“…It has been reported that conventional refining does not significantly affect sterol composition. Phytosterol contents in vegetables are known to vary due to different factors such as variety, season, extraction and other technological procedures (Li et al, 2007;Cercaci et al, 2007).…”

SUMMARY:In this study, the total lipid content and sterol compositions were determined during the development of milk thistle seeds. The oil content increased to a maximum value of 36±1.7% and then declined to reach a value of 30.5±0.9% at full maturity. The sterol content of milk thistle seeds was affected by the ripening degree of the seeds. At the early stages of seed maturation, Δ 7 -stigmastenol was the most abundant sterol followed by β-sitosterol. However, at full maturity, β-sitosterol was the most predominant sterol (46.50±0.8%). As the seed developed, campesterol and stigmasterol amounts increased, while Δ 7 -avenasterol content decreased. It can be concluded that milk thistle seed oil has a characteristic sterol pattern comparable to the ones elucidated for olive oil and corn oil. The extracted oil from milk thistle seeds is rich in phytosterols and could be used in food preparation and human nutrition.

En este estudio se determinaron la composición de lípidos totales y esteroles durante el desarrollo de semillas de cardo mariano. El contenido de aceite incrementó a un valor máximo de 36±1,7% y posteriormente disminuyó hasta alcanzar un valor de 30,5±0,9% cuando la maduración fue completa. El contenido de esteroles de las semillas de cardo mariano se ve afectado por el grado de maduración de las semillas. En las primeras etapas de la maduración de las semillas el Δ7-estigmastenol fué el esterol más abundante, seguido de β-sitosterol. Sin embargo en plena madurez, β-sitosterol fue el esterol predominante (46,50±0,8%). A medida que las semillas se desarrollan las cantidades de campesterol y estigmasterol aumentan, mientras que el contenido Δ7-avenasterol disminuye. Se puede concluir que el aceite de semillas de cardo mariano tiene un patrón característico de esteroles en comparación con lo especificado para los aceites de oliva y de maíz. El aceite extraído de las semillas del cardo mariano es rica en fitoesteroles y podría ser utilizado en la preparación de alimentos y en nutrición humana.

“…Under natural in vivo conditions, propagation becomes difficult as a result of various germination obstacles in Hippophae sp. seeds (Li and Schroeder 2003;Busing and Slabaugh 2008;Airi et al 2009;Frochot et al 2009). These obstacles are mainly because of hard seed coat or embryo dormancy that could be overcome by various chemical and mechanical treatments (Landis et al 1996).…”

Germination and short-term storage of Hippophae rhamnoides L. seeds and its ex-situ reintroduction potential assessment under North East Indian conditions

Germination efficiency of freshly harvested Hippophae rhamnoides seeds collected from cold desert of Ladakh outside its native place under in vivo glass house condition recorded a highest of 73% germination in soilrite at 22±2°C and 60-70% RH within three weeks at Guwahati, North East India. Germination of seeds was significantly enhanced to a maximum of 90% under in vitro condition in 1/4 th Murashige & Skoog (MS) medium supplemented with 3% sucrose and 2% activated charcoal within two weeks. Glass house acclimatized healthy seedlings after been introduced to natural climatic conditions of Shillong and Guwahati of North East India showed inadequate survivability. Unlike storage at room temperature which is detrimental for seed viability, low temperature storage under refrigeration and natural climatic condition of Ladakh retains viability for prolonged period.

“…Isofructosterol is present in concentrations of 10-20% in SB seed oil and of 2-5% in the SB fruit pericarp oil. Campesterol, stigmasterol, citrostadienol, avenasterol, cycloartenol, and obtusifoliol have also been identified in the seed oil [29,39].…”

Sea buckthorn (Hippophae rhamnoides L., Elaeagnaceae.) is a thorny shrub that has small, yellow to dark orange, soft, juicy berries. Due to hydrophilic and lipophilic ingredients, berries have been used as food and medicine. Sea buckthorn (SB) oil derived from berries is a source of valuable ingredients for cosmeceuticals. The unique combination of SB oil ingredients, in qualitative and quantitative aspects, provides multiple benefits of SB oil for internal and external use. Externally, SB oil can be applied in both healthy and damaged skin (burns or skin damage of different etiology), as it has good wound healing properties. Due to the well-balanced content of fatty acids, carotenoids, and vitamins, SB oil may be incorporated in cosmeceuticals for dry, flaky, burned, irritated, or rapidly ageing skin. There have been more than 100 ingredients identified in SB oil, some of which are rare in the plant kingdom (e.g., the ratio of palmitoleic to γ-linolenic acid). This review discusses facts related to the origin and properties of SB oil that make it suitable for cosmeceutical formulation.
