TLDR
The volatile oils of black pepper, clove, and thyme exhibited considerable inhibitory effects against all the organisms under test while their major components demonstrated various degrees of growth inhibition.Abstract:
The volatile oils of black pepper [Piper nigrum L. (Piperaceae)], clove [Syzygium aromaticum (L.) Merr. & Perry (Myrtaceae)], geranium [Pelargonium graveolens L'Herit (Geraniaceae)], nutmeg [Myristica fragrans Houtt. (Myristicaceae), oregano [Origanum vulgare ssp. hirtum (Link) Letsw. (Lamiaceae)] and thyme [Thymus vulgaris L. (Lamiaceae)] were assessed for antibacterial activity against 25 different genera of bacteria. These included animal and plant pathogens, food poisoning and spoilage bacteria. The volatile oils exhibited considerable inhibitory effects against all the organisms under test while their major components demonstrated various degrees of growth inhibition.read more

Antioxidant Capacity of 26 Spice Extracts and Characterization of Their Phenolic Constituents
TL;DR: This study provides direct comparative data on antioxidant capacity and total and individual phenolics contents of the 26 spice extracts and showed that phenolic compounds in the tested spices contributed significantly to their antioxidant capacity.

Use of phytogenic products as feed additives for swine and poultry.
TL;DR: The authors summarizes the experi- mental knowledge on efficacy, possible modes of action, and aspects of application of phytogenic products as feed additives for swine and poultry. But the assumption that phytogen compounds might prove the palatability of feed has not yet been confirmed by choice-feeding studies.
