Air kelapa muda dapat memberikan manfaat kesehatan bagi yang mengkonsumsinya. Untuk memperoleh air kelapa muda, masyarakat dapat membelinya pada pedagang-pedagang yang berjualan pada hampir di setiap sudut kota maupun pada rumah makan/restoran. Banyaknya pedagang kelapa muda menyebabkan jumlah limbah sabut kelapa muda semakin meningkat. Pemanfaatan limbah kelapa muda tidak semudah pemanfaatan limbah kelapa tua. Beberapa pemanfaatan limbah kelapa muda yang telah atau sedang diteliti adalah sebagai bahan dasar pembuatan komposit serat alam atau biokomposit serta sebagai pewarna alami pada berbagai produk fesyen. Agar bisa dimanfaatkan secara lebih luas lagi, maka perlu dilakukan uji kandungan metabolit sekunder (uji fitokimia) dari sabut kelapa tersebut, dimana uji fitokimia bertujuan untuk menentukan senyawa aktif yang terkandung dalam suatu sampel dengan menggunakan pelarut yang tepat. Pada penelitian ini dilakukan perendaman sabut kelapa muda menggunakan tiga jenis pelarut yang berbeda kepolarannya, yaitu n-heksan, aseton, dan etanol. Hasil penelitian menunjukkan bahwa etanol merupakan pelarut yang cocok dalam ekstraksi sabut kelapa muda dan berdasarkan hasil uji fitokimia diperoleh senyawa aktif berupa flavonoid, terpenoid dan tannin, serta polifenol.

“…Solanaceae has many uses and is one of the most valuable and varied vegetable families. Several Solanaceae plant species that have economic value have become important model systems in plant research in the field of biology to study plant development, fruit ripening, and food security [2]. Solanum ferox contains terpenoids, steroids, flavonoids, alkaloids, and phenolic compounds.…”

The sour eggplant plant (Solanum ferox L), a vegetable that is frequently used in cooking and is a member of the Solanaceae family, is also used as an antipyretic and to treat syphilis, body aches, lack of appetite, fever, itching, cuts, and bruising. This is due to the presence of several bioactive chemicals that have toxic, rheumatoid, antiviral, anticancer, antibacterial, and anti-asthma properties. The objective of this work was to separate antioxidant and antibacterial substances from Solanum ferox L. leaves. N-hexane and methanol were used to extract the leaves of Solanum ferox. The characterization of chemicals in the n-hexane extract was done while the antioxidant and antibacterial properties of both extracts were examined. UV-Vis spectra, FTIR, proton and carbon nuclear magnetic resonance (1H-NMR and 13C-NMR), and FTIR were used to characterize the compound). Using vitamin C as a reference and the DPPH (1,1-diphenyl-2-picrylhydrazyl) technique to measure free radicals, the antioxidant activity of the Solanum ferox plant extract was assessed. E. coli, S. aureus, and S. subtilis bacteria are used in an agar diffusion method test for antimicrobial activity. The solvent used to dissolve the sample served as the negative control while amoxsan served as the positive standard. One pure substance that has been isolated with success is stigmasterol, with the chemical formula C29H48O. The IC50 of Solanum ferox leaf n-hexane extract at 1218.5 ppm, which included not active, indicated that the IC50 of Solanum ferox leaf methanol extract at 268.5 ppm was ineffective. E. coli is inhibited by n-hexane extract in antibacterial tests at an inhibition value of 9.27 mm. Methanol extracts had an inhibitory potency of 7.82 mm against E. coli and 11.29 mm against S. aureus.
