    Opis:
    The concentrations of carnosic acid, carnosol and rosmarinic acid in different materials from differentiated (multiple shoot cultures and regenerated plants) and undifferentiated (callus and cell suspension) in vitro cultures of Salvia officinalis were determined by HPLC. The results suggested that diterpenoid (carnosic acid and carnosol) production is closely related to shoot differentiation. The highest diterpenoid yield (11.4 mg g-1 for carnosic acid and 1.1 mg g-1 for carnosol) was achieved in shoots of 10-week-old micropropagated plants. The levels were comparable to those found in shoots of naturally growing plants. Undifferentiated callus and cell suspension cultures produced only very low amounts of carnosol (ca. 0.05 mg g-1 of dry weight). In contrast, content of rosmarinic acid in callus and suspension cultures as well as shoots growing in vitro and in vivo was similar and ranged between 11.2 and 18.6 mg g-1 of dry weight.

    Opis:
    Liquid shoot culture of Salvia officinalis L. in MS medium containing IAA (0.1 mg l-1) and BAP (0.45 mg l-1) was developed and evaluated in relation to shoot multiplication and antioxidant compound (carnosic acid, carnosol and rosmarinic acid) accumulation. In the liquid medium, on average, 3 new shoots per explant (shoot tip) were obtained within 3 weeks. The shoots produced 8.2±0.02 mg of diterpenoids and 31.2±0.29 mg of rosmarinic acid per gram of dry weight. Shoot proliferation and diterpenoid content increased when triacontanol (5, 10 or 20 pg l-1) was added to the liquid medium. In optimum conditions (at 20 pg l-1 TRIA) almost 7 shoots were formed per explant after 3 weeks. An increase in diterpenoid production (expressed as the sum of carnosol and carnosic acid) ranged from 30% to 50% and dependended on triacontanol concentration tested. The level of diterpenoids in triacontanol-treated shoots was similar to the content of compounds in commercial herbal product (dried leaves of S. officinalis) (10-12 mg g-1 dry wt). Triacontanol did not increase rosmarinic acid production, but the content of the phenolic as compound in shoots grown in liquid culture (31 mg g-1 dry wt) was even 24 times higher compared to samples of dried leaves of S. officinalis plants. We also demonstrated that the highest amounts of CA, Car and RA were accumulated in young, top parts of sage shoots. This observation could be useful for improving the selection of material for the extraction of natural antioxidants from S. officinalis.

    Opis:
    Shoot tips excised from shoot culture of Salvia officinalis were encapsulated in 2% or 3% (w/v) sodium alginate and exposed to 50 mM calcium chloride for complexation. Immediately or after 6, 12 or 24 weeks of storage at 4°C, the synthetic seeds were cultured for 6 weeks on half-strength MS medium supplemented with indole-3- acetic acid (IAA) (0.1 mg/l) and solidified with 0.7% agar. The frequency of shoot and root emergence from encapsulated shoot tips was affected by the concentrations of sodium alginate and additives in the gel matrix (sucrose, gibberellic acid, MS nutrient medium) as well as duration of storage. The frequency of shoot and root induction of non-stored synthetic seeds was highest with shoot tips encapsulated with 2% sodium alginate containing 1.5% sucrose and 0.5 mg/l gibberellic acid (GA3). Shoot tips maintained their viability and ability to develop shoots even after 24 weeks of storage when they were encapsulated in 3% alginate with 1/3 MS medium, sucrose (1.5%) and GA3 (0.25 mg/l). Root formation tended to decrease with storage time. Overall, 90% of the plantlets derived from stored and non-stored synthetic seeds survived in the greenhouse and grew to phenotypically normal plants. This procedure can enable the use of synthetic seed technology for germplasm conservation of S. officinalis, a plant species of high medical and commercial value.

    Opis:
    Doświadczenie przeprowadzono w latach 1997–1999 na plantacji dwuletniej. Badano wpływ terminu zbioru na plon świeżego ziela, powietrznie suchego ziela oraz powietrznie suchych liści szałwii lekarskiej (Salvia officinalis L.) odmiany ‘Bona’. Plantacja została założona każdorazowo w roku poprzedzającym badania poprzez sadzenie rozsady szałwii w ostatniej dekadzie maja (w 1996, 1997 i 1998 roku). Rozsadę posadzono w rozstawie 30×40 cm. Surowiec zebrano w dwóch terminach: w maju i we wrześniu. Wykazano istotny wpływ terminu zbioru na plon świeżego ziela szałwii lekarskiej w drugim roku użytkowania plantacji. Plon świeżego ziela uzyskany we wrześniu był większy (190,2 dt·ha⁻¹) aniżeli w maju (104,7 dt·ha⁻¹). Również zawartość olejku eterycznego w surowcu szałwii (liść, ziele) zebranym w drugim terminie (wrzesień) była większa niż w pierwszym (maj).
    The study with sage (Salvia officinalis L.) cv. ‘Bona’ was conducted in the years 1997–1999. The effect of time of harvest on yield of fresh herb sage and yield of air dry herb, yield of air dry leaves sage. The experiment was conducted with sage two-year old. Sage transplants were planted in distance 30×40 cm. The plant material was harvested twice – in May and in September. Harvest date hat significant influence on the weight of fresh sage herb. Yield of fresh sage herb in September was bigger (190.2 dt ha⁻¹) than yield of fresh sage herb in May (104.7 dt ha⁻¹). The percentage quantity of the essential oil in the herb and leaves of sage was depended on the harvest date. The herb and leaves of sage in September had bigger the percentage quantity of the essential oil than in May. The percentage quantity of the essential oil in the leaves of sage, witch was collected in September amounted above 1.5%.

    Opis:
    Introduction: Spice plants are a rich source of biologically active compounds. Processes of drying, limits the development of microorganisms and biochemical reactions in raw herbs, at the same time modifies their chemical composition. Objective: The aim of this work was to evaluate the effect of drying process of selected plants on their antioxidant potential and the content of biologically active compounds. Methods: The herbal materials thyme herb (Thymus vulgaris L.), sage leaves (Salvia officinalis L.) and rosemary leaves (Rosmarinus officinalis) were dried using two methods: convective (at 30° C), and freeze-drying. In both, fresh and subjected to drying processes herbs, changes in total polyphenol and antioxidant potential (with the DPPH radical), vitamin C (in the form of ascorbic acid) and chlorophyll pigments contents, were studied. Results: The highest content of polyphenols and vitamin C was recorded in rosemary, while sage was characterized by the highest content of chlorophylls. It was found that the drying processes caused large losses of vitamin C (ascorbic acid) and dyes in comparison to the fresh material. The highest losses of vitamin C occurred in convection dried sage (95%), while most was preserved in lyophilised thyme (losses 74%). Drying had also influenced the reduction of the content of chlorophylls with the largest loss of these compounds, at 94% observed in the freeze-dried rosemary. However, the content of polyphenols increased, underscoring a large impact on the antioxidant activity of herbs. Conclusions: Drying processes resulted in the release of phenolic compounds, so their content increased three to four times in the case of rosemary and sage. The largest increase was observed in the case of lyophilised thyme. Simultaneously, the antioxidant potential was significantly increased. Herbal droughts proved to be a rich source of antioxidant compounds with promising applications as a food additive.

    Opis:
    The objective of the study was to perform micromorphological analyses of the secretory structures of leaves and stems of oil-bearing industrial plants from the Lamiaceae family such as lemon balm (Melissa officinalis L.), peppermint (Mentha × piperita L.), sage (Salvia officinalis L.), marjoram (Origanum majorana L., syn. Origanum dubium Boiss.), rosemary (Rosmarinus officinalis L.) and common thyme (Thymus vulgaris L.) using light microscope and scanning electron microscope. In addition, an estimation of the content of volatile substances in the plant species under study was performed using GC-MS, as well as the qualitative and quantitative analysis of essential oil, that is an important component in terms of the estimation of raw material applicability for use in the industry. In the epidermal cells of studied plants, 2 types of Lamiaceae-type glandular trichomes were identified: short- and long-stalked capitate glandular trichomes with single- and bicellular secretory capitulum, and peltate glandular trichomes with eight- and over a dozen-cell secretory capitulum. Capitate trichomes were densely distributed on the surface of the epidermis, while peltate trichomes were sparse, though regular, and were situated in depressions. Glandular trichomes were found more frequently on leaves than on stems. The cuticle of the abaxial of leaf was characterized in most cases by the occurrence of larger average diameter peltate trichomes compared to the cuticle of the adaxial side of leaf. Peppermint produced the largest structures accumulating essential oil on the leaves (average diameter of peltate trichomes – 78.48 µm on the adaxial side of leaf, up to 96.43 µm), while on the stem, the highest average diameter of the peltate trichomes was observed in sage (an average of 75.53 µm, up to 85.99 µm). The lemon balm was characterized by the presence of capitate and peltate trichomes with the smallest diameter (an average of 44.26 µm). Lemon balm was characterized by the greatest density of glandular trichomes compared to other plant species. Among the plants studied, the highest content of oil was noted in the case of thyme and peppermint (2.22% and 2.20% v/w, respectively), and the lowest in green parts of lemon balm (0.17% v/w). The isolated essential oils contained predominantly components from the groups of monoterpenes and sesquiterpenes, and it is the presence of those substances that determines the possibility of utilizing the plants studied for a variety of purposes.
