Bahunia racemosa family, Caesalpiniaceae, is one of the precious resources of the earth. It has played a significant role in human civilization since ancient times. It is tall sized tree growing throughout India, Ceylon, China, and Timor. The different part of this plant contains β-sitosterol and β-amyrin, flavonols (kaempferol and quercetin) and two coumarins (scopoletin and scopolin), tannins etc. Various part of this plant has great pharmacological potential with a great utility and usage as folklore medicine as analgesic, antipyretic, anti-inflammatory, antispasmodic and antimicrobial activity. This review mainly focus on the exclusive review work on the traditional, phytochemical and pharmacological activities of this plant.

Careya arborea Roxb. (Lecythidaceae) is a significant medicinal plant known as kumbhi in Ayurveda. Though, most of the plant parts are used in traditional systems of medicine, bark and leaves constitute the important medicinal parts. The present review gives an account of the updated information on its phytochemical and pharmacological properties. The review reveals that numerous phytochemical constituents have been isolated from the plant possessing hepatoprotective, antioxidant, antimicrobial, anticoagulant, analgesic, antidiarrhoeal and various other important activities. Leaves are used in filaria, colic, loose motions and ulcers. Bark is used as an antipyretic, abortifacient, antipruritic and in smallpox, urinary discharges and rheumatic pain. Since last few decades, extensive exploration has been done to establish the biological activities and pharmacology of the extracts and plentiful chemical constituents including flavonoids, tannins, alkaloids, terpenoids and many other have been isolated.

We have previously reported the isolation of seven hydrolyzable tannins and nine flavonoids from Euphorbia pekinensis Ruprecht. Further investigation about the same plant has led to the isolation of kaempferol, quercetin, kaempferol $3-O-(2'-O-galloyl-{\beta}-_D-glucoside)$, quercetin 3-O-(2'-O-galloylrutinoside), ellagic acid and acetonyl geraniin. These compounds were isolated from this plant for the first time.

Curcuma aeruginosa Roxb. (FamilyZingeberaceae), commonly known as 'pink and blue giner' is widely used in Indian system of medicine since time immemorial. The plant is found well in wild habitat and cultivated in southern India. The plant is distinguished by red corolla lobes and ferruginous or greenish-blue rhizome. Rhizoma is used medicinally as anti-diarrheal, anti-fungal; external use as astringent for wounds. A detailed pharmacognostic evaluation of its rhizome showed total ash 6.1%, acid insoluble ash 1.20%, alcohol soluble extractives 3.70% , water soluble extractives 14.50%, sugar 20.93%, starch 41.85%, and tannins 0.68%. Oh hydro distillation, the rhizomes and sessile tubers yielded 0.17% oil.

Chemical composition was determined to evaluate the quality of Panel ginseng-leaf tea over green teas. Ginseng-leaf tea was shown to contain higher contents of soluble matter, ascorbic acid and lower contents of tannins, as compared to tea leaves. The profiles of ginsenoside and sugar of ginseng-leaf tea were noticeably different from those of ginseng roots and the sample maintained high levels of these components under the manufacturing process. Total unsaturated fatty acids and free amino acids were estimated to be decreased in ginseng-leaf tea as compared to those of ginseng leaves. The compositions of amino acids and minerals in ginseng-leaf tea were similar to those of tea leaves and glutamic acid, aspartic acid, leucine, calcium, potassium, sodium, and copper were found to be major components.

Berberis tinctoria (Berberidaceae), commonly known as Nilgiri Barberry is a common allied species to B. aristata, used in India Traditional Systems of Medicine by the name of '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. tinctoria. Some of the diagnostic features of the root are patches of pericyclic fibre, pitted sclerieds, crystals, 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 also shown some variations. The percentage of berberine as berberine hydrochloride was also calculated through HPTLC densitometric method and it was found almost similar to B. aristata, B. asiatica and B. chitria i.e. 3.36%. Thus it can be explored as a possible source of substitute to B.aristata.

Katsura tree (Cercidiphyllum japonicum Sieb. Et Zucc) leaves were collected, air-dried and extracted with 70% aqueous acetone, then concentrated and sequentially fractionated using n-hexane, methylene chloride ($CH_2Cl_2$), ethylacetate (EtOAc), and $H_2O$. The EtOAc fraction was chromatographed on a Sephadex LH-20 column with various aqueous MeOH eluting solvents and finally treated with acetone-$H_2O$ (7:3, v/v) to isolate a gallotannin. According to the NMR analysis, including HSQC and HMBC, and with the comparison of authentic literature data, the isolate was elucidated as 6-m-digalloyl-1,2,3,4-tetra-O-galloyl ${\beta}$-D-(+)-glucose, one of hydrolyzable tannins and one of gallotannins. The compound was only gallotannin which was firstly isolated from the extracts of Katsura tree leaves, and has not been reported before in domestic tree sources.

Carica papaya is an important medicinal plant used in the management of different disease conditions. Phytochemical screening was carried out using different chemical test, Percentage yield and total phenolic content was evaluated using Folin Ciocalteu method in different solvent system; methanol, ethanol, ethyl acetate, n-butanol and n-hexane respectively. The phytochemical screening of the studies showed the presence of flavonoids, saponins, tannins, terpenoids, glycosides, steroids, carbonhydrate, anthraquinone and alkaloids. The percentage yield of crude extract and total polyphenol content was high in methanol, ethanol and ethyl acetate when compared with n-butanol and n-hexane. The studies show that Carica papaya leave extracts is a potent source of secondary metabolites. The use of the plant in the management of diseases is justified.

Eleven fungal strains previously isolated from the Mexican desert were evaluated for their capacity to use catechin as carbon source in submerged cultures. At 2 g/l of catechin, all strains grew better than the control strains, Aspergillus niger Aa-20. Aspergillus niger PSH and Penicillium commune EH2 degraded 79.33％ and 76.35％ with degradation rates of 0.0065 and 0.0074 g/l/h, respectively, when an initial catechin concentration of 3 g/l was used. Obtained results demonstrated the potential biotechnological capacity of these fungal strains to use condensed tannins as carbon source.

This study was conducted to purify and characterize a polysaccharide fraction from whole parts of Duchesnea indica (Andr.) Focke, which was previously reported to show an antitumor activity by us. The plant was extracted with 5% ethanol for 3 days in the room temperature. The extract was dialyzed by 5% ethanol, and then concentrated by extraction with $excess\;_N-butanol$, followed by gel filtration named Fr. a and b. Each was composed of gallic acid, hexose, pentose, uronic acid and protein, indicating that both fractions were tannic polysaccharide containing protein. Heat treatment of them yielded gallic acid less polysaccharides. They showed a colony stimulating factor activity.
