Labisia pumila var. alata leaves (LP) with a long history of use folk remedy and endemic to the Malay Archipelago, is now supplied worldwide as ingredient of functional foods and beverages. Minerals and heavy metal concentrations in Labisia pumila var. alata folium (LP) of selected geographic origin based on microwave-assisted sample digestion and inductively coupled plasma mass spectrometry (ICP-MS) were determined. Fifteen elements comprising minerals (Ba, Ca, Cr, Co, Cu, Fe, K, Mg, Na, Ni, Rb and Zn) and heavy metals (As, Cd and Pb) were analyzed with an inductively coupled plasma – mass spectrometer (ICP-MS). The highest nutrient concentration was measured in LP from Tilu Mountain (Cu, Na, K, Mg and Zn). The highest values of Ba, Ca, Co, Cr and Fe were detected in LP from Raub. Ni and Rb were highest in LP from Cibeundey Village. As was highest in LP from Raub (0.04 ± 0.00 mg/kg). The highest Pb contents were in LP from Tilu Mountain (2.90 ± 0.10 mg/kg) and LP from Halimunan-Salak Mountain (3.12 ± 0.03 mg/kg), all of which were well within the permissible limits as specified by the U.S. FDA for edible plant parts.
唇形唇形叶(LP)具有悠久的民间偏方使用历史和马来群岛特有，现在作为功能食品和饮料的成分供应世界各地。采用微波消解法和电感耦合等离子体质谱法(ICP-MS)测定了不同产地的唇形叶(Labisia pumila var. alata folium, LP)中矿物质和重金属的含量。用电感耦合等离子体质谱仪(ICP-MS)分析了矿物(Ba、Ca、Cr、Co、Cu、Fe、K、Mg、Na、Ni、Rb、Zn)和重金属(As、Cd、Pb)等15种元素。土壤中Cu、Na、K、Mg和Zn的含量最高。其中Ba、Ca、Co、Cr、Fe含量最高的是罗布鱼的LP。产自Cibeundey村的LP中Ni和Rb含量最高。产自罗布鱼的LP含量最高(0.04±0.00 mg/kg)。铅含量最高的是提鲁山LP(2.90±0.10 mg/kg)和哈利木南-萨拉克山LP(3.12±0.03 mg/kg)，均在美国FDA规定的可食用植物部位允许限量范围内。

Betel leaf (Piper betle L) is a medicinal plant. Its essential oil has antibacterial activity of phenolic compounds and theirs derivatives that can inhibit a wide range of bacteria. Streptococcus pyogenes and Staphylococcus aureus is a bacteria that can cause strep throat (pharyngitis). This study was conducted to determine how to obtain the essential oil of Betel leaf green (Piper betle L.) using steam-water distillation method and determine the antibacterial activity of essential oils of betel leaf (Piper betle L.) against the bacteria Streptococcus pyogenes and Staphylococcus aureus using wells method. Betel leaf 5 kg isolated using steam-water distillation of essential oils produces as much as 9 mL, yield of 0.135%, a specific gravity of 0.750 g / mL, and the refractive index of 1.337. The results of GC-MS analysis of betel leaf green essential oil obtained 10 Most compounds are compounds chavicol, eugenol, germacrene D, caryophyllen, eugenol acetate, 2-allyphenol, β-chamigrene, α-cadinene, terpineol, and α-humulene. Based on the test results of the antibacterial activity of betel leaf that the essential oil of betel leaf green (Piper betle L) at the concentration of 10%, 20%, 30%, and 40% can inhibit the bacteria Streptococcus pyogenes and Staphylococcus aureus, the category of barriers weak to moderate for bacteria Streptococcus pyogenes and weak to strong resistance categories for Staphylococcus aureus bacteria.

Plak gigi terbentuk oleh biofilm yang menutupi permukaan gigi. Biofilm merupakan lapisan lendir yang terdiri dari jutaan sel bakteri, saliva dan sisa makanan. Ketika pembentukan biofilm tidak terkendali, maka akan dengan mudah menebal di permukaan gigi yang disebut dengan plak. Biofilm ini merupakan tempat yang baik untuk kolonisasi dan pertumbuhan berbagai jenis bakteri salah satunya adalah bakteri Streptococcus mutans. Bakteri S. mutans dapat membentuk koloni yang melekat erat pada permukaan gigi dan merupakan bakteri kariogenik yang mampu memfermentasikan sukrosa (karbohidrat) menjadi asam, menurunkan pH permukaan gigi dan menyebabkan mineralisasi gigi. Sehingga untuk pengendalian bakteri tersebut digunakan sediaan yang mengandung antibakteri, salah satunya dari bahan alam yaitu kecombrang. Penelitian ini bertujuan mengetahui aktivitas antibakteri dari ekstrak batang Etlingera elatior yang diekstraksi oleh pelarut berdasarkan perbedaan tingkat kepolaran. Pengujian aktivitas antibakteri ekstrak dibagi menjadi 5 kelompok yaitu untuk ekstrak n-heksana, etil asetat, etanol 20, 40, 60 dan 80%, kontrol positif minosep dan kontrol negatif (DMSO). Hasil skrining fitokimia menunjukkan bahwa tanaman E. elatior mengandung metabolit sekunder flavonoid, tanin, saponin, triterpenoid dan alkaloid. Ekstrak etil asetat memiliki aktivitas antibakteri kategori kuat terhadap S. mutans sebesar 17,22; 17,55; 17,77 dan 18,55 mm, lebih tinggi dibandingkan dari kontrol positif minosep yang memiliki aktivitas antibakteri sebesar 16,55 mm.

Kalkon is a secondary metabolite of the flavonoid group that is found in nature, especially in plants. Kalkon has various activities such as cytotoxic, antiviral, anesthetic, antimicrobial, antiinflammatory, and so forth. The aim of this research is to know the antibacterial activity of kacco-based derived paracetamol compound by using docking method against bacterial protein Escherichia coli and Bacillus subtilis. The results showed that the compound 3(4-Metoxyphenyl) -N(4-Chlorophenyl) Acrylamide, 3(4-Hydroxyphenyl) -N(4-Chlorophenyl) Acrylamide, and 3(4-Hydroxy-3-Methoxyphenyl ) -N(4Chlorophenyl) Acrylamide showed good activity with an average rmsd-refine score <2. The kalkon derivative binds complex with amino acid bacteria such as Ile 173, Asn 267, Lys A449, Thr 265, and Arg A389.
