The subchronic toxicity of octyl acetate was assessed following its administration to rats via oral gavage, 5 days per week for 13 weeks. Treated rats received undiluted octyl acetate at doses of 0.1, 0.5, or 1.0 g/kg. Control rats received distilled water at a dose of 1.0 g/kg. An interim termination was made after 45 days of dosing at which time five animals per sex per group were terminated and necropsied. Blood samples were collected and liver tissues were prepared for histological examination. After 13 weeks of dosing all animals were terminated and necropsied. Blood samples were obtained and selected organs were weighed and prepared for subsequent histological examination. Several treatment-related effects were observed in the high-dose group (1.0 g/kg) animals. These effects included slight reductions in body weight and food consumption, increased liver and kidney weights, and evidence of hydrocarbon nephropathy in high-dose males only. The significance of these observations is discussed in the report. With the exception of increased liver weights in the mid-dose group, no other significant treatment-related effects were observed in the mid- or low-dose groups of animals. It is believed that the increases in liver weight which were observed are a compensatory response to an increased metabolic load, and not a reflection of true hepatotoxicity. The results of this study indicated that octyl acetate possessed an overall low degree of systemic toxicity when administered orally to rats for 13 weeks.

The aliphatic esters octyl acetate and octyl butyrate occur as major components of essential oils in the vittae, or oil tubes, of the wild parsnip (Pastinaca sativa). We determined phenotypic variation and narrow-sense heritabilities of these octyl esters in wild parsnip fruits from 30 maternal families. The mean octyl acetate content was 1.56 microg/mg dry fruit (0.08-5.51 microg/mg dry fruit) and the mean octyl butyrate content was 4.28 microg/mg dry fruit (1.28-14.22 microg/ mg dry fruit). Narrow-sense heritabilities for each ester’s content were calculated by analysis of half-sib families (HS) and parent-offspring regression (OP). Heritabilities were 0.389 (HS) and 0.654 (OP) for octyl acetate and 0.670 (HS) and 0.626 (OP) for octyl butyrate. The amounts of the esters were phenotypically correlated with each other and with the linear furanocoumarins bergapten and xanthotoxin, phototoxic compounds that co-occur in the vittae with the esters. Ester amounts were not genetically correlated, indicating that these compounds could respond independently to selection pressures. These octyl esters may serve as carrier solvents that enhance penetration of these furanocoumarins into herbivore integuments and gut walls.

The essential oil obtained from the fruits of hogweed (Heracleum sphondylium subsp. ternatum) growing in central Apennines (Italy) was analysed for chemical composition by gas chromatographic-flame ionisation detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The oil was composed mainly of aliphatic esters (86.9-89.5%), among them octyl acetate (54.9-60.2%) and octyl butyrate (10.1-13.4%) were the most abundant. The oil and its two major esters, octyl acetate and octyl butyrate, were tested for in vitro biological activity, namely antibacterial, antioxidant and cytotoxic, by microdilution, DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)) and MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assays. Worthy of mention was only the cytotoxic activity of the oil against two tumour cell lines, i.e. A375 (human malignant melanoma) and HCT116 (human colon carcinoma) cells, with IC50 values of 48.69 and 95.83 μg/mL, respectively; the major compound responsible for this effect was octyl butyrate which displayed IC50 values of 20.19 μg/mL (100.8 μM) and 55.35 μg/mL (276.3 μM) on the same cells, respectively.
