Influence of Light on Essential Oil Constituents
K. Hüsnü Can Başer, Gerhard Buchbauer in Handbook of Essential Oils, 2020
Li et al. (2016) investigated the transformations occurring during UV and air exposure in the EO of white guanxi honey pummelo (Citrus grandis (L.) Osbeck, Rutaceae), which is a citrus variety from Southeast Asia. The main constituents of pummelo are (+)-limonene and β-myrcene, germacrene D, geranial, neral, β-pinene, linalool, sabinene, and α-pinene (Sun et al., 2014). The EO was mechanically pressed from the fruit, and one sample was irradiated with UV light for 40 h while being exposed to air at approximately 25°C. In order to identify degradation mechanisms, single standard aldehydes without solvent dilution—that is, octanal (99%), nonanal (96%), citronellal (96%), decanal (95%), citral (97%, mixture of trans-citral and cis-citral), perilla aldehyde (92%), dodecanal (95%), and dodecenal (93%)—were subjected to air exposure, UV irradiation, or a combination of both (Li et al., 2016).

The phytochemical profile of D. anethifolia has only been partly explored. In the literature, the majority of papers deal with the composition of the essential oil (EO). As major constituents, α-pinene (11.6% (Mostafavi et al. 2008), 70.3% (Mottaghipisheh et al. 2014), 59.2% (Janssen et al. 1984)); n-decanal (1.4-45% (Karami and Bohlooli 2017), 45.06% (Vazirzadeh et al. 2017), 70% (Hajhashemi et al. 2010), 57% (Mahboubi and Feizabadi 2009), 25.6–30.3% (Mazloomifar and Valian 2015), 18.8% (Sefidkon and Javidtash 2002)), dodecanal (28.8% (Shahabipour et al. 2013)), cis-chrysanthenyl acetate (72.28%) (Ashraf et al. 1979; Habibi et al. 2017) have been reported.

Terpenoids, aldehydes and ketones were all found in higher abundances in the tuber extract in comparison to the leaf formulation. Limonene, octanal, nonanal and acetophenones had much higher relative abundances in the tuber extract and eucalyptol**, decanal, dodecanal and fatty alcohols (octanol and dodecanol) were found only in this plant preparation. The only class of compounds that was found in higher percentages in the leaf extract was the class of esters, with butyl acetate being accountable for 53.7% of the total volatile constituents in this S. chacoense preparation (Table 4).
