Abstract

Telah dilakukan enkapsulasi hiptolida dengan penyalut kitosan, pektin, dan tripolifosfat (TPP) menggunakan metode koaservasi kompleks. Proses enkapsulasi dibuat dalam bentuk empat formula: formula 1 kitosan (BM = 500 KDa) 1% dan pektin 0,05%; formula 2 kitosan (BM = 168 KDa) 1% dan pektin 0,05%; formula 3 kitosan (BM = 168 KDa) 1% dan pektin 0,05% yang disertai perlakuan sonikasi; formula 4 kitosan 0,04%, pektin 0,08%, dan TPP 0,01%. Karakterisasi ukuran partikel formula enkapsulasi menggunakan particle size analyzer (PSA), efisiensi enkapsulasi (EE) menggunakan spektrofotometer UV-Vis, dan interaksi gugus fungsi hiptolida dalam masing-masing formula menggunakan spektrometer Raman. Hasil karakterisasi ukuran partikel formula 1 diperoleh 111,885 µm, formula 2 sebesar 118,389 µm, formula 3 sebesar 118,388 µm, dan formula 4 yaitu 20,578 nm, dengan efisiensi enkapsulasi 97,801%. Berdasarkan penelitian yang telah dilakukan, disimpulkan bahwa formula 4 dengan komposisi kitosan 0,04%, pektin 0,08%, dan TPP 0,01% merupakan formula optimum enkapsulasi hiptolida yang mampu membentuk nanopartikel berukuran 20,578 nm.

Abstract

Hyptis pectinata (L.) poit, popularly known in the world as “comb bushmint” is a medicinal plant commonly used for the treatment of throat and skin inflammations, bacterial infection, pain and cancer. The objective of this research is to determine the cytotoxic and antiproliferative effect under Hyptis pectinata ethanolic extract (HPE) treatment on breast cancer cells. The effect HPE of on cytotoxicity was examined by MTT assay on MCF-7 breast cancer cells. This assay also used to determine cell proliferation over 3 days of treatment with 1.5 – 100 µg/mL HPE. HPE showed that exhibited cytotoxic effects with IC50 value of 30 µg/mL for 24 hours and changes the physiological morphology on MCF-7 cells. Interestingly, the treatment of HPE for 48 and 72 hours highly decreases cell viability on MCF-7 with dose and time-dependent manner compared to untreated cells. These results indicate that HPE has antiproliferative activities and maybe the potential to be developed as a natural chemotherapeutic agent.Keywords: Hyptis pectinata (L.) poit extract, cytotoxicity, antiproliferative, MCF-7 cells
Analysis of Total Phenolics, Flavonoids, and Antioxidant Activity of Cashew Leaf Extract (Anacardium occidentale L.) with Varying Ethanol Concentrations: Analisis Total Fenolik, Flavonoid, dan Aktivitas Antioksidan Ekstrak Daun Jambu Mete (Anacardium occidentale L.) dengan Variasi Konsentrasi Etanol Kurniasari, Risma; Suzery, Meiny; Cahyono, Bambang

Abstract

This study evaluated the effectiveness of various ethanol concentrations (50%, 70%, and 96%) in extracting bioactive compounds from cashew leaves (Anacardium occidentale). Parameters analyzed included total phenolics, total flavonoids, and antioxidant activity using the DPPH and H2O2 methods. The results showed that the 70% ethanol extract produced the highest total phenolic and flavonoid content as well as significant antioxidant activity compared to other ethanol concentrations. This study offers practical insights for pharmaceutical, cosmetic, and nutraceutical industries in selecting the optimal solvents for cashew leaf extraction. Additionally, the analysis showed that the 70% ethanol extract offered an optimal balance between extraction efficiency and antioxidant activity, making it the most efficient solvent for commercial use.

Abstract

The effects of temperature and heating time on the degradation and antioxidant activity of anthocyanin compounds from roselle petals (Hibiscus sabdariffa L.) have been evaluated from this research. The purpose of this study is to determine, the degradation and antioxidant activity of anthocyanin compounds on variations of temperature and heating time. In this study anthocyanin was extracted from roselle petals using ethanol solvent at 25oC. Then the anthocyanin extract obtained was dissolved into aqueous solution. The solution was then heated at 40oC, 60oC and 80oC for 60 minutes. The degradation of anthocyanin compounds was analyzed by calculating the total of anthocyanin contents, while the antioxidant activity was evaluated using the DPPH method. The results showed that Total Anthocyanin Content (TAC) from the extract solution before heating was 144.28 mg/L. Meanwhile the total value of anthocyanin in the 60 minutes after heating at 400C, 600C and 800C are 108.88 mg/L, 88.84 mg/L and 63.78 mg/L respectively. Heating at 80oC decreases antioxidant activity by increasing the IC50 value to 86.8 ppm higher than the conditions before heating. The increase of temperature and length of the heating process made the anthocyanin structure degraded. Degradation was indicated by the reduction of total anthocyanin content and the decrease of antioxidant activity.
