Dragon’s Blood Sap: Storage Stability and Antioxidant Activity

Abstract

Currently, consumers are demanding additive-free, fresher, and more-natural products. Dragon’s Blood Sap (DBS), the deep red latex of the specie of tree Croton lechleri (Müll. Arg.), contains a high concentration of phenolic compounds of great interest for the food, pharmaceutical, and cosmetic industries. These chemical compounds are highly susceptible to degradation. Therefore, DBS storage stability and its photo-oxidation was studied by Fourier transform infrared spectroscopy (FT-IR) and UV-Vis spectrophotometry for 39 days at different temperatures (4–21 °C) and relative humidities (0–56%), as well as under UV light exposure. It was observed that the degradation of phenolic compounds was reduced at 0% relative humidity (RH), not showing a significant effect of temperature in the range studied. UV light irradiation degraded DBS in a 20%. DBS has an exceptional high and stable antioxidant content (≥93% inhibition percentage of DPPH), which makes it a unique property to consider the DBS as an antioxidant agent or ingredient for consumer products formulations.

Antibacterial and Anti-biofilm Efficacy of Chinese Dragon’s Blood Against Staphylococcus aureus Isolated From Infected Wounds

“…Proanthocyanidin, as a final product of the flavonoid biosynthetic pathway, is known to effectively prevent and cure bacterial infections (Rauf et al, 2019). Also, these phenolic compounds can be easily degraded (Escobar et al, 2018). As shown in Figure 2, S. aureus exhibited remarkably increased cell growth at all concentrations of CDB after treatment for 12 h, which is consistent with previous reports.…”

Especies con características funcionales y medicinales de la agrobiodiversidad de la Amazonia ecuatoriana

“…Los resultados de los estudios in vitro e in vivo respaldan en gran medida la mayoría de los usos etnomédicos de sangre de drago, incluido el tratamiento de diarrea, heridas, tumores, úlceras estomacales, infección por herpes, picazón, dolor e hinchazón de picaduras de insectos (Jones, 2003), además alberga una rica comunidad de hongos endofíticos con potencial antibacteriano, especialmente contra las bacterias Gram positivo (Vargas et al, 2018). El aceite de C. lechleri según (Rossi et al, 2011) puede utilizar como un nuevo ingrediente protector aromatizante para alimentos o suplementos dietéticos contra mutágenos, en este contexto (Escobar et al, 2018) coincide que C. lechleri contiene antioxidantes excepcionalmente alto y estable (≥ 93%), esta propiedad es indispensable para ser usado como un agente antioxidante o ingrediente para formulaciones de productos de consumo.…”

“…Due to their health benefits, the scientific community and the food, pharmaceutical, and cosmetic industries, among others, have paid special attention to the isolation of phenolic compounds from different raw materials, especially from inexpensive or residual sources such as medicinal plants, fruits, vegetables, industrial by-products, and beverages [ 9 ]. In this sense, dragon’s blood sap (DBS) obtained from the bark of Croton lechleri (Müll, Arg.)…”
