HISTO-ANATOMICAL AND PRELIMINARY TLC INVESTIGATIONS ON TRIBULUS TERRESTRIS L. (ZYGOPHYLLACEAE) SPECIES

Using microphotography technique, the cross-sections of root, aboveground stem and leaf were obtained and investigated for Tribulus terrestris L. (Zygophyllaceae) plants in blossom, collected in June 2016, from the surroundings of Craiova City, Dolj County (southwestern Romania). The polyphenols content of the aerial parts (Tribuli herba) was analyzed by thin layer chromatography. One rutin derivative was identified starting from the 12 peculiar chromatographic bands

HISTO-ANATOMICAL AND PRELIMINARY TLC INVESTIGATIONS ON HYPERICUM HIRSUTUM L. (HYPERICACEAE) SPECIES

Starting from Hypericum hirsutum L. plants in blossom, harvested in May 2016, from Rasca Forest, Olt County (Romania), the cross-sections of root, aboveground stem and leaf were acquired and examined through microphotography technique. Also, the content of polyphenols was determined by thin layer chromatography as part of a comprehensive pharmacognostic analysis of aerial parts (Hyperici hirsuti herba). From the 12 separated chromatographic bands, one chlorogenic acid derivative was identified

HISTO-ANATOMICAL AND PRELIMINARY TLC INVESTIGATIONS ON CYNOGLOSSUM OFFICINALE L. (BORAGINACEAE) SPECIES

The cross-sections through root, aboveground stem, leaf and sepal of Cynoglossum officinale L. species, Boraginaceae family, harvested from the geographical area of Valea Cernei, Valcea County (Romania), were obtained and interpreted using microphotography technique. In addition, the polyphenols content of the aerial parts (Cynoglossi herba) was analyzed by thin layer chromatography and established for the reason of pharmacognostic expertise. One caffeic acid derivative was identified from the 15 distinctive chromatographic bands

HISTO-ANATOMICAL AND CHROMATOGRAPHIC RESEARCHES ON ZIZIPHORA CAPITATA L. (LAMIACEAE) SPECIES

Concerning Ziziphora capitata L. (Lamiaceae) species, the paper presents the histo-anatomical analysis of root, aboveground stem and leaf, along with the chromatographic investigations of the polyphenols in the aerial parts. Caffeic acid (126.2 μg/mL) and rutin (171.3 μg/mL) were identified in the 20% methanolic extract of Ziziphorae capitatae herba, by thin-layer chromatography coupled with photodensitometry

HISTO-ANATOMICAL STUDY OF THE ANNUAL OFFSPRING AND LEAF’S LIMB OF VITEX NEGUNDO L. (VERBENACEAE) SPECIES

This paper presents the histo-anatomical study of the annual offspring and leaf’s limb of Vitex negundo species, as an essential stage for the pharmacognostic expertise advancement. The pharmacological importance of the medicinal products (roots, leaves, seeds) obtained from V. negundo was also emphasized

PRELIMINARY CHROMATOGRAPHIC INVESTIGATION OF FOUR STACHYS SPP. (LAMIACEAE) FROM OLTENIA FLORA

Concerning four Stachys spp. (Lamiaceae) from the Oltenia flora, the paper highlights the polyphenolic content of aerial parts through high-performance thin-layer chromatography coupled with photodensitometry. Chlorogenic acid (CA) was identified and quantified in all 20% methanolic extracts of Stachydisherba. The highest CA amount was determined in S. recta (59.88 mg%), followed by S. sylvatica (32.90 mg%), S. officinalis (31.34 mg%), and S. germanica (25.16 mg%), respectively

PRELIMINARY CHROMATOGRAPHICRESEARCH ON SOME SALVIA SPP. (LAMIACEAE)

Salvia genus, representative for the Lamiaceae family as it comprises approximately one thousand different species, is considered for a wide plethora of therapeutic actions, such as antioxidant, anti-inflammatory, hepatoprotective, antitumoral and antidiabetic activity. The paper presents the preliminary chromatographic investigations of the polyphenols in the aerial parts of some Salvia spp. Using high-performance thin-layer chromatography (HPTLC) coupled with photodensitometry, caffeic acid was identified and quantified in the 20% methanolic extracts of Salviaeherba, in descending order, as follows: S. nemorosa (3.096%) > S. verticillata (3.041%) > S. sclarea (2.663%) > S. glutinosa (1.962%) > S. aethiopis (0.926%)

HISTO-ANATOMICAL AND CHROMATOGRAPHIC RESEARCHES ON CAMPANULA PERSICIFOLIA L. (CAMPANULACEAE) SPECIES

The paper presents the histo-anatomical researches on root, rhizome, aboveground stem and leaf of Campanula persicifolia L. (Campanulaceae) species, together with the thin-layer chromatography analysis of the polyphenols content of Campanulae persicifoliae herba. Chlorogenic acid (108.6 μg/mL) was identified in the 20% methanolic extract of the aerial parts
