TLDR
Four diterpenoids, carnosic acid, carnOSol, rosmanol, and epirosmanol were isolated as antioxidative agents from the leaves of Rosmarinus officinalis and were shown to be effective to protect biological systems against oxidative stresses.Abstract:
Four diterpenoids, carnosic acid (1), carnosol (2), rosmanol (3), and epirosmanol (4), were isolated as antioxidative agents from the leaves of Rosmarinus officinalis by bioassay-directed fractionation. These diterpenoids inhibited superoxide anion production in the xanthine/xanthine oxidase system. Mitochondrial and microsomal lipid peroxidation induced by NADH or NADPH oxidation were also completely inhibited by these diterpenes at the concentration of 3-30 microM. Furthermore, carnosic acid protected red cells against oxidative hemolysis. These phenolic diterpenes were shown to be effective to protect biological systems against oxidative stresses.read more

Health-promoting properties of common herbs
TL;DR: The volatile essential oils of commonly used culinary herbs, spices, and herbal teas inhibit mevalonate synthesis and thereby suppress cholesterol synthesis and tumor growth.

Antioxidant activities of some extracts of Thymus zygis
TL;DR: There is a relationship between antioxidant potency and the total phenolic groups content in each extract, and Methanolic extracts are more potent as scavengers of peroxyl and superoxide radicals than the ethyl ether extracts.

Changes in carotenoids, tocopherols and diterpenes during drought and recovery, and the biological significance of chlorophyll loss in Rosmarinus officinalis plants.

TL;DR: The photoprotection conferred by the xanthophyll cycle and the antioxidant function of tocopherols, lutein and diterpenes may help to avoid irreversible damage in severe drought, making possible the recovery of functional membranes after the autumn rainfalls.

TL;DR: Results indicate high selectivity of the subcritical water toward the most active compounds of rosemary such as carnosol, rosmanol, carnosic acid, methyl carnosate, and some flavonoids such as cirsimaritin and genkwanin.
