Abstract
Bioactive compounds (BACs) from plants provide unlimited opportunities for pharmaceuticals and natural
agrochemicals development due to vast diversity of secondary compounds. Successful identification and development
of natural products from plants necessitates a standard and integrated approach to screen compounds which aids in
determination of dose response activity. We examined Peperomia pellucida (herb with fibrous root), Cleome viscosa
(herb with tap root), Piper chaba (climber) and Artocarpus lakoocha (tree). In C. viscosa plants, BACs were collected
from ‘Root Exudates Trapping System’ made of Buchner funnel and conical flask, while compounds were collected
from P. pellucida by a self-designed horizontal tube like glass ware with stopper and funnel at either end. BACs are
extracted from stem and leaves dust of P. chaba and A. lakoocha respectively. The basic sequential steps are same
included grinding of plant parts, homogenization, vacuum filtration followed by liquid-liquid extraction in which BACs
were fractionated into two major phases (ethyl acetate layer and aqueous layer). The extracts were further purified into
a single pure compound by repetitive running through column and subsequently followed by thin layer chromatography
and finally subjected to spectral analyses (viz. MS, IR,
1
HNMR and
13
CNMR) for complete molecular characterization. A
new Phenol glycoside was isolated from Peperomia pellucida and Lactam nonanoic acid was recovered from Cleome
viscosa. Four major compounds were recovered from Piper chaba and Artocarpus lakoocha with remarkable bioactivity
but only the important fractions are described here. These new extraction techniques will extend and enhance the
usefulness of plants as renewable resources of valuable chemicals.

Introduction
Bioactive compounds (BACs), otherwise known as the inherent
silent tools of self-protection among plants or semio-chemicals in plants,
have witnessed a dramatic increase in research in recent years. e
use of BACs in different commercial sectors such as pharmaceuticals,
food and agro-industries signify the need of the most appropriate and
standard method to extract these compounds from plant materials
[1]. It is true that development of modern chromatographic and
spectrometric techniques make BACs analysis easier than before but the
success still depends on the extraction methods [2]. e development of
natural products from plants has been given a major research emphasis
to discover biologically active chemicals and biochemical extracts [3].
In recent years, the plant kingdom has become an important source of
major biofertilizers, herbicides, fungicides [4-6] etc. and display great
diversity in chemical structure and activity. ese compounds may
be better than synthetic agrochemicals [7] and are much safer from
health and environmental point-of-view [8] and can also be used as
a renewable novel compound in eco-friendly manner. Considering
this ever-growing demand of plant BACs and the variations that exist
among them, it is necessary to build up a holistic approach for screening
these compounds.
Cleome viscosa L. (Capparidaceae) is widely distributed sticky
herb with yellow flowers, having strong penetrating odor and also
possess several medicinal properties [9-14]. In our field study, we
observed Cleome viscosa is the first and sole appearance species in the
very adverse wasteland. Due to their lot of medicinal properties, wide
distribution as well as first appearance in wasteland, made our interest
to study the BACs from the root exudates of Cleome viscosa.
Peperomia pellucida, L. HBK. belongs to the family Piperaceae. It
is found mainly in South American and Asian countries. It is widely
distributed in the tropical and subtropical regions and is occasionally
cultivated and naturalized as weed [15-17]. is plant possesses a wide
range of medicinal properties [18-21] as well as wide distribution
which possibly indicate the presence of bioactive compounds in the
plants. Our present studies mainly focused on BACs from of Peperomia
pellucida and its allelopathic effects on the surrounding rhizosphere.
Piper chaba, Hunter (Piperaceae) is a relatively less well-known
spice. e stem of the plant is very much effective against cold and
cough and also enhances immunity against this disease. We are
therefore interested to isolate and identify the compound responsible
for its medicinal properties.
Artocarpus lakoocha, Roxb. Moraceae, is a valuable tree native to
India and used for fruit, furniture, timber and feed [22]. Seeds contain
artocarpins (ALA I and ALA II), the isolectins which exhibit high
haemagglutination activity. e tree sheds huge amount of large leaves
towards the end of December till beginning of February forming a very
thick layer of leaf carpet on the ground. We are therefore interested to
study if there are some BACs present in the shedded leaves of Artocarpus
lakoocha.
Our objectives were to establish analytical methodologies, including
the extraction, isolation and characterization of BACs from different
parts of diverse plant types.
