This research explores the phytochemical composition of ripe and unripe White Monkey Kola (WAK) fruits through methanolic extraction and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. A total of 73 compounds were identified in the unripe extract and 69 in the ripe extract, indicating rich chemical diversity across both maturity stages. Quantitative analysis showed that oleic acid was the most abundant compound in both extracts, with concentrations of 13,66% in the unripe and 16,86% in the ripe sample. Other notable compounds in the unripe extract included 1-nonadecene (10.40%), luteol (8.99%), catechin (6.54%), and heptane, 2,6-dimethyl- (8.84%), while the ripe extract was dominated by heptane, 2,6-dimethyl- (12.18%), undecane, 5-methyl- (10.43%), and phenolic antioxidants like lunamarin and 2,4-di-tert-butylphenol (9.67% each). Comparative phytochemical classification revealed 11 major classes, with hydrocarbons and fatty acids & esters being the most prevalent in both samples 20 and 17 compounds respectively in the ripe extract, and 20 and 11 in the unripe. The unripe extract showed higher concentrations of flavonoids and phenolic compounds, indicating stronger antioxidant potential, while the ripe extract contained more fatty acid derivatives and aldehydes, reflecting ripening-associated metabolic shifts. These results suggest that White Monkey Kola possesses significant nutritional and therapeutic value, with potential applications in both functional food and phytomedicine, depending on the stage of maturity.

Auszug aus dem Buch
1.1 Background of the study
The use of plants in traditional medicine remains the cornerstone of primary healthcare in many developing countries around the world, as these plants serve as raw materials for more potent natural compounds. There has, however, been a rapid growth in the field of herbal medicine. White monkey kola nut belongs to the Sterculiaceae family. The nut of White monkey kola is chewed as a masticatory, stimulant, and for its taste during traditional, cultural, and social ceremonies (Olaleye et al., 2019). The Cola parchycarpa plant is known as a wonder plant because every part of it has medicinal significance. White monkey kola is highly valued in African ethnomedicine due to its diverse uses, both social and medicinal, making it an essential ingredient in folk medicine. It has a bitter taste with a slight sweetness. Despite its bitterness, White monkey kola nuts are commonly eaten as a snack and used for their stimulant effects, thanks to their high caffeine content. White monkey kola has also been used as an antidote for poisoning or suspected poisoning, as people chew it to prevent infection or poison when food is suspected to be contaminated by bacteria (Onyeke et al., 2021).

Frequently Asked Questions
What is the primary focus of this research?
The research focuses on analyzing and comparing the phytochemical composition of white monkey kola at two different developmental stages: ripe and unripe.
Which scientific method is used for the analysis?
The study utilizes Gas Chromatography-Mass Spectrometry (GC-MS) to identify and quantify volatile and semi-volatile bioactive compounds within the plant extracts.
Why is white monkey kola considered a "wonder plant"?
It is widely used in African ethnomedicine for its diverse medicinal properties, including antimicrobial, anti-inflammatory, and antidiabetic effects, as well as being a food source.
How does ripening affect the chemical composition of the fruit?
Ripening triggers a transition where antioxidant levels, such as flavonoids, tend to decline, while there is an accumulation of lipid-based molecules, fatty acids, and volatile compounds.
What is the main objective regarding the comparative analysis?
The goal is to determine how the shift in bioactive components during ripening might modulate the fruit's therapeutic efficacy, thereby validating traditional uses.
Which key compounds were identified in the study?
Identified compounds include various fatty acids like oleic acid, esters, alcohols, and alkaloids, which vary in concentration between the ripe and unripe forms.
How does the study support traditional healers?
By providing scientific evidence for the phytochemical differences in maturity stages, it helps validate why traditional healers might prescribe specific stages of the fruit for distinct ailments.
What do the findings suggest for industrial applications?
The results suggest that unripe monkey kola is better suited for antioxidant-rich products, while ripe extracts are more appropriate for lipid-based or energy-enhancing supplements.
