Gas chromatography–mass spectrometry analysis of the volatile compounds from the ethanol extracts of Bulbine asphodeloides and Helichrysum petiolare.

Abstract

Background: Bulbine asphodeloides and Helichrysum petiolare are important medicinal plants that commonly used in folklore medicine in South Africa for the management of skin ailments such as acne, burns, wounds, eczema, shingles, hives, psoriasis, sores, rosacea, and rashes. Despite their extensive use in traditional medicine, the chemical profiles of these medicinal plants have not been elucidated. Objective: The present study was carried out to identify and compare the gas chromatography– mass spectrometry (GC–MS) profiles of the volatile components from the ethanol extracts of both plants. Materials and Methods: The fresh leaves of both plants were collected from Alice, Eastern Cape, South Africa, and later oven dried and subjected for extraction and these extracts were further subjected to GC–MS analysis using standard procedures. Results: The GC–MS analysis revealed the presence of bioactive terpenes in the volatile components of the ethanol extracts of B. asphodeloides and H. petiolare. Conclusion: The findings reveal the presence of various bioactive compounds which therefore validates the therapeutic importance of these plants in the treatment of skin‑related diseases.
