Phytosterols are nutritionally vital phytoconstituent owing to their cholesterol (low-density plasma lipoprotein-cholesterol, LDL-C)-lowering, anti-inflammatory, and antioxidant properties. Among the widely used spices and herbs, the seeds spices of the Apiaceae family represented the healthiest fatty acid profile. Thus, to explore the other health-beneficial lipids, the present study was aimed to analyze the phytosterol profile of eight seed spices of the Apiaceae family, utilizing gas chromatography (GC)-mass spectrometry (MS). The sterols contents calculated on an oil (mg/100 g of oil) and spice weight (mg/100 g spices; dry weight) basis varied significantly among the seed spices (p < 0.05; Turkey HSD). The β-sitosterol and stigmasterol were the most dominating sterols among the studied spices, together accounted for 40.3 (Ajwain) to 69.8% (celery) of total sterols in the seed oil. Among the studied spices, the oil extracted from caraway seeds showed the highest total sterols (602.2 mg/100 g of oil). Interestingly, based on spice weight, fennel seeds also showed the similar highest number of total sterols (134.2 mg/100 g in fennel and 133.3 mg/100 g in caraway), owing to the high contents of oil (25.9%) in fennel seeds. Overall, celery, caraway, fennel, and anise seeds oil are rich sources of health-beneficial phytosterols.

The caraway seed (Carum carvi L.) grown in Alberta was steam-distilled for its essential oil. During a 4-yr trial, the two harvests made gave a seed oil yield which averaged 2.65% calculated on a dry weight basis. The oil quality was assessed through analysis by combined TL- and GL-chromatography, and by mass and infrared spectrometry. There were 12 major constituents in the oil, with a corresponding percentage of 93.9%. D(+)-carvone and D(+)-limonene were not less than a total of 87.5% of the oil. There were 23 minor and at least 13 trace constituents. The low amount of benzene-related constituents in the oil was taken as a chemical proof for the correct botanical identity of the plants used in the trial. The oil composition was compared with oils which were imported and used by the domestic food industry. The data showed that the oil used by industry is 7% higher in carvone and 6% lower in limonene, while the other constituents are practically the same. The lower carvone content in Alberta oil was attributed to the fact that the climate of the Prairies permitted the seeds to only partly mature, rather than to an inherent carvone deficiency of the fruit.

This study examined the thermal and catalytic pyrolysis of waste Achyranthes Root (AR) using pyrolyzer-gas chromatography/mass spectrometry (Py-GC/MS). The non-catalytic pyrolysis of waste AR produced various kinds of oxygenates, such as acetic acid, hydroxy propanone, furfural, phenol, cresol, guaiacols, syringols, and so on. By applying nanoporous Al-MCM-41 with acidic properties and mesopores to the pyrolysis of waste AR, the levels of furan and aromatic hydrocarbons production increased with a concomitant decrease in the other oxygenates. The formation efficiency of furans was improved further by increasing the amount of Al-MCM-41 applied to the catalytic pyrolysis of waste AR.
