Extraction and Phytochemical Analysis of Anthemis susiana Nabelek Using Headspace-solid Phase (HS-SPME) and Gas Chromatography-mass Spectrometry (GC-MS)

Chamomile has several variants, such as Anthemis Susiana Nabelek, Matricaria chamomilla L., Chamomilla recutita (L.) Rauschert, Matricaria suaveolens Koch and etc. Medicinal herbs, extracts and essential oils are of particular importance in the pharmaceutical, cosmetic and food industries. The phytoanalysis of these compounds is of particular importance. In April 2019, Anthemis Susiana Nabelek samples were collected from the Thermal Springs area of Dehloran, south of Ilam province, western Iran. The plant was dried and then pulverized. The essential oil was extracted from the plant using HS-SPME and analyzed using GC-MS. GC-MS results showed that Anthemis susiana Nabelek contains 63 chemical compounds. The main chemical compounds included alpha-bisabolol oxide A (19.07), alpha-pinene (15.50), beta-bisabolene (12.56), spathulenol (9.23), beta-farnesen (8.95), alpha-bisabolol (4.72), caryophyllene oxide (4.46), trans-farnesol (3.75), and dl-limonene (3.47)

Bismuth‐melt trails trapped in cassiterite–quartz veins

Native bismuth in the form of metallic melt has been considered instrumental to the formation of some metallic ore deposits via a mechanism dubbed the ?Liquid Bismuth Collector Model.? Here, we provide petrographical documentation of trail?forming, ?m?sized blebs of native bismuth in cassiterite?quartz veins from the Santa B?rbara greisen Sn deposit in the Rond?nia tin province of northern Brazil. These inclusions suggest the trapping of a Bi melt that took place during vein formation, in a mecha? nism similar to the entrapment of fluid inclusions
