PENENTUAN KADAR FENOLIK TOTAL EKSTRAK ETANOL DAUN NILAM (Pogostemon cablin Benth.) DENGAN METODE SPEKTROFOTOMETRI UV-VIS

Abstract

One of the plants that is well known in the community and is used as a traditional medicine is patchouli (Pogostemon cablin Benth.). It contains essential oils, flavonoids, saponins, tannins, glycosides, terpenoids and steroids. The alcohol content, such as patchouli alcohol and its derivatives, phenol, and a group of terpenoids in patchouli oil has antibacterial activity. The aim at this research to determine the total phenolic condition the ethanol extract from the patchouli leaves. The extract obtained was analyzed ist content using UV-Vis spectrophotometer. The measurements were done at the maximum wavelength of 662,85 nm. The result showed that the total phenolic in patchouli leave is 327,84 mgGAE /gram of extract.

Phytochemical Screening and Total Phenolic Compounds of Red Ginger (Zingiber officinale) and Secang Wood (Caesalpinia sappan) As Preliminary Test of Antiarthritis

“…Phenol is a secondary metabolic compound that is widely found in plants. Phenolic compounds in nature have a variety of structures such as flavonoids, phenols, polyphenols (lignins, melanins, tannins) (Tahir et al 2017). Phenolic compounds in plants have several pharmacological effects such as antioxidant, anti-inflammatory, anti-proliferative, antimutagenic, antimicrobial, anti-carcinogenic, and prevention of heart disease.…”

Disaster education through the adaptation of the werewolf game and acehnese local wisdom

“…Third, consuming jamblang (syzygium cumini) and processed patchouli (health supplements) Based on various studies, it is said that patchouli and jamblang have multiple health benefits. For example, patchouli is often used as a traditional medicine that functions as an antidepressant, decongestant, headache medicine, antiinflammatory, anti-inflammatory, antiasmatic, antimicrobial and others [5,16]. Jamblang also contains antioxidants close to vitamin C with IC50 score of 8.85, which is categorized as very active antioxidants, which increase the body's immunity and functions as anti-viral, anti-bacterial, anti-asthmatic, anti-allergic, infectious drugs, and others [3,17].…”

“…Aceh has local wisdom which based on research by experts, has various benefits in anticipating potential disasters such as Rumoh Aceh, patchouli, jamblang, and Nandong Smong from Simeulue, which have been known for generations [3][4][5]. Local wisdom is very suitable to be adopted and used to preserve and introduce Acehnese culture to the community, Corresponding author: okta@unsyiah.ac.id especially millennials who have been distracted by globalization [6].…”

Pengaruh Lama Pemanasan Proses Fermentasi Terhadap Kadar Fenolik Total Dan Aktivitas Antioksidan Bawang Hitam

“…Asam galat dan sampel yang direaksikan dengan reagen Folin-Ciocalteu menghasilkan larutan berwana kuning kehijauan dan membentuk kompleks berwarna biru setelah dilakukan penambahan larutan Na2CO3 seperti pada Gambar 2. Penambahan Na2CO3 berfungsi untuk memberikan suasana basa pada larutan [30,31]. Reaksi tersebut membentuk kompleks molybdenum-tungsten berwarna biru yang terbentuk karena senyawa fenolik mengalami disosiasi membentuk ion fenolat yang mereduksi fosfomolibdat-fosfotungat [28,32] dimana penyerapan maksimum bergantung pada konsentrasi larutan alkali dan senyawa fenolik [33].…”
