“…The presence of phenolic compounds in the Pouteria extracts can explain, at least in part, the antioxidant and radical scavenging activities presented by the more polar extracts and fractions (Rice-Evans et al, 1996). In addition, lupeol, ursolic acid and others triterpenes also have demonstrated capacity to intercept free radicals (Bracco et al, 1981;Saleem et al, 2001).…”

RESUMO: "Gênero Pouteria: Química e atividade biológica". O gênero Pouteria pertence à família Sapotaceae e pode ser encontrado em muitos continentes. As plantas desse gênero têm sido utilizadas na construção civil, na alimentação e também na medicina popular. Algumas atividades biológicas são reportadas às espécies desse gênero, tais como, antioxidante, anti-inflamatória, antibacteriana e antifúngica, mas seu real potencial como fonte de novos fármacos ainda é pouco conhecido. Assim, uma revisão sobre a composição química e as atividades biológicas de Pouteria é apresentada, com o intuito de estimular a continuação dos estudos das espécies aqui citadas, e a investigação de outras espécies para as quais não foram encontrados relatos.Unitermos: Pouteria, Sapotaceae, triterpenos, flavonoides, plantas medicinais. ABSTRACT:The genus Pouteria belongs to the family Sapotaceae and can be widely found around the World. These plants have been used as building material, as food, because the eatable fruits, as well as remedies in folk medicine. Some biological activities have been reported to species of this genus such as antioxidant, anti-inflammatory, antibacterial and antifungal. However, the real potential of this genus as source of new drugs or phytomedicines remains unknown. Therefore, a review of the so far known chemical composition and biological activities of this genus is presented to stimulate new studies about the species already reported moreover that species have no reference about chemistry or biological activities could be found until now.

“…The antioxidant properties of aromatic plants and spices Antioxidant capacity and biological activity of essential oil and methanol extract of Hyptis crenata Pohl ex Benth have been indicated as effective in delaying the lipid peroxidation of foods (Bracco et al, 1981;Kramer, 1985;Lagouri et al, 1993;Souza et al, 2007). Tsimidou and Boskou (1994) observed that between the herbs and spices extensively studied, the plants belonging to the Lamiaceae family have significant antioxidant activity.…”

RESUMO: "Capacidade antioxidante e atividade biológica do óleo essencial e extrato metanólico de Hyptis crenata Pohl ex Benth". O óleo essencial das folhas e ramos finos frescos e secos de Hyptis crenata forneceu os seguintes rendimentos, 1,4% e 0,9%. Os constituintes voláteis principais foram a-pineno (22,0%; 19,5%), 1,8-cineol (17,6%; 23,2%), b-pineno (17,0%: 13,8%), cânfora (4,7%; 11,6%), limoneno (5,4%; 4,4%) e g-terpineno (3,5%; 2,4%), totalizando mais de 70% nos óleos. A atividade de seqüestro do radical DPPH para o extrato metanólico (CE 50 , 16,7 ± 0,4 mg/mL) foi comparável ao do BHT (19,8 ± 0,5 mg/mL) mostrando uma significante atividade antioxidante. Os óleos apresentaram baixa atividade. O teor de fenólicos totais (TP, 373,0 ± 15,9 mg GAE/g) e equivalente trolox (TEAC, 226,8 ± 0,5 mg TE/g) confirmaram a atividade antioxidante do extrato metanólico, que pode ser atribuída à presença de compostos fenólicos polares. No teste com larvas de camarão as concentrações letais para o óleo e extrato metanólico foram 6,7 ± 0,2 mg/mL e 13,0 ± 3,7 mg/mL, respectivamente, fornecendo importante evidência de suas atividade biológicas.Unitermos: Hyptis crenata, Lamiaceae, "salva-do-marajó", óleo essencial, atividade antioxidante, teor de fenólicos totais, citotoxidade. ABSTRACT:The essential oils of fresh and dried leaves and fine stems of Hyptis crenata furnished the following yields: 1.4% and 0.9%. The main volatile constituents were a-pinene (22.0%; 19.5%), 1,8-cineole (17.6%; 23.2%), b-pinene (17.0%; 13.8%), camphor (4.7%; 11.6%), limonene (5.4%; 4.4%) and g-terpinene (3.5%; 2.4%), totalizing more than 70% in the oils. The DPPH radical scavenging activity (EC 50 , 16.7 ± 0.4 mg/mL) of the methanol extract was comparable to BHT (19.8 ± 0.5 mg/mL) showing a significant antioxidant activity. The oils showed low activities. The amount of total phenolics (TP, 373.0 ± 15.9 mg GAE/g) and trolox equivalent (TEAC, 226.8 ± 0.5 mg TE/g) confirmed the antioxidant activity of the methanol extract that can be attributed to the presence of polar phenolic compounds. In the brine shrimp bioassay the lethal concentrations (LC 50 ) for the oil and methanol extract were 6.7 ± 0.2 mg/mL and 13.0 ± 3.7 mg/mL, respectively, providing important evidence of their biological activities.

“…Synthetic antioxidants such as butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA) and propyl gallate (PG) have been used as food additives to inhibit the actions of toxic and carcinogenic substances (Chang et al, 1977). Natural antioxidants from natural foods such as herbs (Bracco et al, 1981;Inatani et al, 1982;Pizzocaro et al, 1994), vegetables (Tsushida et al, 1994;Vinson et al, 1998), fruits (Nogata et al, 1996;Wang et al, 1996), oilseeds Fukuda et al, 1985;Medina et al, 1999), spices Chipault et al, 1995;Kramer, 1995;Hettiarachchy et al, 1996), green tea (Amarowicz & Shahidi, 1996) and cereals (Asamari et al, 1996;Maillard et al, 1996;Hendelman et al, 1999) have been studied, and some of them, such as ascorbate and tocopherols, are currently used in a variety of food products. a-Tocopherol, a form of vitamin E, is widely used as a natural antioxidant.…”

Antioxidative activities of thirty kinds of citrus essential oils and their fourteen components against linoleic acid oxidation were examined by a thiocyanate method. The tocopherol contents of these oils were determined by high-performance liquid chromatography monitored at 290 nm. All the citrus essential oils and the flavor components showed inhibitory effects against linoleic acid oxidation. Highest antioxidative ability was observed in the essential oils of yuzu, lemon, hassaku, sudachi, mochiyu, yuko and Tarocco orange. Antioxidative activities of ␤-pinene, myrcene, ␣-terpinene, ␥-terpinene and decanal were higher or similar to that of d d d d-tocopherol. Tocopherols were contained abundantly in the essential oils of limes, Valencia orange, yuzu and lemons. However, there was little correlation between tocopherol contents and antioxidative activities in citrus essential oils. The composition of terpene compounds seems to be a major factor in the antioxidative activities of these oils.
