In vitro antioxidant and photoprotective activity of five native Brazilian bamboo species
Abstract
Nature provides an abundant source of antioxidant substances as well as potential compounds for sunscreen products. Asian bamboos, well known and widely cultivated, are already used in cosmetic and pharmaceutical industries thanks to their rich phenolic contents which is related to their antioxidant activity. This study aimed to evaluate the photoprotective and antioxidant activities of five native Brazilian bamboo species. Firstly, hydroalcoholic extracts from culms and leaves of Aulonemia aristulata (Döll) McClure., Chusquea bambusoides Rupr. ex Döll, Chusquea capituliflora Trin. var. pubescens McClure, Chusquea meyeriana Rupr., Merostachys pluriflora Munro ex E.G. Camus were evaluated for their DPPH scavenging activity and total contents of flavonoids and phenolic compounds. Secondly, cosmetic formulations containing the extracts in a combination with three different synthetic ultraviolet (UV) filters (avobenzone, octyldimethyl PABA, and octyl methoxycinnamate) were developed to evaluate their Sun Protection Factor (SPF), critical wavelength (cλ) and photostability by diffuse transmittance analysis to determine the interactions involving the extracts and the anti-UV active ingredients. The bamboos’ antioxidant potential, expressed in IC₅₀, varied between 137.55 and 260 μg/mL. Phenolic contents ranged from 43.64 to 87.81 mg of gallic acid equivalents (GAE) per g of plant material. The extract richest in flavonoids was that from C. bambusoides leaves with 6.44 mg of equivale…

Extracts of Lippia sericea, Cecropia obtusa, Acacia catechu, Brazilian bamboo, and Lasallia pustulata have high SPF values in formulations (SPF = 7-86), with Brazilian bamboo most promising at SPF 44 after irradiation.
“The other extracts revealed to possess a complex mixture of compounds, namely a high content of phenols [102,105] and polyphenols [103] and high SPF values in formulations (SPF = 7–86) [102,103,104,105,106], being the extract of Brazilian bamboo species the most promising with a SPF value of 44, after irradiation [105].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
