The naphthaquinones-isohexenylnaphthazarins-are mostly found in the ceratenchymatous cells of the roots of some boraginaceous taxa. A total of 34 naphthazarins and their derivatives have been isolated from these taxa till date.

본 시험은 혼파조합이 하번초형 혼파초지의 건물수량과 사료가치에 미치는 영향을 구명하여 하번초형 혼파초지를 조성하는데 적합한 혼파조합을 찾고자 1998년 9월부터 2001년 12월까지 충남대학교 생명과학대학내 부속 초지시험포장에서 수행하였다. 공시 혼파조합은 tall fescue, kentucky bluegrass 및 perennial ryegrass 중심의 3가지 혼파조합을 공시하였으며 얻어진 시험결과는 다음과 같다 1) 3년 평균 ha당 건물수량, 일반화학적 성분, 건물소화율과 조단백질수량(CPDM) 및 가소화건물수량(DDM)은 혼파조합간에차이가 없었다. 2) 2001년도 6회 마지막 예취시 tall fescue, Kentucky bluegrass 및 perennial ryegrass 중심의 혼파조합에서 tall fescue, Kentucky bluegrass 및 perennial ryegrass의 식생 비율은 각각 42, 35 및 28%이었고, 전체 초종에서 이들 3초종이 차지하는 식생 비율은 모든 혼파조합에서 84%로 나타나 혼파조합이 식생비율에 미치는 영향은 크지 않았다. 기타 초종 중에서는 redtop(8%)과 creeping bentgrass(6${\sim}$7%)의 식생비율이 낮았으며, 특히 red fescue(1${\sim}$2%)는 매우 낮은 식생비율이 보였다. 이상의 결과를 종합해 볼 때, 혼파조합간에 건물수량과 사료가치 및 식생비율에 뚜렷한 차이가 없었던 것으로 보아, tall fescue, Kentucky bluegrass 및 perennial ryegrass 중심의 어느 혼파조합으로 하번초형 혼파초지를 조성하여도 공익목적과 부수적으로 생산되는 목초를 조사료원으로 활용가능성은 크다고 하겠다.

A protocol has been developed for rapid large scale clonal propagation of an aromatic endangered medicinal plant, Hemidesmus indicus R. Br. with the elimination of the problems such as premature leaf fall and callus formation during caulogenesis and rhizogenesis. Multiple shoots were induced from shoot tip and nodal explants on Murashige and Skoog (MS) medium supplemented with 1 mg/L Benzylaminopurine (BAP) and 0.5 mg/L Napthaleneaceticacid (NAA). Addition of 15 mg/L adenine sulphate to the above medium checked leaf abscission completely, reduced the time required for caulogenesis and restored morphogenetic potential after several subcultures. The in vitro grown propagules were rooted in 1/2 MS medium supplemented with 2 mg/L Indolebutyric acid (IBA) +1 mg/L NAA and sucrose 0.7% (w/v). Addition of charcoal at 100 mg/L to the rooting medium quickened root initiation with a complete check on callus formation. The effect of sucrose concentration on both caulogenesis and rhizogenesis was also studied. The resultant plantlets were acclimatized and grown in fields where ninety eight percent of the rooted shoots survived and grew normally. The estimation of the secondary metabolite content in the shoots of the regenerated plant and the mother plant indicated that the concentration of the three secondary metabolites lupeol, vanillin and rutin was similar.

Ratanjot is attributed to eight species of Boraginacae species belonging to genera Alkanna, Arnebia, Maharanga and Onosma and regarded as one of the important herbal drugs of indigenous systems of medicine. The root and root stock, which form the actual drug, are considered to be an anthelmintic, antipyretic and antiseptic. They are also claimed to be useful in burn, eczema, wounds and eruptions, and used for treating the diseases of eyes, bronchitis, abdominal pains, itch, etc. Several workers reported that the Naphthaquinones (arnebins), the main active constituents of the drug, are responsible for its colour and therapeutic efficacy. It is claimed that the Arnebia nobilis was imported to India from Afghanistan but the red coloured roots resembling with A. nobilis were found to be gathered by local people for commercial purposes during the course of botanical surey of Himalayan region. Hence, it is decided to evaluate Arnebia nobilis pharmacognostically. The important macro-microscopic features of this species are roots 1-5 cm broad; outermost xylem with broad vessels and innermost with groups of radially arranged narrow vessels while the middle region occupied by alternate rings of clusters of broad and narrow vessels and presence of pith. Besides the percentage of arnebin-1, -3 and 4 are 9.37, 10.53 and 1.72 respectively.
