征的多样性。
