Gas chromatography-mass spectrometry analysis, hepatoprotective and antioxidant activities of the essential oils of four Libyan herbs
Following an ethnobotanical survey for hepatoprotective remedies, four Libyan medicinal plants from family Lamiaceae; Ajuga iva (L.) Schreber, Marrubium vulgare L., Rosmarinus officinalis L. and Thymus capitatus Hoff. et Link growing widely in Beida, Libya, were selected for our study. The chemical composition of essential oils hydrodistilled from the dried aerial...

High performance liquid chromatography (HPLC) analysis of embelin in different samples of Embelis ribes Burm. f. - a threatened medicinal plant of India
Embelia ribes.Burm.f. is one of the important medicinal plants of India. Six samples ofEmbelia were collected from different geographical regions of India. The seed extract was isolated and analyzed for the principle bioactive constituent, embelin, by high performance liquid chromatographic (HPLC) method. All the samples showed characteristic peaks of embelin at the same retention time as that of standard...

Conservation of endangered medicinal tree bael (Aegle marmelos) through seed priming
In cultivation of medicinal trees, seed germination is a very important problem. Various seed enhancements are being adopted nowadays to improve seedling emergence. Among these seed enhancement, seed priming is an efficient method for increasing of seed vigour and improvement of germination and seedling growth. The laboratory experiment was conducted at the Department of Seed Science and Technology, Tamil Nadu...

Separation and purification of chlorogenic acid from Lonicera japonica Thunb. leaves exact with macroporous resins
Chlorogenic aicd is a main bioactive constituent in Lonicera japonica Thunb. leaves. In this study, a simple method for separation and purification of chlorogenic acid from L. japonicaleaves was established with macroporous resins. The performance and adsorption characteristics of four macroporous resins had been evaluated and D-101 was affirmed to be the suitable resin for the separation of chlorogenic...

Strategies to improve poor seed germination in Stevia rebaudiana, a low calorie sweetener
Expanding cultivation of exotic ‘stevia’ in mid- and low-hill areas of Himachal Pradesh, India, is difficult because of the problem of low seed fertility. The objectives of the present study were to devise strategies to produce fertile seed. Two distinct compatible morphotypes were isolated, which when used in pollination produced fertile seeds, whereas self-pollination always resulted in sterile seed set,...

Productive performance, litter characteristics and carcass defects of the broiler chickens given drinking water supplemented with Satureja khuzistanica essential oils
Two trials were conducted to examine the effect of Satureja khuzistanica essential oils (SkEO) on productive performance using 420 Cobb 500 broiler chicks. SkEO was added into drinking water at high doses (0.5 to 2.5 g/L) up to day 28 (Trial 1) and then it was reduced to 0.5 < g/L up to day 42 of age (Trial 2). The SkEO-treated water significantly decreased weight gain, feed intake, water intake and feed-to-gain, and...
