변산향유는 꿀풀과의 국내 자생식물로 식물분류학회지에 처음으로 알려졌다. 초장은 20-35 cm로 작고 잎은 혁질로 윤택이 있다. 꽃은 11월에 보라색으로 개화하는 특징을 갖고 있어 분화 및 지피용 관상소재로 활용도가 매우 높다. 따라서 본 연구는 관상식물로 활용하기 위해 변산향유의 육묘 시 플러그 트레이 종류(128, 162, 200구), 토양조성(원예상토: 마사 1:1, 2:1, 4:1), 파종 립수(1, 2, 3립) 및 추비 농도(0, 250, 500, 1000 mg/L)의 수준을 구명하기 위해 수행하였다. 연구의 결과 변산향유는 트레이의 셀 크기가 커질수록 생육도 비례하여 증가하였다. 토양조성에 따른 생육은 마사토의 비율이 증가할수록 생육이 억제되었다. 셀 당 파종량에 따른 생육은 파종량이 많아질수록 초장, 초폭, 엽장, 엽폭이 감소하였으나 개체당 엽수, 줄기직경, 근장은 큰 차이가 없었다. 추비농도별 처리는 농도가 높아질수록 생육도 증가하는 경향을 보였다. 따라서 변산향유는 육묘시 128구 트레이에 원예상토를 충진한 다음 셀 당 1립 파종하여 재배하며, 추비는 비교적 고농도인 1000 mg/L로 엽면살포하여 육묘하는 것이 가장 효과적일 것으로 판단된다.

The aim of this study is to collate all available data on experiments reporting the antiproliferative, cytotoxic effects of plants and natural products in Morocco in the last two decades. A bibliographic investigation was carried out by analyzing recognized books and peer-reviewed papers, consulting worldwide accepted scientific databases (Scirus, Embase, HighWire, MEDLINE/PubMed, LILACS, Ovid, ScienceDirect, SciELO, Google Scholar). We used medical subject heading terms and the words 'anticancer', 'antiproliferative', 'antineoplastic', 'antitumoral', 'cytotoxic', 'Morocco', to identify relevant articles. Moroccan plants with attributed anti-cancer properties studied as plant extracts that have been evaluated for cytotoxic effects, antitumoral effects, plants with active compounds tested on cancer cell lines, and plants with active compounds that have been assayed on animal models were chosen for this research. In the present study, interest is focused on experimental research conducted on medicinal plants, particularly those which show antiproliferative or cytotoxic activities alongside bioactive components. A total of 20 plant species belonging to 12 families have been identified as active or promising sources of phytochemicals with antiproliferative properties. The plant families, which cover all the species studied in this field, are Lamiaceae (7 species) and Asteraceae (4 species); the most studied species being Argania spinosa (Sapotaceae) and Arisarum vulgare (Araceae), Thymus Genus (Labiateae) and Peganum harmala (Zygophyllaceae). Based on the search results, it is recommended to increase the number of experimental studies and to begin conducting clinical trials with Moroccan plants and their active compounds selected by in vitro and in vivo activities.

Salvia plebeia R. Br. is a plant which has been used as an edible crop and traditional medicine in Asian countries. In this study, HPLC-PDA analysis and countercurrent chromatography (CCC) coupled with reversed-phase (RP) HPLC method were applied to isolate ten isolates from 3.3 g of n-butanol soluble extract from hot-water extract of S. plebeia. The use of CCC enabled us to efficiently fractionate the starting material with less sample loss and facilitate the isolation of compounds from S. plebeia extract using RP-HPLC. The isolates were determined to be caffeic acid (1), 6-hydroxyluteolin 7-O-β-D-glucoside (2), eudebeiolide B (3), (R)-rosmarinic acid (4), homoplantaginin (5), eudebeiolide D (6), plebeiolide C (7), salpleflavone (8), eupafolin (9) and hispidulin (10) based on the spectroscopic evidence.

Rosmarinic acid (1) and methyl rosmarinic acid (2), isolated from the ethyl acetate soluble fraction of the methanolic extract of Salvia miltiorrhiza Bunge (Lamiaceae) were found to be the tyrosinase inhibitors and scavengers of 1, 1-diphenyl-2-picrylhydrzyl (DPPH) radical. Compounds 1 and 2 inhibited the oxidation of L-tyrosine catalyzed by mushroom tyrosinase with $IC_{50}$/ of 16.8 $\mu\textrm{M}$ and 21.5 $\mu\textrm{M}$. respectively. It compared well with kojic acid. a well-known tyrosinase inhibitor. with an $IC_{50}$ of 22.4 $\mu\textrm{M}$. The inhibitory kinetics, analyzed by a Lineweaver-Burk plot, found rosmarinic acid and its methyl ester to be competitive inhibitors with $K_{i}$ of $2.35{\times}10^{-5}M$ and $1.52{\times}10^{-5}M$ respectively. In addition, compounds 1 and 2 showed the scavenging activities on DPPH radical, with $IC_{50}$ of 4.27 $\mu\textrm{M}$ and 3.05 $\mu\textrm{M}$. respectively. These scavenging effects were more potent than that of L-ascorbic acid ($IC_{50}$ = 11.75$\mu\textrm{M}$).

Peppermint (Mentha piperita L.) belongs to a member of the mint family (Lamiaceae) and is widely used in food, cosmetics and medicines. This study was carried to investigate the variation of essential oil content and its composition during callus subculture of M. piperita. For callus induction from the leaf explant of peppermint, the basal medium was supplemented with various concentrations of 2, 4-D. The best callus induction rate (93%) of M. piperita. was obtained in MS medium containing 2 mg/l 2, 4-D. The induced peppermint callus maintained on Lin-Staba medium were studied during a period of 20th subcultures for the stability of essential oil production. Growth rates of peppermint callus increased during prolonged subculture. However, there was a progressive decrease of essential oil content and unstability of monoterpene productions when callus cultures were serially subcultured.

Coleus forskohlii Briq, of the family Lamiaceae yields a valuable secondary metabolity known as forskolin which is a labdane diterpenoid.. Coleus forskohlii is the only known source of this compound. Forskolin is used in medicine for the treatment of glaucoma, congestive cardiomyopathy and asthma. Morphogenic callus was induced from young leaves on MS medium augmented with NAA and BA. These calli, when subcultured on MS with KN alone gave rise to shoots. The regenerated shoot developed good root system on MS medium fortified with NAA. The fully grown plantlets were transferred to soil for acclimatization. Coleus plant is mainly infected by a fungi Lasiodiplodia theobromae which causes root rot disease. The fungal culture filterate (ECE) of Lasiodiplodia theobromae, has been used in regeneration media to find the MIC and further to select resistant plants to the pathogen. In the present study 40% ECF in the medium showed maximum inhibition and is there fore considered as the MIC level of Coleus forshohlii. This data could prove to be useful for the future for selecting a resistant C.forskohlii plant against the root disease caused by L. theobromae.

Gemcitabine is an anti-cancer drug with clinically uses in the treatment of various neoplasms, including breast, ovarian, non-small cell lung, pancreaticand cervical cancers, T-cell malignancies, germ cell tumours, and hepatocellular carcinomas. However, it has also been reported to have many adverse effects. Naturally occurring anti-mutagenic effects, especially those of plant origin, have recently become a subject of intensive research. The present study was therefore designed to investigate the anti-mutagenic effects of Salvia merjamie (Family: Lamiaceae) plant extracts against the mutagenic effects of gemcitabine. The anti-mutagenic properties of Salvia merjamie were tested in Inbred SWR/J male and female mice bone marrow cells. The mice were treated in four groups; a control group treated with 30 mg/kg body weight gemcitabine and three treatment groups, each with 30 mg/kg body weight gemcitabine together with, respectively, 50, 100 and 150 mg/kg body weight Salvia merjamie extract. Chromosomal aberration and mitotic index assays were performed with the results demonstrating that Salvia merjamie extract protects bone marrow cells in mice against gemcitabine induced mutagenicity. This information can be used for the development of a potential therapeutic anti-mutagenic agents.

Leucas aspera Link. (Lamiaceae) is an important medicinal plant in indigenous systems of medicine in India and commonly known as 'Thumbai'. It has various ethnomedicinal values as various traditional communities find diverse medicinal properties. It is used as antipyretic, stimulant, expectorant and diaphoretic drug. The present communication deals with the detailed pharmacognostical evaluation of whole plant of L. aspera collected from five different geographical zones of the country-Uttar Pradesh, Orissa, Karnataka, West Bengal and Gujarat. The botanical characters and TLC fingerprint profile of all the samples were quite similar but some variations were observed in physicochemical parameters. However, some microscopical characters and TLC profile can be used as diagnostic characters for identification of L. aspera, for example amphistomachic leaves and two types of trichomes-abundant, non glandular, uniseriate, 1-3 celled and few glandular, 2-5 celled stalk with rounded tip. Presence of some components at $R_fs-0.56$, 0.65 and 0.76 under UV 366 and at $R_fs-0.31$, 0.43, 0.60, 0.76 and 0.82 under visible light after derivetization in TLC profile may also be used as diagnostic character.
