Unravelling the Photoprotection Properties of Garden Cress Sprout Extract

Abstract

Plants, as with humans, require photoprotection against the potentially damaging effects of overexposure to ultraviolet (UV) radiation. Previously, sinapoyl malate (SM) was identified as the photoprotective agent in thale cress. Here, we seek to identify the photoprotective agent in a similar plant, garden cress, which is currently used in the skincare product Detoxophane nc. To achieve this, we explore the photodynamics of both the garden cress sprout extract and Detoxophane nc with femtosecond transient electronic absorption spectroscopy. With the assistance of liquid chromatography-mass spectrometry, we determine that the main UV-absorbing compound in garden cress sprout extract is SM. Importantly, our studies reveal that the photoprotection properties of the SM in the garden cress sprout extract present in Detoxophane nc are not compromised by the formulation environment. The result suggests that Detoxophane nc containing the garden cress sprout extract may offer additional photoprotection to the end user in the form of a UV filter booster.

“…We now assign dynamical processes to the extracted time constants reported in Table 5, and discuss their implications drawing on previous studies on SM. 12,92–95 The similarity between the information extracted from SM and its derivatives in the current work is an indication that the relaxation mechanism likely remains largely unchanged upon the addition of a long chain fatty acid. Hence, we assign the dynamical processes to the extracted time constants as a collective.…”

“…in their characterization of formulations enriched with Camellia sinensis tea extract, state that there are flavonoids such as thearubigins (TRs), theaflavins (TFs), and theobrownins (TBs), among others, assessed in the same methodology [25,[36][37][38]. Andrade et al [39] valuated the hydroalcoholic extract of Bordeaux grape pomace, observing that this extract achieved an SPF of 12.…”
