Abstract

Staphyloccocus aureus merupakan salah satu bakteri penyebab penyakit menular di Indonesia. Penelitian ini bertujuan untuk mengidentifikasi komponen senyawa yang terdapat pada ekstrak n-butanol daun tenggulun (Protium javanicum Burm. F.) dan mengidentifikasi konsentrasi hambat minimum yang menghambat pertumbuhan bakteri S.aureus. Metode ekstraksi yang digunakan adalah maserasi. Uji aktivitas antibakteri menggunakan metode sumur difusi dan dentifikasi senyawanya menggunakan LC-MS/MS (Liquid Mass Spectrometry-Tandem Mass Spectrometry). Serbuk daun tenggulun sebanyak 1 kg dimaserasi dengan metanol, menghasilkan 90,58 g ekstrak kental metanol yang dipartisi dengan n-butanol. Ekstrak n-butanol pekat pada konsentrasi 20% mampu menghambat pertumbuhan S.aureus secara kuat dengan dengan diameter zona hambat sebesar 16,66 mm dan memiliki konsentrasi hambat minimum (KHM) sebesar 8,75 mm pada konsentrasi 1%. Pemisahan komponen senyawa pada ekstrak n-butanol dilakukan dengan metode kromatografi kolom dengan silika gel sebagai fase diam dan fase gerak etil asetat : asam asetat : asam formiat : air dengan perbandingan 10 : 1 : 1 : 2,6 , dimana hasil pemisahannya diperoleh 5 fraksi gabungan (FA, FB, FC, FD, FE). Dalam penelitian ini hanya Fraksi A dan E yang relatif murni secara kromatografi lapis tipis. Hasil identifikasi fraksi A dengan LC-MS/MS, diduga mengandung senyawa Kokamidropropil betain, 2-feniletanol dan Morin. Sementara itu pada fraksi E diduga mengandung senyawa Rutin. Kata Kunci: antibakteri, daun tenggulun (Protium javanicum Burm. F), LC MS/MS, Staphylococcus aureus. ABSTRACT One of the microorganisms that causes infectious disorders in Indonesia is Staphyloccocus aureus (S.aureus). According to preliminary research Tenggulun leaves can prevent the growth of S.aureus. In order to stop the growth of S.aureus, this study was set out to estimate the minimum inhibitory concentration of an n-butanol extract from tenggulun leaves (Protium javanicum Burm. F.) and to characterize its components. Maceration was utilized to extract the tenggulun leaves, agar well diffusion method was used to test for antibacterial activity, and Liquid Mass Spectrometry-Tandem Mass Spectrometry (LC-MS/MS) was applied to identify the chemicals. One kilogram of tenggulun leaf powder was macerated in metanol to produce 90.58 grams of thick methanol extract divided among with n-hexane, ethyl acetate, and n-butanol to be partitioned. The growth of S.aureus bacteria could be inhibited by the concentrated n-butanol extract at a concentration of 20% with an inhibition diameter of 16.66 mm and the minimum inhibitory concentration of 1% was 8.5 mm. By using column chromatography based on silica gel as the stationary phase and ethyl acetate : acetic acid : formic acid : water in the ratio of 10 : 1 : 1 : 2.6 as the mobile phases, the component of chemicals in the n-butanol extract were separated into 5 mixed fractions (FA, FB , FC, FD, FE). Only relatively pure fractions A used in this study to be identified using a thin layer chromatography. According to the results of the LC-MS/MS, identification of fraction A, it was assumed that this fraction comprised the substances of Cocamidropropyl betaine, 2-phenylethanol, and 2-(2,4-Morin. Meanwhile, the fraction E contained the substance of Rutin. Keywords: antibacterial, LC MS/MS, tenggulun (Protium javanicum Burm. F), Staphylococcus aureus.

Abstract

Colocasia esculenta L yang dikenal sebagai Talas merupakan tanaman herba menahun yang secara tradisional seluruh bagian tanaman dimanfaatkan sebagai bahan obat. Pada peneltian ini, toksisitas ekstrak etanol daun talas dan hasil partisinya diuji dan kandungan senyawa aktif pada ekstrak yang paling toksik diidentifikasi. Pengujian toksisitas dilakukan dengan metode Brine Shrimp Lethality Test (BSLT) dan identifikasi senyawa aktif dengan Liquid Chromatography Mass Spectrometry Tandem Mass Spectrometry (LC-MS/MS). Sampel daun talas sebanyak 1 kg dimaserasi dengan etanol 96% menghasilkan 60,01 g ekstrak kental etanol yang bersifat toksik dengan nilai LC50 sebesar 89,52 ppm. Toksisitas hasil partisi ekstrak etanol dengan pelarut n- heksana, etil asetat, n-butanol, dan air memberikan nilai LC50 berturut-turut 68,13; 191,69; 425,80; dan 678,36 ppm sehingga ekstrak n-heksana dapat dikatakan bersifat paling toksik dibandingkan ekstrak lainnya. Pemisahan senyawa aktif pada ekstrak n-heksana dilakukan dengan metode kromatografi kolom dengan silica gel sebagai fase diam dan dielusi secara gradien dengan fase gerak n-heksana dan kloroform menghasilkan 12 fraksi gabungan dengan toksisitas yang relatif tinggi terdapat pada fraksi C dan D dengan nilai LC50 berturut-turut 23,88 dan 106,18 ppm. Fraksi aktif C diduga mengandung senyawa N,N-dimetil-2- [6- metil-2-(4-metilphenil) imidazol [1,2-a] piridin-3-il] asetamide (zolpidem) dan pada fraksi D diduga mengandung senyawa asam (9Z,12Z,15Z)- oktadeka-9,12,15-trienoat (asam linolenat). Kata Kunci: Artemia salina Leach, Brine Shrimp Lethality Test (BSLT), Colocasia esculenta L, daun talas, toksisitas ABSTRACT Colocasia esculenta L, known as taro, is a perennial herb traditionally used in its entirety for medicinal purposes. This study tested the toxicity of taro leaf ethanol extract and its fractions, and identified the active compounds in the most toxic extract. Brine Shrimp Lethality Test (BSLT) was used to test for toxicity, and LC-MS/MS was used to identify active compounds. A sample of 1 kg of taro leaves was macerated with 96% ethanol, yielding 60.01 g of toxic ethanol extract with an LC50 value of 89.52 ppm. Toxicity partitioning of the ethanol extracts using n-hexane, ethyl acetate, n-butanol and water as solvents gave LC50 values of 68.13, 191.69, 425.80 and 678.36 ppm, respectively, indicating that the n-hexane extract was the most toxic. Separation of the active compounds in the n-hexane extract was performed using column chromatography with silica gel as the stationary phase and gradient elution with n-hexane and chloroform as the mobile phases, resulting in 12 combined fractions. The fractions with relatively high toxicity were fractions C and D with LC50 values of 23.88 and 106.18 ppm respectively. The active fraction C may contain the compound N,N-dimethyl-2-[6-methyl-2-(4-methylphenyl)imidazole [1,2-a]pyridin-3-yl]acetamide (zolpidem) and the fraction D probably contains compounds (9Z,12Z,15Z)-octadeca-9,12,15- trienoic acid (linolenic acid).

Abstract

Asap rokok merupakan salah satu penyedia radikal bebas eksogen yang dapat menimbulkan stres oksidatif dan berpotensi menyebabkan penyakit degenerative. Tenggulun (Protium javanicum Burm. f.) merupakan salah satu tanaman yang berpotensi sebagai antioksidan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak metanol daun tenggulun terhadap kadar malondialdehid (MDA) dan aktivitas superoksida dismutase (SOD) pada darah tikus Wistar yang dipapar asap rokok. Penelitian ini merupakan penelitian eksperimental dengan rancangan acak kelompok dengan posttest-only control group design. 24 ekor tikus putih jantan galur Wistar dibagi dalam 4 kelompok yaitu kelompok kontrol P0 (hanya diberi paparan asap rokok); kelompok perlakuan P1, P2, dan P3 (diberi ekstrak metanol daun tenggulun dengan dosis berturut-turut 50, 100, dan 200 mg/kgBB dan paparan asap rokok). Semua kelompok dipapar asap rokok dengan dosis 3 batang per hari selama 15 menit selama 14 hari. Pada hari ke-15, darah masing-masing tikus diambil untuk dianalisis kadar MDA dan aktivitas SOD. Hasil penelitian menunjukkan bahwa kelompok kontrol P0 memiliki kadar MDA tertinggi yaitu 6,73 ± 0,47 µM dan aktivitas SOD terendah yaitu 1,01 ± 0,12 ng/mL dibandingkan dengan kelompok perlakuan P1, P2, dan P3. Hal ini menunjukkan bahwa paparan asap rokok menyebabkan stress oksidatif. Pemberian ekstrak dengan dosis 50, 100, dan 200 mg/Kg BB secara signifikan (p<0,05) menurunkan kadar MDA dan meningkatkan aktivitas SOD jika dibandingkan dengan kontrol. Semakin tinggi dosis ekstrak yang diberikan, maka kadar MDA cenderung semakin menurun dan aktivitas SOD meningkat. Pemberian ekstrak metanol daun tenggulun dengan dosis 200mg/Kg BB (P3) memberikan hasil terbaik dengan kadar MDA terendah yaitu sebesar 2,91 ± 0,22 µM dan aktivitas SOD tertinggi sebesar 2,73 ± 0,23 ng/mL pada tikus Wistar yang terpapar asap rokok. Pada penelitian ini dapat disimpulkan bahwa ekstrak metanol daun tenggulun secara signifikan mampu menurunkan kadar MDA dan meningkatkan aktivitas SOD pada tikus yang terpapar asap rokok. Kata kunci: asap rokok, malondialdehida, Protium javanicum Burm.f, superoksida dismutase. ABSTRACT Cigarette smoke is a source of free radicals that trigger oxidative stress which can cause inflammation and lung damage. Tenggulun (Protium javanicum Burm. f.) is a plant that is known to have potential as an antioxidant. This study aims to determine the effect of giving tenggulun leaf methanol extract on malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity in the blood of Wistar rats exposed to cigarette smoke. This research is a randomized posttest-only control group design using 24 male white Wistar rats which were divided into 4 groups namely the control group (P0), only given exposure to cigarette smoke; the treatment group (P1; P2, and P3) were exposed to cigarette smoke and given 50, 100, and 200 mg/Kg BW of methanol extract of tenggulun leaves respectively. All groups were exposed to cigarette smoke at a dose of 3 cigarettes per day for 15 minutes for 14 days. On the 15th day, the blood of each rat was taken to analyze its MDA level and SOD activity. The results showed that the control group (P0) had the highest MDA level of 6.73 ± 0.47 µM and the lowest SOD activity of 1.01 ± 0.12 ng/mL compared to the treatment groups P1, P2, and P3. Administration of the extract at doses of 50, 100, and 200 mg/Kg BW significantly (p<0.05) reduced MDA levels and boosted SOD activity when compared to control. The higher the extract dose given, the levels of MDA reduced and SOD activity tends to increase. In this study, the administration of methanol leaves extract of tenggulun with a dose of 200mg/Kg BW (P3) on Wistar rats exposed to cigarette smoke gave the best results with MDA level of 2.91 ± 0.22 µM and SOD activity of 2.73 ± 0.23 ng/mL. The study concluded that the methanol extract of tenggulun leaves significantly reduced MDA levels and boosted SOD activity in rats exposed to cigarette smoke. Keywords: cigarette smoke, malondialdehyde Protium javanicum Burm.f, superoxide dismutase.

Abstract

This community service activity aims to improve the quality and competitiveness of traditional snacks in Sangging Kusamba Village, Klungkung, by utilizing red dragon fruit (Hylocereus polyrhizus) pulp extract as a natural dye. Extraction was carried out using a maceration method using 90% ethanol. The characterization results using LC-MS Shimadzu LCMS-8040 showed the presence of betanidin pigments (2.28%), dopaxanthin-quinone (2.27%), valinebetaxanthin (2.12%), 3-O-methylquercetin (2.38%), kaempferol 3-O-galactoside (3.18%), kaempferol 7-O-D-glucopyranoside (2.40%), quercetin 3-rutinoside (2.18%), isorhamnetin 3-O-neohesperidoside (2.92%), betanin (0.94%), isobetanin (0.94%), and neobetanin (1.61%) were detected and contributed to the antioxidant activity of the extract. The presence of betacyanin and betaxanthin pigments plays a role in providing bright red-purple to orange colors, while flavonoid compounds (quercetin, kaempferol, isorhamnetin) and phenolics (ferulic acid, vanillic acid) support the antioxidant activity of the extract. Implementation in traditional snack business groups shows that natural dyes from red dragon fruit produce bright, stable colors, and are more in demand by consumers than synthetic dyes. Thus, the use of red dragon fruit extract can be a functional food solution that is safe, environmentally friendly, and has high economic value. These results indicate that dragon fruit flesh can be used effectively in this community service aims to develop natural dyes based on red dragon fruit peel as a safer alternative to synthetic dyes.
