Bottom Line: Its calyces are widely consumed with many uses in Sudanese folk medicine.The results of the antibacterial test indicate that the methanol extract of H. sabdariffa calyces contained effective antibacterial agent(s), revealed a considerable zone of inhibition against all tested Gram-negative and Gram-positive bacteria, and it was a competitor to gentamicin and greatly higher than penicillin which showed weak or no effect.The results of current investigation support the folk medicine application of this plant against different microbial ailments and suggest it as a promising source for new antibacterial agents.

ABSTRACT

Background: Hibiscus sabdariffa L. is a plant native to tropical Africa and intensively cultivated in Sudan. Its calyces are widely consumed with many uses in Sudanese folk medicine.

Materials and methods: The dried calyces of H. sabdariffa were subjected to soak in 80% v/v methanol to get the methanolic extract, which was tested against five Gram-negative and three Gram-positive referenced bacterial strains using disc diffusion method. Selected bioactive phytochemical compounds were also investigated using qualitative methods.

Results: The results of the antibacterial test indicate that the methanol extract of H. sabdariffa calyces contained effective antibacterial agent(s), revealed a considerable zone of inhibition against all tested Gram-negative and Gram-positive bacteria, and it was a competitor to gentamicin and greatly higher than penicillin which showed weak or no effect.

Conclusion: The results of current investigation support the folk medicine application of this plant against different microbial ailments and suggest it as a promising source for new antibacterial agents.

Mentions: Plants, particularly those prescribed against microbial infections since a long time in traditional and folk medicine from different societies could be promising sources for new antimicrobials [3]. In Sudan, the majority of Sudanese people, like many African countries, are still relying on traditional or folk medicine in treatment of diseases which are an integral part of an informal healthcare system, although this popular folk medicine has roots from Islamic and West African medicine [4]. Roselle (Hibiscus sabdariffa L) belongs to Malvaceae family, it is an annual tropical small shrub native to Africa and also distributed in Southeast Asia and Central America [5,6], it is Known locally as Karkadeh. The macerate of the red calyces of this plant [Figure 1] is one of the most famous public Sudanese beverages all over this country and all Sudanese people know and use, which are consumed as hot or cold drinks for the treatment of respiratory tract infections, hypertension, colds, and fever. It is also mixed with other plants to treat malaria [7,8].
