Distribution
Geographic Regions
Citrus exhibits a widespread distribution that spans across much of the African continent and several oceanic regions. In the Atlantic, these plants are found throughout Macaronesia, including the Canary Islands and Madeira, as well as in Cape Verde. The genus also maintains a strong presence in Northeast Tropical Africa, stretching through specific territories such as Ethiopia. Within these diverse landscapes, certain populations are even noted to extend into areas like Chad. This extensive range highlights the remarkable adaptability of the citrus genus across varied African and island environments.

Identification
Biological Activities
Citrus plants are increasingly recognized for their significant therapeutic potential in modern medicine. Research indicates that plant-derived vesicles from citrus can exhibit inherent anticancer effects by inhibiting cell proliferation and inducing apoptosis. Beyond oncology, members of the Citrus genus are well-documented for their potent antimicrobial activities. Specifically, extracts from Citrus sinensis have demonstrated promising antileishmanial properties against parasites like Leishmania amazonensis. These combined biological activities position citrus as a vital resource for developing new pharmacological treatments.
Compounds
Citrus fruits are rich sources of various phytochemicals, most notably a diverse group of beneficial flavonoids. These plants contain specific compounds such as naringin and its aglycone form, naringenin, which demonstrate significant antioxidant and anti-inflammatory properties. Additionally, citrus species are known to contain hesperidin, a flavonoid that has shown potential in suppressing clinical symptoms of arthritis. The genus also contains limonoids, including limonin, which has been studied for its ability to inhibit tumor cell proliferation and target viral proteins. Together, these diverse chemical constituents highlight the significant medicinal and health-promoting value found within the citrus family.
Conditions
Citrus cultivation alters soil properties by impacting soil organic carbon (SOC) and alkaline phosphatase (ALP) activity. These changes in soil chemistry and enzyme levels ultimately drive phosphorus (P) availability within karst and non-karst environments. In medical contexts, citrus fruits are frequently utilized as herbal remedies to treat COVID-19, although studies show they do not significantly impact hospitalization rates. Furthermore, plant-derived vesicles from citrus exhibit inherent anticancer effects by inhibiting cell proliferation and inducing apoptosis. Collectively, these findings demonstrate the diverse ways citrus interacts with both soil ecosystems and human health.
Preparations
Citrus is prepared as auraptene (AUR) to study its potential for suppressing tumor growth in human squamous cell carcinomas. The plant is also prepared as citrus in various dietary forms to serve as a nutraceutical for managing cognitive decline. Research demonstrates that citrus is prepared as essential oil and essential oils extracted from leaves or peels to utilize their antioxidant and antiproliferative properties. Additionally, citrus is prepared as extracts to serve as natural, plant-derived fungicides for the preservation of fruit. These various preparations highlight the diverse medicinal, nutritional, and protective applications of the genus.
Parts used
Citrus plants are highly versatile biological resources that offer a wide array of medicinal and commercial benefits through their various anatomical structures. The seeds of these plants are particularly notable for containing limonoids, which serve as promising candidates for cancer chemoprevention and other therapeutic activities. Beyond the seeds, the flowers of species like the Satsuma mandarin are utilized in traditional medicines and teas due to their unique chemical constituents and antioxidant properties. Furthermore, the fruit remains a commercially vital crop, providing essential oils that are indispensable to the perfume, food, and beverage industries. Together, these diverse parts—the seed, the flower, and the fruit—demonstrate the immense pharmacological and economic value of the Citrus genus.
