Abstract
Dendrobium sulcatum Lindl or “Ueang Jampa-Nan” (Orchidaceae family) is widely dis-tributed in Thailand and Laos. It is classified in the genus Dendrobium, which is used in both traditional Chinese medicine and Ayurvedic medicine for health enhancement and anti-aging. The purpose of this study was to investigate the phytochemical constituents and bioefficacy of stems, leaves and flowers from D. sulcatum for cosmetic and cosmeceutical applications. Phenolic and flavonoid contents were tested for the phytochemical evaluation. The antioxidant (DPPH, FRAP and ABTS assays), anti-lipid peroxidation, antiglycation, anti-inflammatory and anti-tyrosinase properties were assessed for their bioefficacy. The results showed that the extracts of stem and leaf had higher total phenolic content than that of the flower, and the leaf extract had the highest flavonoid content. The antioxidant, anti-lipid peroxidation and anti-inflammatory activities of the extracts were greater in those from the stem and leaf compared with that of the flower. The leaf extract exhibited the greatest antiglycation property. The results of anti-tyrosinase analysis of the extracts showed that the leaf and flower exhibited potent activities with a percentage inhibition greater than 70% (at a concentration of 50 µg/mL). In conclusion, these findings suggest that the ethanolic extracts from different parts of D. sulcatum are promising sources of natural active ingredients for further cosmetic and cosmeceutical products.
