“…As shown in Figure 3C, the yield of O. gratissimum essential oil decreased with an increase in temperature under continuous drying. A similar result was obtained in a previous study for the drying of the same species at temperatures of 30, 40, 50, and 60 °C (Santana et al, 2014). In that study, no significant difference was reported in the yield of essential oil extracted from the dry leaves at temperatures of 30, 40 and 50 °C.…”

This study investigated the effect of a drying method with intermittent ratios on the effective drying time, specific energy consumption and essential oil yield of clove basil (Ocimum gratissimum L.) leaves. The drying tests were conducted at the Postharvest Laboratory of Medicinal, Aromatic and Condiment Plants, from the Departamento de Engenharia Agrícola of the Universidade Federal de Viçosa, Viçosa, MG, Brazil (20° 46’ 13.5” S; 42° 52’ 23.3” W, and altitude of 645 m) in October and November 2017. The experiment was conducted by using a 3 × 4 factorial scheme including three drying temperatures at 50, 60 and 70 °C, with four drying processes: continuous drying and the following three intermittent drying/tempering ratios in minutes: 10/20, 15/15 and 20/10. The design was completely randomized and with three repetitions. The application of the 10/20 intermittent ratio reduced the effective drying time and the specific energy consumption. Regarding the essential oil yield, the use of the intermittence presented different results for each temperature of drying; the highest yields were observed with continuous drying at 50 °C and drying with the 20/10 intermittent ratio at 60 °C. The results indicate that intermittent drying at 50 °C is not recommended to preserve essential oil yields.

“…O. gratissimum leaf is rich in essential oil (Ocimum oil) and phenolic compounds. The essential oils are of economic and medicinal importance owning to their antimicrobial activities (Santana et al, ). Among the phenolic compounds identified in O. gratissimum extracts to date are; xanthomicrol, rutin, kaempferol 4 o‐rutinoside, rosmarinic acid, vicenin‐2, caffeic acid, cichoric acid, cirsimaritin and nevadensin, transferulic acid, quercetin (Grayer et al, ; Ola et al, ).…”

Preclinical Research Ocimum gratissimum L. leaves have attracted considerable attention from researchers because of their medicinal value that include anti-inflammatory, analgesic, antimicrobial, and antioxidant activities. In the present study, the toxicity and the protective effect of phenolic extract of O. gratissimum leaf (EAFOg) against acute inflammation and oxidative stress in rats was assessed. EAFOg, enriched in phenols had no cytotoxic effect against CHO-k1 cells, and no lethality against brine shrimp eggs or mice at a dose of 2000 mg/kg. EAFOg (50 and 100 mg/kg) reduced paw edema by 47% and 61%, compared to 29% with the COX-2 inhibitor, SC58125 (1 mg/kg) and 81% with indomethacin (5 mg/kg), respectively. In the rat carrageenan-induced air pouch model, EAFOg reduced exudate volume, leucocyte count, nitrite, TNF-α, and myeloperoxidase activity. EAFOg also protected against carrageenan-induced lipid peroxidation and glutathione depletion. These results provide evidence of the protective effects of EAFOg against acute inflammation and oxidative stress in rats. Drug Dev Res 78 : 135-145, 2017. © 2017 Wiley Periodicals, Inc.

“…This method is successfully employed in various agricultural products (Doymaz, 2009), but for medicinal plants this method is not recommended, because solar drying as commonly leads to photodecomposition reactions (Santana et al, 2014) and the long drying time is undesirable for economic reasons. Chlorophyll is a group of compounds responsible for color intensity of plants.…”

“…The reduction of the water content of freshly harvested medicinal plants is imperative for handling and storage purpose and less susceptible to microorganisms (Tanko et al, 2005: Ghasemi-Pirbalouti et al, 2013. Drying reduces the enzymatic activity inhibiting chemical reaction as hydrolysis, oxidation, and fermentation (Santana et al, 2014). Drying of medicinal plants must be carefully performed in order to preserve the aroma, appearance, and nutritional values (Crivelli et al, 2002).…”
