## 3 Results and Discussion  
### GCMS Analysis  
Plant bioactive compounds have played a substantial role in the drug discovery struggles for the treatment of human ailments [22]. In reality, most antimalarial, anticancer, antibacterial, antioxidant and anti-inflammatory agents are based on natural products, thus suggesting the need to identify novel bioactive compounds from plant origin. Folkloric medicine continues to be an important task in the search for therapeutic drugs for human use [23; 24]. According to the report of [PERSON] et al. [25], the antimalarial activity of _Anmonia senegalensis_ might be due to bioactive compounds such as alkaloids, quassinoids andanthin. In recent years, the importance of phytochemicals has been emphasized due to their noteworthy health benefits [26]. In the present study, GCMS analysis of the chloroform leaf extract of _O. genistifolia_ (Table 1) revealed the existence of the following most significant bioactive compounds, among others: (R)-\(\alpha\)-pinene, camphene, \(\gamma\)-terpinene, eucalypttol, (+)-2-bornanone, bornyl acetate, carryophyllene, aromandendrene, alloaromadendrene, (+)-ledene, (+)-\(\delta\)-cadinene, spatulenol, \(\beta\)-eudesmol, \(\alpha\)-eudesmol, acorenone 1, n-hexadecanoic acid, \(\alpha\)-linolenic acid, ferruginol, D-homopregn-17a(20)-ene, (5.alpha., 17 aE)- and (.+/-.)-demethylsalvicanol. Similarly, the GCMS profile of the ethyl acetate leaf extract of _O. genistifolia_ showed the presence of the following bioactive compounds, among others (Table 1): sabinene (\(\beta\)-thujene), eucalypttol, (+)-2-bornanone, bornyl acetate, caryophyllene, aromandendrene, alloaromadendrene, virdiforene, \(\delta\)-cadinene, (+)-, spatulenol, \(\beta\)-eudesmol, 2-(4a,8-dimethyl-2,3,4,5,6,8a-hexa hydro-1H-naphthalen-2-yl)propan-2- ol, acorenone 1, n-hexadecanoic acid, \(\alpha\)-linolenic acid, ferruginol, benzene, ethenylpentaethyl-6-Iodo-2-methylquinazolin-4(3H)-on and (.+/-.)-demethylsalvicanol. The GCMS profile of the ethanol leaf extract of _O. genistifolia_ showed these bioactive compounds (Table 1): eucalypttol, (+)-2-bornanone, bornyl acetate, caryophyllene, aromandendrene, spatulenol, \(\beta\)-selinenol, \(\gamma\)-eudesmol, acorenone 1, n-hexadecanoic acid, ferruginol, D-homopregn-17a(20)-ene and (5.alpha., 17 aE)-. A comprehensive information about the three crude extracts are presented in the Supplementary data (Tables S1-S3). These bioactive compounds have been acknowledged to be responsible for the different biological activities demonstrated by these crude extracts [27; 28]. From the GCMS profiles of the crude extracts, we observed that the organic solvents used were able to extract similar bioactive compounds, which further buttress analogous biological and pharmacological activities exhibited by the three extracts in our present study. For example, phytol was present in all three extracts and previous studies have highlighted that it has antioxidant, anticancer and antinociceptive effects [29; 30; 31; 32]. In the same vein, hexadecanoic acid is known to exhibit strong antimicrobial and anti-inflammatory activity [33]. Similarly, ferruginol and caryophyllene were also present in all the extracts and their antimalarial activity has been well documented previously [1]. Therefore, fractionation and isolation of pure compounds from the crude extracts are necessary because of numerous bioactive compounds that support the medicinal application of _O. genistifolia_.
