Korean folk medicine 'Ggeong Yi Da Ri' has been used mainly as remedies for stomach trouble, bruise and neuralgia. The botanical origin of the crude drug has not been studied pharmacognostically. To clarify the botanical origin of 'Ggeong Yi Da Ri', the morphology and anatomy of leaf and stem were examined for the Korean species of Thalictrum plants, such as T. acetaefolium, T. aquilegifolium, T. filamentosum, T. minus var. hypoleucum, T. minus var. stipellatum and T. rochebrunianum. The botanical origin of 'Ggeong Yi Da Ri' was clarified as the leaf and stem from Thalictrum aquilegifolium and T. filamentosum.

Berberis chitria (family Berberidaceae) has a close affinity with B. aristata, used in traditional systems of medicine as a drug 'Daruharidra' for skin disease, jaundice, affection of eyes, and rheumatism. Keeping this in view, in the present study attempts have been made to identify marker characters of B. chitria in order to differentiate the two species. Some of the diagnostic features of the root are patches of pericyclic fibre, pitted sclerieds and berberine containing cells and heterocyclic medullary rays. Besides, the physicochemical characters such as total ash; acid insoluble ash; alcohol and water soluble extractive; tannins; sugar and starch percentages has shown variations. The percentage of berberine as berberine hydrochloride was also calculated through HPTLC densitometric method and it was found little higher than B. aristata and B. asiatica i.e. 3.16%. Thus, this species can be utilized as a possible substitute to Daruharidra.

'Pae Jang (敗醬)' is one of Chinese crude drugs used mainly as a edema, abdominal pain and hemoptysis, etc. With regard to the botanical origin of 'Pae Jang', it has been considered to be Patrinia scabiosaefolia of Valerianaceae, but there has never been studied pharmacognostically. To clarify the botanical origin of the 'Pae Jang', we studied on the anatomical characteristics of the roots of three species growing in Korea. Through our studies, the botanical origin of 'Pae Jang' from Korea was proved to be the under ground portions of Patrinia scabiosaefolia and Patrinia villosa.

The seeds of Abrus precatorius L. (Family- Fabaceae) constitute the drugs Abrus, Gunja, or Ratti in commerce. In the Indian System of Medicine, the seeds are used for sciatica, paralysis, headache, dysentery, diarrhoea, leprosy, ulcer, nervous disorders, alopecia, as well as anti-inflammatory, antidiabetic, antibacterial, antitumor, sexual stimulant and abortifacient. Seeds are poisonous and therefore are used after mitigation. The protein abrin is responsible for the highly toxic properties of seeds. Quantitative HPTLC analysis of the methanolic extract of seeds determined the presence of 0.4018% gallic acid and 0.4009% glycyrrhizin. The present study was undertaken to develop an HPTLC method, as well as ascertain the physico-chemical, morphological and histological parameters to establish the authenticity of A. precatorius seeds.

The Chinese crude drug, 'Yong Dam (龍膽)' which is derived from the root of Gentiana plants of the family Gentianaceae, has been used as remedy for stomachic, intestinal catarrh, convulsion, etc. With regard to the botanical origin of 'Yong Dam', it has been considered to be Gentiana species of Gentianaceae, especially Gentiana scabra, but there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'Yong Dam' from Korea, we studied on the anatomical characteristics of Gentiana species growing wild in Korea i.e. Gentiana scabra var. buergeri, G. uchiyamai, G. triflora, G. axillariflora var. coreana and of 'Yong Dam' from Korea on Korean market. Through our studies, the botanical origin of 'Yong Dam' from Korea was proved to be Gentiana scabra var. buergeri and Gentiana axillariflora var. coreana.

Ig Mo Cho (益母草) has been used as remedy for invigorating blood circulation to remove blood stasis and relieving edema by inducing diuresis. With regard to the botanical origin of Ig Mo Cho, it has been considered to be Leonurus spiecies of Labiatae, but there has never been pharmacognostical confirmation on it. To clarify the botanical origin of Ig Mo Cho from Korea, the anatomical characteristics of Leonurus japonicus and L. sibiricus were studied. As a result, the botanical origin of Ig Mo Cho from Korea was proved the herba of Leonurus japonicus.

‘Maig Moon Dong(麥問冬)’ is one of the chinese crude drugs used mainly to cure a cough and sputum, etc. With regard to the botanical origin of ‘Maig Moon Dong’, it has been considered to be Liriope species of Liliaceae, but there has not been studied pharmacognostically. To clarify the botanical origin of Maig Moon Dong, we studied on the anatomical characteristics of Liriope and Ophiopogon species growing wild in Korea i.e. L. platyphylla, L. spicata, O. jaburan, O. japonicus and Maig Moon Dong from Korea. As a result, the botanical origin of Maig Moon Dong from Korea was proved as Liriope platyphylla and L. spicata.

The problems caused by synthetic pesticides have led the need for effective biodegradable pesticides with greater selectivity. Botanical pesticides are generally recognized as safe in agriculture systems. Thus, they have been regarded as attractive alternatives to synthetic chemical pesticides for the pest management. Both lower efficacy and higher costs of production make botanicals more expensive to use than conventional pesticides. Moreover, only a small portion of plant-derived metabolites among a number of bioactive metabolites are in use because commercialization of botanicals is inhibited by several problems such as toxicity, or high production cost. However, with the growing acceptance of botanical pesticides as an efficient crop protection alternative resulting in increasing demand, plant-based pesticides will play a significant role in achieving sustainable agriculture in future.

A simple quantitative HPLC method has been developed for differentiating two plants of Asteraceae family viz. S. costus and A. lappa by using a pharmacologically active constituent chlorogenic acid and symmetry C18 column clubbed with a binary gradient using acetonitrile: 0.1% phosphoric acid and detected using a PDA at 327 nm. Quantitatively chlorogenic acid was found to be more in A. lappa (0.140%) than in S. costus (0.087%).

Korean folk medicine 'Koaeng I Bab' has been used to cure hemorrhoid, boil and dermatopathy and as an antidote. The botanical origin of the crude drug has not been studied pharmacognostically. To clarify the botanical origin of 'Koaeng I Bab', the morphological and anatomical characteristics of the leaves of Oxalis species growing in Korea, i.e. O. acetosella, O. acetosella var. purpurascens, O. corniculata, O. obtriangulata were studied. As the result, the botanical origin of 'Koaeng I Bab' has been proved to be O. corniculata and O. acetosella var. purpurascens.
