Abstract

Strawberries (Fragaria sp.) have many varieties spread across Indonesia. Pancasari Village, Buleleng is a strawberry producing area in Bali, there are several strawberry varieties cultivated by strawberry farmers in Bali, including the Rosalinda variety which has a sweet taste and the Osogrande has a sour taste. The purpose of this research is to determine the compounds contained in the fruits of these two varieties and to determine their antioxidant activity. Phytochemical analysis was performed using the GC-MS (Gas Chromatography-Mass Spectrometry) method, antioxidant activity was performed using the DPPH method. The results showed that the thick ethanol extract of (Fragaria x Ananassa) the Rosalinda and Osogrande varieties contained the same compound, namely 5-Hydroxymethylfurfural which has a function as an antioxidant, with 7 compounds that have known uses in the Rosalinda variety and 11 compounds in the Osogrande variety. The antioxidant activity of thick ethanol extract of the Rosalinda strawberry fruit is higher with IC50 of 10,05 ppm than the thick ethanol extract of Osogrande variety strawberry fruit with IC50 of 10,47 ppm, which means both are classified as having very strong antioxidant activity.

Abstract

Basil (Ocimum spp.) is an aromatic plant and is the wealthiest essential oil-producing genera from the Lamiaceae family. Due to the various phytochemical compounds or secondary metabolites, Basil has the potential of medicinal plant germplasm as a source of biopharmaceuticals. Several types of Basil grow in Bali, especially in Tabanan Regency, but their morphological characteristics have yet to be identified. This study aims to identify the morphological characteristics of the four types of Basil found growing at that location: Kecarum, Selasih, Tulasi, and Ruku-ruku. This research was conducted by characterizing the characteristics of the parts of the basil plant, including the morphology of the crown (Botany), stem (Caulis), flowers (Flos), leaves (Folium), and fruit (Fructus). The results of the characterization showed that there were similarities between the four types of Basil and differences in crown shape, plant height, the direction of branch growth, type of branching, leaf shape, color (leaves, stems, flowers, fruit), leaf tips, and leaf layout. , and the base of the leaf. Based on the morphological identification, Kecarum and Selasih have similar morphology to Ocimum americanum L and Ocimum basillicum. Tulasi and Ruku-ruku are morphologically identical to Ocimum sanctum var. Rama (red holy basils) and Ocimum campechianum. Keywords: Biopharmaceuticals, Basil, Lamiaceae, Morphology, Ocimum spp.
